Study Notes

Citric Acid Cycle

The citric acid cycle is also known as the Krebs cycle or tricarboxylic acid (TCA) cycle.
The main purpose of the citric acid cycle is to generate energy for the cell through the breakdown of carbohydrates, fats, and proteins.

Cellular Respiration

The citric acid cycle is used in aerobic respiration to generate energy.

Precursors and Metabolites

The citric acid cycle provides precursors for the synthesis of amino acids, choline, and other biomolecules.
It is not necessary for metabolites to follow only one specific route in the citric acid cycle, as the cycle is flexible and can accommodate different metabolic pathways.
