Question

question 1 - 8 isabella wants to determine whether a homeostatic process requires energy to proceed. which characteristic should she look for? a reaction that is coupled to the hydrolysis of atp a reaction that is coupled to the production of atp movement of a substance across a membrane with a gradient movement of a substance across a membrane in both directions

Explanation:

Hydrolysis of ATP releases energy. A reaction coupled to ATP hydrolysis is likely to be exergonic and may not necessarily indicate that the homeostatic process itself requires energy input. Production of ATP often occurs in energy - releasing processes. Movement of a substance across a membrane with a gradient is a passive process that does not require energy. Movement of a substance across a membrane against a gradient requires energy for active transport, which is related to homeostatic processes needing energy. But among the given options, a reaction coupled to the hydrolysis of ATP (which provides energy) is a sign that the homeostatic process may require energy to proceed.

Answer:

A. a reaction that is coupled to the hydrolysis of ATP
