Study Notes
Overview of Cellular Respiration
- Cellular respiration is the first step in the breakdown of glucose
- The process occurs in the cytoplasm and mitochondria
Glycolysis
- Glycolysis is the first stage of cellular respiration
- It occurs in the cytoplasm
- The net gain of ATP molecules in glycolysis is 2
- Glucose is the starting molecule for glycolysis
- Pyruvate is the final product of glycolysis
- NAD+ gets reduced to NADH during glycolysis
- 2 NADH molecules are produced from one glucose molecule during glycolysis
- CO2 is not produced during glycolysis
Krebs Cycle
- The Krebs cycle takes place in the mitochondrial matrix
- The Krebs cycle produces ATP, NADH, and FADH2
- Acetyl-CoA enters the Krebs cycle
- Oxaloacetate is regenerated at the end of the Krebs cycle
- CO2 is produced during the Krebs cycle
Electron Transport Chain
- The electron transport chain is the main purpose of generating ATP
- Oxygen is the final electron acceptor in the electron transport chain
- The electron transport chain produces the most ATP in cellular respiration
- ATP synthase is the crucial enzyme for ATP synthesis in the electron transport chain
- 3 ATP molecules are generated per NADH during the electron transport chain
General Concepts
- In aerobic respiration, the energy in glucose is captured as ATP
- Fermentation is the pathway taken when oxygen is not present in sufficient amounts for cellular respiration
- Carbon dioxide is released as a waste product during cellular respiration
- The majority of ATP is produced during cellular respiration in the mitochondrial inner membrane
- Oxygen plays a crucial role in cellular respiration as the final electron acceptor
