Respiration and Fermentation Study Notes

Substrate

A reactant molecule that specifically binds to an enzyme's active site.

Active Site

The specific region on an enzyme where a substrate attaches during a reaction.

Primary Purpose of Food

To serve as a source of chemical energy that is ultimately utilized to produce ATP.

Lipids

The organic molecules with the highest energy potential compared to carbohydrates and proteins.

Aerobic Respiration

A cellular process that uses oxygen to break down glucose into $CO_2$, water, and ATP.

Anaerobic Respiration

A process that generates ATP from glucose or other nutrients without using oxygen, utilizing alternative electron acceptors.

Synthase

The enzyme responsible for synthesizing ATP.

Location of Glycolysis

Occurs in the cytoplasm or cytosol of the cell.

Location of Citric Acid Cycle

Occurs in the mitochondrial matrix.
