What is another name for the citric acid cycle?

The citric acid cycle is also known as the Krebs cycle. It's a series of chemical reactions that occur in the mitochondria of cells.

What is the primary function of the citric acid cycle?

The main purpose of the citric acid cycle is to generate energy (ATP) from the breakdown of acetyl-CoA, a molecule derived from carbohydrates, fats, and proteins.

Which type of respiration uses the citric acid cycle?

Aerobic respiration is the process of generating energy using oxygen. The citric acid cycle is a crucial step in aerobic respiration.

What are some products of the citric acid cycle?

The citric acid cycle produces important building blocks for other molecules, including amino acids.

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.
