3. ADP + Pi → ATP is best classified as which type of reaction?

Answers

Answer 1

Answer:

Hi Motomasa, you are correct that there is a bit of a misrepresentation, or at least a glossing-over, in the standard description of the function of ATP. The "energy-storing" capacity of ATP is NOT in the forming and breaking of the covalent phosphate to phosphate bonds. ATP -> ADP releases energy by two mechanisms. First because the process of hydrolysing the y-phosphate (the terminal phosphate) releases energy. And second because ATP and ADP are maintained out of equilibrium in cells. The action of utilizing an ATP brings the system closer to equilibrium, which releases energy.

There is a required energy input to break the phosphate to phosphate bond. This is the activation energy. However, the energy released upon hydrolysis and moving the system towards equilibrium are of greater magnitude than the activation energy input. I hope this helps!

Publishing can play a major factor in how a scientist is regarded. This is because the number of publications scientists produce can affect who gets a raise, who gets hired, who gets fired, and who gets funding to do more experiments. Consequently, a phenomenon is known as “salami-slicing” has arisen in science. Instead of publishing a large comprehensive study containing all the results as one large paper, scientists often slice up the work into the smallest units possible and publish these as several separate papers—often in different journals.

Research the phenomenon of scientific salami slicing, and list at least two possible ethical problems that can arise from this practice.
Explain how this practice can affect the way that scientific information is disseminated to nonscientists.
Create a suggestion for a policy that scientists or science journals could follow that would reduce the amount of salami-slicing that occurs in research. Suggest any problems that the policy might cause.

Answers

Salami slicing is the procedure of dividing one single article research into several publications. It is an unethical practice because hampers the healthy competence between scientists for research (job) positions.

In the phenomenon referred to as 'salami slicing', a group of similar research articles published by the same research group are considered 'slices' of the same salami.

This practice can affect not only the work of scientists but also journalists who might report the same results once and again.

A possible solution for this problem is to create a Review Board consisting of experts capable of identifying salami slice articles and then punish the responsible parties.

CAN SOMEONE WHO DID THE CELERY STALK OSMOSIS LAB ANSWER THESE QUESTIONS? 50 POINTS
1. What is osmosis?

2. Celery is composed of millions of plant cells. Do these cells contain any water?
Yes
3. Did the cut celery in step 8 & 9 show any color change that would indicate that the water did enter the celery cells?

4. If you placed the celery into a bottle of colored water that was 35% sugar, would the colored water be seen in the celery? Why or why not? (HINT: Drawing a diagram of this scenario may help – 35% sugar is a very concentrated solution…)

Answers

Answer:

1. Osmosis is the spontaneous net movement or diffusion of solvent molecules through a selectively permeable membrane from a region of high water potential to a region of low water potential, in the direction that tends to equalize the solute concentrations on the two sides. 

2. Plants obtain water through their roots. Water present in the soil (or air, in the case of air plants) enters the plant through the epidermis of the root. The epidermis is a very thin single layer of cells. The water passes through the membranes of plant cells and also fills the spaces in between the cells.

3. This experiment allows you and your child to talk about the circulatory system and "capillary" action. The small "vessels" in the celery stalks carry the water and color to the leaves, like the way blood travels through your body.

4. A great way to introduce basic science concepts are through fun and visual experiments such as this Celery Experiment. It requires just a few items and is a fun way to teach children about how a plant absorbs water. This process is called Osmosis. We will learn about how plants absorb water using colored water and celery stalks.

A plant dies if it’s pholem tissue removed why

Answers

Question:-

A plant dies if it’s pholem tissue is removed. Why?

Answer:-

When the phloem is removed, no substance is transported, the plant does not have the necessary requirements to carry out the process (photosynthesis), and finally the plant dies.

Phloem is composed of various special cells called companion cells, phloem fibers, and phloem parenchyma cells.
Phloem helps the plant by carrying sugar,amino acids and other nutrients from roots to the leaves,stem and other parts of the plant. If the phloem is removed then the transportation of substances won't take place and plants would not get the needed requirements to carry out its process and at last the plant dies.

Cell membrane is like the doors on a car. They regulate what goes in/out. The cell wall in a plant cell is like the frame on a car. The frame supports the car as the cell wall supports the plant.

The Nucleus is like the front seat of your car because the driver is in control of what the car does, goes, and what happens inside of the car.

Vacuoles is like the Trunk of your car because you store food, water and other wastes into your trunk, like were all the things go in the vacuoles.

The compression stroke in a car engine is like chloroplasts because it gas to fuel a car the same way chloroplasts convert solar energy in to chemical energy for a cell.

Mitochondrion is like the battery on a car. It gives the motor energy so it can run like the mitochondrion produces energy for the cell.

Eyespot is like a radio, because in some cars, radios pull power directly from the battery from the car battery, and this is why you will get the car radios on while the engine is off

Explanation:

The internal structures found in a typical photosynthetic Euglena are as follows:

Pellicle: A thin, flexible membrane that supports the plasma membrane and helps them to change shape

Plasma Membrane: The selectively permeable membrane that protects the inner content of the cell from the outside environment

Cytoplasm: A jelly-like substance distributed throughout the cell that contains all the cell organelles

Chloroplast: Contains the green pigment chlorophyll that helps them to produce food using sunlight by photosynthesis

Nucleus: A membrane-bound organelle that contains the genetic material, DNA. It also contains a distinct nucleolus that contains RNA and helps the cell to synthesize proteins

Mitochondria: The energy-producing organelle that forms ATP. All cellular activities such as movement and reproduction are performed using the mitochondrial energy source

Ribosomes: Consists of RNA and proteins, and are responsible for producing all cellular proteins

Golgi Apparatus: Manufactures, stores, and transports large molecules such as carbohydrates and proteins within the cell

Endoplasmic Reticulum: The extensive network of membranes that helps to package and transport proteins to different organelles. It is of two types: rough endoplasmic reticulum (RER) – containing ribosomes attached to it; and smooth endoplasmic reticulum (SER) – devoid of ribosomes

Lysosomes: Small membrane-bound organelles filled with hydrolytic enzymes that break down large molecules such as carbohydrates, fats, and proteins

Contractile Vacuole: It maintains the water and salt balance within the cell

Reservoir: The inward pocket present near the base of the flagella where contractile vacuole dispels excess water

Flagellum: A long whip-like structure attached externally to the cell body that helps in cell movement. An amoeba contains two flagella, a short one that does not protrude out of the cell, and a long one that helps in swimming

Eyespot: A region that is highly colored and contains red-colored carotenoid pigments that help in the detection of light. It is sometimes called a stigma

Photoreceptor: Also known as the paraflagellar body, it is the light-sensitive region located near the flagellum that helps to detect light. It also helps in their movement towards and away from light stimuli, a process known as phototaxis  

Paramylon: They are stored starch-like carbohydrate granules composed of glucose produced during photosynthesis. Paramylon enables the organism to survive in low-light conditions when photosynthesis is not possible by acting as the food reserve for the cell. When the paramylon is enclosed in a sheath of polysaccharide, it is called the paramylon sheath of pyrenoid.

The flagellum of euglena, can be compared to the wheels of a car, as they are responsible for the movement of both.

What is Euglena?

Euglena is a genus of single-celled flagellated algae that can occur either as free cells or in colony form.

What is flagellum?

Euglenophytes have the presence of flagella as their main characteristic. They have two flagella, one longer than the other. The smaller flagellum does not emerge from the cell. The larger one is mainly used for locomotion.

With this information we can conclude that euglena has flagella for locomotion just as cars have wheels for locomotion.
