Through which conversion is energy released?a) ADP to ATP
b) ATP to ADP
c) NADP+ to NADPH
d) CO2 and H2O to C6H12O6 and O2

Answers

Answer: B) ATP to ADP

This reaction is termed as ATP hydrolysis.

ATP ( adenosine triphosphate) conversion to ADP ( adenosine diphosphate) is an energy producing reaction ( exothermic reaction). ATP contains high energy bonds called phosphoanhydride bonds. Thus, when this bond is broken down, ATP is converted to ADP and Pi ( inorganic phosphate) and releases large amount of energy.

The answer is b) ATP to ADP. This is a method for our body to provide energy for reactions. While other three forms are energy absorbing which can conserve energy for our body.
