Diffusion occurs because of the ________________________ of molecules.
rosijanka [135]
Diffusion occurs because of the movement of molecules from the region of higher concentration to the region of lower concentration. This movement of molecules occurs due to a thermal motion. Diffusion normally occurs between two compartments having difference in concentration. In case of fluid it moves from the region of higher concentration to the region of concentration until a balance is reached. The process of diffusion is very important for the humans as well. The oxygen that humans breathe in gets diffused with the blood.

PFK can be allosterically inhibited by ATP at high concentrations. Which of the following is the benefit of regulating glycolysi
melamori03 [73]

Answer:

The principle benefit of regulating glycolysis by the concentration of ATP is to signals the cell to stop glycolysis as sufficient amount of ATP is already present in the biological system.

Explanation:

Phosphofructokinase 1 is allosterically inhibited by ATP.Glycolysis is a catabolic as well as exergonic process which deals with the oxidation of glucose to form pyruvate along with ATP molecules.

            When ATP is present at high concentration within our body at that time there is no need to synthesize additional ATP because ATP is already present in sufficient amount.

       To maintain its own homeostasis ATP allosterically inhibit the catalytic activity of phosphofructokinase. As a result glycolysis is inhibited and the glucose molecule can be utilized in other metabolic pathways.
