Question

the model shows how glucose is converted into energy for use by the muscles of the human body. which statement interprets the model correctly? energy is released when atp and adp combine energy is released when a phosphate group attaches to adp a useable, high - energy molecule is generated when a phosphate group is released a useable, high - energy molecule is generated when a phosphate group attaches to adp

Explanation:

ADP (adenosine diphosphate) can combine with a phosphate group to form ATP (adenosine - triphosphate), which is a high - energy molecule usable by cells. Energy is required to attach a phosphate group to ADP, and energy is released when the phosphate group is removed from ATP. The first two options are incorrect as energy is not released in those processes. The third option is wrong because releasing a phosphate group from ATP releases energy rather than generating a high - energy molecule. When a phosphate group attaches to ADP, ATP is formed, which is a useable, high - energy molecule.

Answer:

A useable, high - energy molecule is generated when a phosphate group attaches to ADP.
