AP BIOLOGY

Detailed explanation-1: -ATP is able to power cellular processes by transferring a phosphate group to another molecule (a process called phosphorylation). This transfer is carried out by special enzymes that couple the release of energy from ATP to cellular activities that require energy.

Detailed explanation-2: -ATP involves phosphorylation, where the Pi released on ATP hydrolysis is transferred to a reactant molecule. The phosphate group covalently binds to the reactant molecule and is called phosphorylated intermediate. The phosphorylated molecule has a higher energy level than its unphosphorylated form.

Detailed explanation-3: -provides the majority of energy for ATP synthesis in a cell. When ATP is used as an energy source, a phosphate group is removed by hydrolysis.

Detailed explanation-4: -The process of adding a phosphate group taken from ATP to another molecule to energize it is called phosphorylation. ATP has very high-energy phosphate groups, and these groups can be removed and given to other molecules as needed.

Detailed explanation-5: -When ATP transfers a phosphate group to a target molecule, how might the target molecule change? (Select all that apply). The target molecule changes shape and the target molecule becomes more likely to bond with other molecules.
