Definitions:

Free Radicals

Highly reactive molecules with unpaired electrons that can cause damage to cells and DNA, playing a role in aging and various diseases.

Aerobic Respiration

Oxygen-requiring cellular respiration; breaks down organic molecules (particularly glucose) and produces ATP, carbon dioxide, and water. Includes glycolysis, acetyl–CoA formation, the Krebs cycle, and electron transfer phosphorylation.

Electron Transfer Chains

Biological pathways through which electrons are transferred from electron donors to electron acceptors, playing a crucial role in cellular respiration and photosynthesis.

NADH

Nicotinamide adenine dinucleotide (NADH) is a coenzyme involved in redox reactions, carrying electrons from one reaction to another in cellular respiration.
