KEY CONCEPT
Cellular respiration is an aerobic process with two main stages.
Glycolysis is needed for cellular respiration.
- The products of glycolysis enter cellular respiration when oxygen is available. - ATP molecules are used to split glucose - ATP molecules are produced - molecules of NADH produced - two molecules o f pyruvate produced
The Krebs cycle is the first main part of cellular respiration.
- Pyruvate is broken down before the Krebs cycle. - carbon dioxide released - NADH produced
- The Krebs cycle produces energy-carrying molecules.

Do the Interactive reader Question and Text Book Questions Reviewing > Main Ideas 1.What is the role of pyruvate in cellular respiration? Pyruvate, produced by the breakdown of glucose, is needed for the Krebs cycle which is a part of cellular respiration. 1.Describe in your own words the function of the Krebs cycle. The Krebs cycle breaks down and extracts energy form carbon-based molecules transfers it to the Electrons transport chain, makes a small amount of ATP, and releases carbon dioxide. 1.Explain the functions of electrons hydrogen ions, and oxygen in the electron transport chain. The electron transport chain pumps hydrogen ions across the inner mitochondrial membrane. Hydrogen ions then flow through a channel that is bound to ATP syntheses. Oxygen picks up electrons and hydrogen ions so that the electron transport chain can continue to function.
