The process by which cells break down organic molecules, such as glucose, to produce ATP (adenosine triphosphate), the primary energy currency of cells.
Cellular Respiration
Occurs in the presence of oxygen. It involves a complete breakdown of glucose to produce a larger amount of ATP. Also includes the stages of glycolysis, the citric acid cycle, and the electron transport chain.
Aerobic Respiration
Occurs in the absence of oxygen. It involves an incomplete breakdown of glucose to produce a smaller amount of ATP. Also includes only the glycolysis stage, without the citric acid cycle and electron transport chain
Anaerobic Respiration
The first stage of cellular respiration. It occurs in the cytoplasm of the cell. It also Breaks down glucose into pyruvate molecules and produces a small amount of ATP.
Glycolysis
Occurs in the mitochondria. It further breaks down the pyruvate molecules from glycolysis. Produces additional ATP, as well as NADH and FADH2 electron carriers.
Krebs Cycle
The process of generating ATP using the electron transport chain and chemiomosis.
Oxidative Phosphorylation and Electron Transport Chain
