Electron Carriers Overview

Electron carriers, such as NADH, FADH2, and NADPH, are molecules that transport electrons during cellular respiration and photosynthesis, facilitating the transfer of energy within biological systems. They play crucial roles in redox reactions, helping to convert energy from nutrients into usable forms for cellular processes.

Key Terms

NADH
A reduced form of nicotinamide adenine dinucleotide, acting as an electron carrier.

Example: NADH is produced during glycolysis.

FADH2
A reduced form of flavin adenine dinucleotide, serving as an electron carrier.

Example: FADH2 is generated in the Krebs cycle.

NADPH
A reduced form of nicotinamide adenine dinucleotide phosphate, used in anabolic reactions.

Example: NADPH is essential for fatty acid synthesis.

Electron Transport Chain
A series of protein complexes that transfer electrons to produce ATP.

Example: The electron transport chain is located in the mitochondria.

Oxidation
The loss of electrons from a molecule.

Example: Glucose undergoes oxidation during cellular respiration.

Reduction
The gain of electrons by a molecule.

Example: NAD+ is reduced to NADH.
