Question

If ATP hydrolysis to release energy is inhibited, how would this impact transport across the cell membrane?

Oxygen would not be able to cross the membrane.
Aquaporins would inhibit water from crossing into the membrane.
Solutes would not be able to move against the concentration gradient.
Facilitated diffusion of ions would not be able to cross the membrane.

Answer 1

Solutes would not be able to move against the concentration gradient.

Step-by-step explanation:

Certain substances move from a region of low concentration to high concentration across a membrane. This movement is said to occur against the concentration gradient, hence, it requires energy in form of ATP to occur. This form of transport is called ACTIVE TRANSPORT.

In a case where ATP hydrolysis (break of phophoanhydride bonds) to release energy is inhibited, there would be no energy (ATP) to perform active transport. Therefore, solutes would not be able to move against the concentration gradient.
