Cyclic AMP phosphodiesterase is an enzyme that catalyzes the conversion of cyclic AMP to a different molecule. Which of the following best predicts the effect of inhibiting cyclic AMP phosphodiesterase in a muscle cell stimulated by epinephrine?
The concentration of cyclic AMP will decrease because adenylyl cyclase will no longer be activated.
The G protein will diffuse out of the cell because it will no longer bind to the plasma membrane.
Phosphorylase kinase will remain active because protein kinase A will no longer be deactivated.
Glycolysis will stop because epinephrine signaling will no longer stimulate glycogen breakdown.
Answer:
Phosphorylase kinase will remain active because protein kinase A will no longer be deactivated.
Explanation:
Phosphodiesterase is an enzyme that has the function of hydrolyzing cAMP by converting it to AMP. As a result, a protein called kinase is inactivated and lipids break down in fat metabolizing cells. CAMP is a cellular messenger. Cyclic AMP phosphodiesterase, in turn, is an enzyme that catalyzes the conversion of cyclic AMP into a different molecule. as a result, a molecule called kinase A is deactivated. However, if inhibition of cyclic phosphodiesterase AMP in a muscle cell stimulated by adrenaline, Kinase A will not be deactivated, so phosphorylase kinase will remain active.

Explanation:
Special lymphatic vessels, called lacteals, absorb dietary __________ that are not absorbed by the blood capillaries.
Answer:
This question lacks options, options are:
A. water
B. glucose
C. vitamins
D. amino acids
E. lipids
The correct answer is E.
Explanation:
Lipids are a heterogeneous group of organic compounds divided into fats or oils, phospholipids and cholesterol esters. The lymphatic vessels are responsible for the transport of lipids and fat-soluble vitamins (A, D, E and K), which are absorbed through the digestive tract, that is, they act as capturers of fats and excess fluids from the human body, always present in the blood vessels. They do not carry blood, but lymph, a clear liquid. They play an important role in the transport of fats, in the recovery of fluids that escape from the blood capillaries and in the fight against infections. In the small intestine, specialized lymphatic capillaries transport lipids from the diet to the lymphatic vessels and, ultimately, to the blood. The presence of these lipids makes the lymph drained through the small intestine appear creamy white.
Photorespiration lowers the efficiency of photosynthesis by removing which of the following from the Calvin cycle?
a. ATP molecules
b. carbon dioxide molecules
c. ribulose bisphosphate molecules
d. RuBP carboxylase molecules
e. glyceraldehyde phosphate molecules
Answer:
Option B.
Carbondioxide molecules.
Explanation:
Photorespiration lowers the efficiency of photosynthesis by removing carbondioxide molecules because photorespiration begins in Calvin circle as a result of Rubisco acting on oxygen instead carbondioxide and it's function is to first initiate and input carbondioxide in Calvin circle. Therefore instead of using Carbondioxide as the pathway , it uses oxygen. Carbondioxide is use for photosynthesis because it combine with water in the presence of light energy and chlorophyll to produce glucose and oxygen.

Which of the following factors are determining factors in a biome?
sunlight
wind speed
air pollution
temperature
rainfall
You can chose multiple.
Answer:
-temperature and rainfall
Explanation:
Terrestrial biomes are defined as regions of similar vegetation and climates. Certain types of vegetation have specific growth requirements for their optimal water and temperature. They tend to thrive within regions where these needs are met, thus making up the dominant plant types.
At or close to the equator, biomes are warmer due to the high intensity of sunlight (the equatorial regions the most sunlight), and warmer air holds more moisture, making the regions more prone to rainfall.

Choose 1 Transport Mechanism in a cell and make a relatable analogy based on your experience recently. Explain .
Answer:
Active transport across membranes is like refilling an empty soda can after pouring the soda into a cup. It takes effort (energy in the form of ATP) to pour the soda back into the can, it wouldn't typically happen on its own.
Explanation:
Cells use several transport mechanisms to move substances across their plasma membranes. Plasma membranes control all movement of substances through passive transport, which does not use energy; and active transport which requires chemical energy in the form of ATP.
Active transport moves substances out of cells against their gradients. In the cell, glucose can be transported inwards for respiration. However, because the internal environment is typically concentrated, (and glucose is needed in high amounts) this requires the use of transport enzymes and ATP.
The question above is intended to assess your ability to relate cell transport types to your personal experience. For that reason, I can't answer this question for you, but I'll help you answer it.
As you may already know, cell membranes limit the transport of substances into and out of the cell. This makes the cell create a mechanism that allows it to absorb and expel substances. These mechanisms are the cell transport mechanism.
Below you will find a definition of cell transport:
Simple diffusion: Allows molecules to be transported into or out of the cell. In this process, they leave the place where they are in greater concentration to a place with less concentration. An example of this can be seen in an elevator that is full of people, reaching the point where some people need to get out of the elevator and stay outside, where there is no one.Osmosis: Allows the transport of water into or out of the cell. In this case, the water leaves where it has a lower concentration of salts and goes to where it has a higher concentration of salts. An example of this can be seen when you need to add milk to dilute your powdered chocolate.Facilitated diffusion: This also allows the transport of substances into or out of the cell. These substances leave the place where they are in greater concentration to the place of lesser concentration, but leave with the help of specific proteins. An example of this can be seen when the postman takes your package from the post office and takes it to your house.Active transport: Occurs in the same way as facilitated diffusion, but it is the only type of cell transport that allows the cell to spend energy. An example of this occurs when you have to leave the house and go to the post office to pick up your package.More information:

Encyclopaedia Britannica's editors oversee subject areas in which they have ... from intrusive rocks on the basis of their texture and mineral composition
Explanation:
The presence of a layer of extrusive rocks is due to a single volcanic eruption and its presence in the middle of a rock formation may be because these rocks are younger than the surrounding rock formations.
What are extrusive rocks?The presence of a layer of extrusive rocks in the middle of a rock formation refers to the geological history of the area. These rocks are formed from lava that has been erupted from a volcano and cooled quickly on the Earth's surface followed by the cooling at the surface of the Earth. This suggests that a volcanic event has occurred in the area.
When a volcanic eruption occurs, lava is ejected from the volcano and flows onto the Earth's surface followed by its solidification into extrusive rocks which have fine-grained texture.
The presence of extrusive rocks in the middle of a rock formation may be due to a single volcanic eruption or these rocks are often younger than the surrounding rock formations.
Therefore, the presence of extrusive rocks is due to a single volcanic eruption and may be younger than the surrounding rock formations.

If drawn into a food web, why would every arrow point to the decomposers?
Decomposers are organism that decomposes the dead and decay matter. So all arrows in a food web are pointed toward decomposers because at last, after decaying, eaten by decomposers.
What are decomposers?Decomposers are living organisms that feed on the dead and decayed matter of plants and animals. The main decomposers are bacteria, fungi, etc. They live on decaying matter.
They are called the cleaners of the environment because they decompose the matter and convert it into manure and fertilize the soil. Thus, they learn about the environment. At last, when every living matter dies, they are eaten by decomposers.
Thus, Decomposers are those that break down decaying and dead materials. Decomposers are therefore the target of all arrows because they are, in the end, the ones who consume the decayed matter.

Glyceraldehyde 3-phosphate (G3P) is created.
G3P is used to make sugar.
Explanation:
edge 2020
i'm just different
During the reduction stage of the Calvin cycle, the 3-PGA molecules produced by carbon fixation are transformed into simple sugar molecules – glucose.
In this step, the energy is supplied by the ATP and the NADPH produced during the light-dependent photosynthesis reactions.
ATP, or NADPH, is used to transform the 3-PGA molecules into three-carbon sugar molecules (G3P molecules). The name “G3P” comes from the fact that NADPH gives electrons to, or breaks down, a 3-carbon intermediate to form G3P.
Carbon dioxide in the atmosphere undergoes a redox reaction to glucose. This redox reaction requires the total reduction of CO2 using the electrons available in the oxidation of the NADPH. Thus, the dark reactions are a redox pathway. Calvin-Benson cycle.

In the tonicity of red blood cells lab, if you had chosen the strategy "I will measure The volume changes to the solution added to the red blood cells before and after the treatment to see if the amount of solution changes," would this be an effective strategy? Why or why not?
Answer:
The correct answer is No.
Explanation:
Measuring the volume change after placing:
In a hypertonic solution - solvent moves outside of the cell and the cell shrinks, the change in volume of solvent would be very minute to observe or measure as the RBCs are very small cells.
in a hypotonic solution - the change in the solvent or solute or overall solution is very less and will be very insignificant to come to any result. The water volume change would be difficult to measure.
