If atp breakdown (hydrolysis) is inhibited, which of the following types of movement across cell membranes is also inhibited?

a) movement of oxygen into a cell

b) movement of water through aquaporins

c) facilitated diffusion

d) passage of a solute against its concentration gradient

d) passage of a solute against its concentration gradient

Explanation:

When a solute is transported against its concentration gradient, the cells use metabolic energy. To move a substance from the region of its lower concentration to that of its higher concentration, the energy of ATP hydrolysis is utilized. These types of transport mechanisms are called active transports. If ATP hydrolysis is inhibited in a cell, it would not be able to perform the uphill movement of solutes due to the lack of any source of energy to drive the process.
