Question

A high-energy bond in ATP is present

A) between adenine and ribose.
B) between adenine and a phosphate group.
C) between the first and second phosphate group.
D) between the second and third phosphate group.
E) both C and D

Answer 1

The high-energy bond in ATP is present between the second and third phosphate groups (beta and gamma), making it the greatest source of energy in a cell. Catabolic enzymes break this bond to release energy for cellular work.

Step-by-step explanation:

Adenosine triphosphate, or ATP, is a molecule that carries energy within cells. It is often referred to as the "energy currency" of the cell because it provides the energy needed for various cellular processes.

The high-energy bond in ATP is present between the second and third phosphate groups (beta and gamma). This bond is the greatest source of energy in a cell and is broken by catabolic enzymes to release energy for cellular work.
