Autotrophs, such as plants, use light to make their own food. What happens to the light absorbed by a plant during photosynthesis?

Answers

Answer:

When light energy reaches the pigment molecules, it energizes the electrons within them, and these electrons are shunted to an electron transport chain in the thylakoid membrane.

Explanation:

During photosynthesis, light absorbed by plant is used for energizing electrons  for an electron transport chain to take place in thylakoid membrane.

What is photosynthesis?

Photosynthesis is defined as the  process by which plants and other photosynthetic organisms convert the light energy in to chemical energy  through the process of cellular respiration.

Some of the energy which is converted  is stored in the form of  molecules of carbohydrates like sugar and starches  which are made up of from carbon dioxide and water . Photosynthetic organisms which can perform photosynthesis  are algae and cyanobacteria. Photosynthesis is largely responsible for producing and maintaining the percent  of oxygen in earth's atmosphere.

The process begins with proteins absorbing light energy  which are called reaction centers and have a green pigment which is called chlorophyll . In plants ,these pigments are present inside organelles which are called chloroplasts while in bacteria they are present in plasma membrane.

If I put a potato in ammonia (a base) then the activity of catalase will decrease  because the pH level will be to basic for any catalytic (catalase) activity.

What is catalase?

An enzyme called catalase causes (catalyzes) the process by which hydrogen peroxide is broken down into water and oxygen.

Catalase, which is widely distributed in organisms that live in the presence of oxygen, inhibits the buildup of peroxide, which is continuously created by multiple metabolic reactions, and shields cellular organelles and tissues from harm. Catalase is primarily found in the liver of mammals.

Therefore, If I put a potato in ammonia (a base) then the activity of catalase will decrease  because the pH level will be to basic for any catalytic (catalase) activity.

Describe the famous experiment related to gravity that Galileo may have performed. Include the results. Also, state whether the results support the law of gravity. Explain your answer.

Answers

Answer:

Galileo performed a famous experiment where he used a ball rolling on a ramp (inclined plane) to study the motion of objects under the influence of gravity. The ramp allowed him to make more precise measurements because the ball moved more slowly along the ramp than if it were simply dropped. Galileo discovered through this experiment that the objects fell with the same acceleration, proving his prediction true, while at the same time disproving Aristotle's theory of gravity (which states that objects fall at speed proportional to their mass). Galileo's conclusion from this thought experiment was that no force is needed to keep an object moving with constant velocity. Newton took this as his first law of motion. One result of the experiment surprised Galileo, and one surprises us. Galileo found that the heavy ball hit the ground first, but only by a little bit. Except for a small difference caused by air resistance, both balls reached nearly the same speed. And that surprised him. According to history, Galileo’s experiment on falling bodies largely contributed to Isaac Newton’s Law of Gravity. In Galileo’s experiment, he is said to have dropped balls from the Leaning Tower of Pisa. The balls were made of the same material but had different masses. Galileo set out to prove that the time it took for these objects to reach the ground would be the same. Galileo proved that objects reached the ground at the same time.

How does the introduction of invasive species such as the brown tree snake upset the stability of the legal system

Answers

Answer:

Invasive species compete for the same natural resources such as food and water which the native species also need for survival.

Explanation:

Invasive species upset the stability of the ecosystem because the prey in their new environment does not have the needed defense against them. They also upset the food chain, consume so much, and overpopulate in the new territory thus causing the extinction of the native species.

The introduction of brown tree snakes in Guam disrupted the ecological system as their population increased rapidly because their preys in this new environment lacked the ability to defend themselves against the brown tree snakes. For this reason, more than twelve native birds in the Guam Islands went into extinction. They also consumed the natural resources needed for the survival of the native species.

Aerobic respiration has 3 stages: glycolysis, Kreb's cycle, electron transport
chain. What happens in each stage? How many ATP molecules made during
each stage?

Answers

What happens in each stage?

GLYCOLYSIS: "In glycolysis, glucose—a six-carbon sugar—undergoes a series of chemical transformations. In the end, it gets converted into two molecules of pyruvate, a three-carbon organic molecule. In these reactions, ATP is made, and NAD+ is converted to NADH." (Khan Academy)

KREB'S CYCLE: "This is a central driver of cellular respiration. It takes acetyl CoA—produced by the oxidation of pyruvate and originally derived from glucose—as its starting material and, in a series of redox reactions, harvests much of its bond energy in the form of NADH, FADH2, and ATP molecules. The reduced electron carriers—NADH and FADH2—generated in the TCA cycle will pass their electrons into the electron transport chain and, through oxidative phosphorylation, will generate most of the ATP produced in cellular respiration." (Khan Academy)

ELECTRON TRANSPORT: "In the electron transport chain, electrons are passed from one molecule to another, and energy released in these electron transfers is used to form an electrochemical gradient." (Khan Academy)

How many ATP molecules made during each stage?

GLYCOLYSIS: 2 ATP

KREB'S CYCLE: 2 ATP

ELECTRON TRANSPORT: 34 ATP

Khan academy is the best for breaking down processes in chemistry! I used khan all the time when I had trouble understanding chemistry last year.

Stage 1: Splitting Glucose stage
The word glycolysis initially means “glucose splitting,” which is exactly what happens in this stage. Enzymes split a molecule of glucose into two molecules of pyruvate (also known as pyruvic acid).

Stage 2 The Krebs Cycle

Recall that glycolysis produces two molecules of pyruvate (pyruvic acid). These molecules enter the matrix of a mitochondrion, where they start the Krebs cycle. This cycle is at the center of cellular metabolism, playing a starring role in both the process of energy production and biosynthesis. It finishes the sugar-breaking job started in glycolysis and fuels the production of ATP in the process. It is also a central hub in biosynthetic reactions, providing intermediates that are used to build amino acids and other molecules. The citric acid cycle enzymes are found in all cells that use oxygen, and even in some cells that don't. The examples included here are taken from several different organisms.

Electron Transport Chain Stage.

The electron transport chain is a cluster of proteins that transfer electrons through a membrane within mitochondria to form a gradient of protons that drives the creation of adenosine triphosphate (ATP). ATP is used by the cell as the energy for metabolic processes for cellular functions.

с
The movement of glucose through the membrane requires ATP hydrolysis
D
Na transport out of the cell requires ATP hydrolysis

Answers

Answer:

The correct answer is - D . Na transport out of the cell requires ATP hydrolysis

Explanation:

Sodium-ion moves or transported from the inside of the cell to the outside the cell by the process called active transport. Active transport takes place takes place when the movement is against the concentration gradient to a higher concentration area through the cell membrane.

Active transport requires energy in order to transport the molecules or ions from low concentration to high concentration. In sodium-potassium pump get the energy from the hydrolysis of the ATP.

The given diagram represents the transport of sodium out of the cell using active transport. Active transport utilises the energy or ATP released during respiration. The correct answer is that sodium is transported out of the cell requires ATP.

Active transport is defined as the transport in which molecules move from lower to higher concentration, against the concentration gradient. The active transport requires the hydrolysis of energy to move across the cell. The sodium-potassium pump follows the active transport, such that:

The pumping of ions against the concentration gradient requires the addition of energy. The high-energy molecule is used to facilitate the active transport of sodium ions during the sodium-potassium pump.

Therefore, the image represents the sodium is transported out of the cell by active transport.

Suppose you do this test on a hypothetical Staphylococcus species with the antibiotics penicillin (P-10) and levoflaxacin (L-5). You record identical zone diameters of 25 mm for the levoflaxacin and penicillin disks. Which antibiotic would be more effective against this organism? What does this tell you about comparing zone diameters to each other and the importance of the zone diameter interpretive chart?

Answers

Answer:

Levoflaxacin

Explanation:

Levoflaxacin is the antibiotic which is more effective than penicillin against Staphylococcus species because Staphylococcus species are more resistance to penicillin  while not resistance against levoflaxacin antibiotic, so the Levoflaxacin is more effective against Staphylococcus species of bacteria.  Levoflaxacin kills about 99.9% of Staphylococcus species so we can say that it is more effective than penicillin.

The most effective antibiotic would be Levoflaxacin and this would be seen by comparing the diameter zones, which shows why the interpretation of these zones is so beneficial.

We can arrive at this answer because:

Staphylococcus is a genus of bacteria that has been resistant to penicillin since the time penicillin was discovered.In this case, when applying penicillin to a Staphylococcus culture, the bacterium can reproduce and form large zones in diameter.Staphylococcus is not resistant to Levoflaxacin and therefore it will form discs with small diameters because it will not be able to reproduce efficiently.

In this case, we can state that the analysis and interpretation of the diameter zones are very important to determine the resistance of bacteria to different types of antibiotics.
