Solution
ATP (Adenosine Triphosphate) releases energy that can be used by a living cell through the process of breaking a bond within an ATP molecule. Here's a step-by-step explanation:
-
ATP is composed of an adenine base, a ribose sugar, and three phosphate groups. The bond holding the second and third phosphate group is a high-energy bond.
-
When a cell needs energy, this high-energy bond is broken in a process called hydrolysis.
-
Hydrolysis of ATP involves the addition of a water molecule, breaking the phosphate bond and releasing energy. This transforms ATP into ADP (Adenosine Diphosphate) and a free phosphate group.
-
The energy released from this process is then used by the cell to carry out various functions such as movement, synthesis of proteins, and transportation of molecules across cell membranes.
-
The ADP and free phosphate can be recombined, or "recharged," through the process of cellular respiration to form ATP again, ready to release energy when the cell needs it.
So, the correct answer to your question is: "By breaking a bond within an ATP molecule".
