Definitions:

Glycolysis

Glycolysis is the metabolic pathway that breaks down glucose into pyruvate, generating ATP and NADH as energy sources for the cell, occurring in the cytoplasm of cells.

NADH Molecules

Nicotinamide adenine dinucleotide (NAD) plus hydrogen (H), an important coenzyme in the body that plays a key role in the energy production process within cells through redox reactions.

Pyruvate Molecules

Organic compounds that play a pivotal role in energy production pathways, such as glycolysis and the Krebs cycle, within cells.

Acetyl CoA

A central metabolic molecule that signifies the convergence point of several metabolic pathways, crucial in energy production.
