AP BIOLOGY

Detailed explanation-1: -ATP is commonly referred to as the “energy currency” of the cell, as it provides readily releasable energy in the bond between the second and third phosphate groups.

Detailed explanation-2: -The common functional groups for ATP are hydroxyl, ether and amine.

Detailed explanation-3: -ATP is composed of an adenine ring, ribose sugar, and three phosphate groups (triphosphate). The groups of the phosphate group are usually called the alpha (), beta (), and gamma () phosphates.

Detailed explanation-4: -Functions of ATP in cells ATP plays a critical role in the transport of macromolecules such as proteins and lipids into and out of the cell. The hydrolysis of ATP provides the required energy for active transport mechanisms to carry such molecules across a concentration gradient.

Detailed explanation-5: -ATP is a nucleotide consisting of an adenine base attached to a ribose sugar, which is attached to three phosphate groups. These three phosphate groups are linked to one another by two high-energy bonds called phosphoanhydride bonds.
