Substrate-level phosphorylation

Campbell's Biology, 9e (Reece et al.) Chapter 9 Cellular Respiration and Fermentation This is one of the most challenging chapters for students to master. Many students become overwhelmed and confused by the complexity of the pathways, with the multitude of intermediate compounds, enzymes, and processes. The vast majority of the questions in this chapter address central concepts rather than details of these pathways. Other questions have accompanying figures that provide details for reference and ask students to interpret or use these models. Overall, the emphases are on the inputs and outputs of each pathway, the relationships among these pathways, the cellular locations, redox as a central principle in respiration, and chemiosmosis.

Carbohydrate catabolism

metabolism

Cellular Respiration Plant cells harvest energy from the sun, and store it as glucose. That glucose must be transformed into energy the cell can use, specifically ATP. This takes place in the mitochondria of cells. There are two ways that a cell can harvest energy from the food (glucose) it takes in: Anaerobic Cell Respiration (Fermentation) ? glucose metabolism in the absence of oxygen that produces 2ATP molecules and either ethanol or lactic acid. Involves 2 stages: Glycolysis Fermentation Aerobic Cellular Respiration ? glucose metabolism with oxygen that produces 36 ATP molecules, CO2 and H2O. Involves 4 stages: Glycolysis Pyruvate oxidation Krebs cycle Electron transport and chemiosmosis Stage 1 ? Glycolysis
