Cellular Respiration and Fermentation Overview

Cellular aerobic respiration

Process through which cells in living organisms break down glucose and other organic molecules to produce energy in the form of ATP.

Glycolysis

Biochemical pathway in which glucose molecule is broken down into 2 molecules of pyruvate (pyruvic acid).

Krebs cycle

Occurs in the mitochondrial matrix and generates: 2 CO2, 3 NADH, 1 FADH2, 1 ATP.

Electron transport chain

Located on the inner mitochondrial membrane, it facilitates the production of ATP using the energy from electron transfer.

ATP Synthase

The ETC facilitates the production of ATP using the energy from electron transfer.

Final Electron Acceptor

Oxygen acts as the 'clean up crew', combining with electrons and hydrogen ions to form water.

glucose compound

c6h12o6

ATP

Main energy carrying molecule in the body.

Mitochondria

The 'powerhouses of the cell,' primarily responsible for generating energy in the form of ATP.

Pyruvic acid

3 carbon compounds that are the end product of glycolysis; 1 glucose equals 2 pyruvic acid.

NADH

Energy carrier molecule that speeds up chemical reactions

FADH2

A molecule that carries energy to create ATP in cells.

Acetyl CoA

Compound that comes together with oxaloacetic acid and pyruvate, plays a major role in metabolism.

Oxaloacetic acid

A four-carbon compound of Krebs cycle that combines with acetyl CoA to form citric acid.

Fermentation

An anaerobic process that breaks down sugars into simpler compounds.

Lactic acid fermentation

Occurs in your muscle cells, produces lactic acid, results in muscle fatigue and cramps.

Alcoholic fermentation

Produces alcohol (ethyl) and carbon dioxide.
