Detailed explanation-1: -Energy from ATP is used to fuel all manner of chemical reactions, including those required for copying DNA and building proteins. In these reactions, enzymes oversee the transfer of energy from ATP hydrolysis to the formation of another chemical bond.
Detailed explanation-2: -Answer and Explanation: The statement about ATP (adenosine triphosphate) that is correct is e. The cycling between ATP and ADP + Pi provides an energy coupling between catabolic and anabolic pathways. Catabolic pathways of this reaction provide the necessary energy required for the formation of ATP from ADP and Pi.
Detailed explanation-3: -The phosphate tail of ATP is the actual power source which the cell taps. Available energy is contained in the bonds between the phosphates and is released when they are broken, which occurs through the addition of a water molecule (a process called hydrolysis).
Detailed explanation-4: -Energy is released when an ATP is broken down into ADP and phosphate (a is correct). ATP is the primary energy currency of the cell. This means that cellular processes that require an energy input rely on the energy released from ATP hydrolysis.
