Overview

Cellular processes explain how cells communicate, obtain and use energy, divide, become specialised, and move from one place to another. Cell signaling helps cells respond to specific chemical messages through receptors and ligands. Metabolic pathways show how food molecules are broken down and buil

Key Concepts

Cells respond only when they possess

Cells respond only when they possess the correct receptor for a ligand. A receptor is a protein located on the cell surface or inside the cytoplasm or

Metabolism is the use of free

Metabolism is the use of free energy by living organisms. Anabolic pathways build complex molecules from simpler ones and require energy. Catabolic pa

Glycolysis is a universal pathway

Glycolysis is a universal pathway in the cytosol. Glucose is converted into two pyruvate molecules through ten reactions. Hexokinase starts the pathwa

Pyruvate may undergo homolactic fermentation

Pyruvate may undergo homolactic fermentation to form lactate, alcoholic fermentation to form ethanol and carbon dioxide, or aerobic oxidation in mitoc

The pyruvate dehydrogenase complex is found

The pyruvate dehydrogenase complex is found only in mitochondria. It catalyses the irreversible oxidative decarboxylation of pyruvate to acetyl CoA, r
