Cofactors and coenzymes. Reversible, irreversible, competitive, and noncompetitive inhibitors. Allosteric enzymes. Feedback inhibition.
The citric acid cycle, always active to varying degrees, is crucial for ATP production. Acetyl-CoA enters the cycle, undergoes oxidations, and exits as carbon dioxide, producing FADH2 and NADH. This cycle is regulated through allosteric regulation and substrate availability, responding swiftly to the cell's energy needs.

Glycolysis is the first step in the breakdown of glucose to extract energy for cellular metabolism. Glycolysis consists of an energy-requiring phase followed by an energy-releasing phase.
The pentose phosphate pathway is an important metabolic process that generates NADPH and ribose-5-phosphate for various cellular functions.
