Of the following groups—adenine, ribose, and phosphate—which are changed during the processes that convert among atp, adp, and amp? which group or groups does not change?

Answers:

The correct answer is "adenine and ribose do not change, while phosphate changes".

Explanation:

Adenosine triphosphate (ATP), adenosine diphosphate (ADP) and adenosine monophosphate (AMP) are three molecules of biological importance, for their role in metabolic and synthetic pathways. The three molecules have a backbone made of adenine and ribose which remains unchanged. In the processes that convert among ATP, ADP and AMP the only group that changes among them is the number of phosphates. Actually, the number of phosphates is what gives these molecules their name: ATP has three phosphate groups, ADP has two and AMP just one.

well we can't tell you because we cant see the time give a screen shot or something.
