Question

Energy is released to be used by a cell when a phosphate group is
removed from ADP to form ATP
added to ADP to form ATP
removed from ATP to form ADP
added to ATP to form ADP

Answer 1

Answer:

Energy is released to be used by a cell when a phosphate group is removed from ATP to form ADP.

Explanation:

Hello,

Adenosine diphosphate (ADP) is an important organic compound with a chemical formula C₁₀H₁₅N₅O₁₀P₂. It helps in metabolic activities and facilitates energy flow in living cells. The adenine in ADP combines with sugar molecules to form adenosine that can accept a phosphate group, upto 3 of them.

ATP is adenosine 5' triphosphate. This molecule is primary energy carrier in living organisms as it stores and transfer energy to living cells.Those in living things, both ATP and ADP store and release energy, more energy is in ATP than ADP.

During hydrolysis, a phosphate group is removed through the breakdown of high-energy bonds called phosphoanhydride bonds and energy is given out as ATP coverts to ADP.

So, the correct answer is the third option.

Answer 2

Answer:

The correct answer is the c = removed from ATP to form ADP

Explanation:

Hello ! Let's solve this!

It is a catabolic process where energy is released and formed from a complex molecule, simpler molecules. In this case, to release energy, ATP (adenosine triphosphate) removes a phosphate group to form ADP (adenosine diphosphate).

The correct answer is the c = removed from ATP to form ADP
