Which of the following can combine in a cell to convert a lower-energy molecule into a higher-energy molecule?

a.) adp + p + energy
b.) atp + p + energy
c.) adp + p
d.) atp + p

The correct option is A.

In the living cells, the only type of energy that the cells can use for their life sustaining activities is ATP [Adenosine Tri Phosphate]. ATP molecules are usually formed during the process of cellular respiration. ADP [Adenosine Tri Phosphate] is a low energy molecule in the living cells, which can easily be converted to ATP, this is done by combing a single molecule of phosphate to ADP in order to produce ATP. Thus, ADP + P + Energy = ATP.

i believe the answer is c. "baking" is the gerund, while "baking blueberry muffins" would be the gerund phrase. hope this ! : )
