Which of the following processes releases energy to be used by a cell?

a phosphate group is added to ATP to form ADP.
a phosphate group is removed from ADP to form ATP.
a phosphate group is added to ADP to form ATP.
a phosphate group is removed from ATP to form ADP.

not sure about this question help please

HELPP

The last one.

THANK YOU!

To answer this question, we need to understand the process of ATP (adenosine triphosphate) and its conversion to ADP (adenosine diphosphate).

ATP is the main energy currency of cells, and it stores energy in the high-energy phosphate bonds. When a phosphate group is removed from ATP, it is converted to ADP, and energy is released in the process. This energy can be used by cells for various activities.

Looking at the given options, we can see that "a phosphate group is removed from ATP to form ADP" matches this description. So, the correct answer is "a phosphate group is removed from ATP to form ADP."

To summarize, ATP releases energy when a phosphate group is removed, converting it to ADP.
