What is the direct source of energy that powers molecular motors? A)hydrolysis of GTP B)hydrolysis of ATP C)a proton gradient D)a H⁺ gradient E)condensation of ATP

Question

Quizplus · Accepted Answer

The hydrolysis of ATP (adenosine triphosphate) is the direct source of energy that powers molecular motors. As ATP is hydrolyzed into ADP (adenosine diphosphate) and inorganic phosphate, the energy released is used by the motor to perform mechanical work. GTP (guanosine triphosphate) is also used as an energy source in some molecular motors, but ATP is the most common and predominant source. The other options (C, D, and E) are not known sources of energy for molecular motors.
