Definitions:

Substrate-Level

Substrate-level refers to a biochemical process that involves the direct transfer of a phosphate group from a substrate molecule to ADP to form ATP, bypassing the need for an electron transport chain.

ATP Synthesis

The process by which cells produce adenosine triphosphate (ATP), a critical energy carrier molecule, primarily in the mitochondria.

ADP

Adenosine diphosphate, a molecule involved in energy transfer within cells.

Exergonic Reaction

Chemical reaction that releases energy; opposite of endergonic reaction.
