Multiple Choice

What is ATP's importance in the cell?

ATP contains a long hydrocarbon tail and is important in storing energy.

ATP can add phosphate groups, thereby releasing energy that can be used in cellular processes.

ATP stores energy in carbonyl groups. When a carbonyl group is removed, energy is released to be used in cellular processes.

ATP stores the potential to react with water, thereby removing a phosphate group and releasing energy for cellular processes.

Verified step by step guidance

Understand that ATP stands for Adenosine Triphosphate, which is a molecule that carries energy within cells.

Recognize that ATP is composed of three main parts: an adenine base, a ribose sugar, and three phosphate groups.

Identify that the energy stored in ATP is primarily in the bonds between its phosphate groups, particularly the bond between the second and third phosphate group.

Learn that when ATP reacts with water (a process called hydrolysis), it loses one phosphate group, becoming ADP (Adenosine Diphosphate), and releases energy.

Conclude that this release of energy is what cells use to perform various functions, making ATP a crucial energy currency in cellular processes.
