Cellular respiration is the process of oxidizing food molecules, like glucose, to carbon dioxide and water. The energy released is trapped in the form of ATP for use by all the energy-consuming activities of the cell.
There are two types of cell respiration: Aerobic respiration and Anaerobic Respiration

GLYCOLYSIS:
Process in which Glucose, which is a 6 carbon molecule, is broken down into two pyruvate (3 carbon molecule)
Yield: Small amounts of ATP

AEROBIC RESPIRATION
- Aerobic cell respiration: requires oxygen and gives a large yield of ATP from glucose. This respiration continues its reactions in the mitochondria of the cell
- Aerobic cell respiration: requires oxygen and gives a large yield of ATP from glucose. This respiration continues its reactions in the mitochondria of the cell
- Pyruvate from diffuse from the cytosol into the mitochondrial matrix
- Series of reactions (link reaction, Krebs cycle, electron transport system, oxidative phosphorylation) oxidizes pyruvate to produce ATP
- Yield: LOTS of ATP (36 or more)
- Waste: Water and CO2
ANAEROBIC RESPIRATION
- Anaerobic cell respiration: gives a small yield of ATP from glucose and does not use oxygen. The end product lactase in animals and ethanol in yeast
