Most energy-requiring reactions in the cell obtain their energy from
A) The hydrolysis of the terminal phosphate bond in ATP
B) Thermal energy provided by the heat of the body
C) The energy in the chemical bonds of proteins
D) Proteolys is
E) Glycogenolysis

Question

Quizplus · Accepted Answer

The hydrolysis of the terminal phosphate bond in ATP is the primary source of energy for most energy-requiring reactions in cells. ATP (adenosine triphosphate) acts as a universal energy currency, and its breakdown into ADP (adenosine diphosphate) and an inorganic phosphate releases energy that can be used to drive various cellular processes.
