Intro to Cellular Respiration

Cellular Respiration Most of the foods we eat contain usable energy stored in proteins, carbohydrates, and fats. Before this energy can be used it must be transferred to ATP

C6H12O6 + 6 O2  6 CO2 + 6 H2O + ATP energy Cellular Respiration Cellular respiration is the process by which cells release the energy from food to make ATP. Formula: C6H12O6 + 6 O2  6 CO2 + 6 H2O + ATP energy

Two Stages of Cell Respiration: Stage One: Glucose is broken down and converted to pyruvate, producing a small amount of ATP and NADPH. Glycolysis

Two Stages of Cell Respiration: Stage Two: Aerobic (O2) respiration: pyruvate and NADH are used to make a large amount of ATP. Krebs cycle and electron transport chain Anaerobic (no O2) respiration: pyruvate is converted to lactate or ethanol and carbon dioxide. Fermentation
