Verified step by step guidance

Understand the role of functional groups in biochemical reactions. Functional groups are specific groups of atoms within molecules that have characteristic properties and reactivity.

Recognize that the phosphate group is known for its ability to store and release energy, particularly in the form of ATP (adenosine triphosphate) in cellular processes.

Learn that when a phosphate group is removed from a molecule, such as ATP, through a hydrolysis reaction (reaction with water), energy is released. This is a key process in cellular energy transfer.

Identify the chemical structure of a phosphate group, which typically consists of a phosphorus atom bonded to four oxygen atoms. This structure is often represented as PO₄³⁻.

Understand that the removal of a phosphate group from a carbon skeleton, such as in the conversion of ATP to ADP (adenosine diphosphate), involves breaking a high-energy bond, which results in the release of energy that can be used by the cell.
