9.1: Catabolic pathways yield energy by oxidizing organic fuels. Redox reactions: oxidation and reduction. The stages of cellular respiration. In redox reactions the loss of e- from one substance is called oxidation. The gain to the other is known as reduction. The harvesting of energy from glucose by cellular respiration is a cumulative function of three metabolic stages: Catabolic pathways and production of ATP Organic compounds possess potential energy because of the arrangement of electrons in bonds between atoms. Compounds that participate in exergonic reactions can act as fuel. Enzymes help cells degrade complex organic molecules that are rich in potential energy. This breakdown can provide energy to

Breanna Takacs AP Biology A2 11/27/12 Cellular Respiration Free Response Questions The Krebs Cycle and oxidative phosphorylation are both processes involved in obtaining ATP from pyruvate, the end product of glycolysis. Before the Krebs Cycle actually begins, pyruvate combines with coenzyme A to produce acetyl CoA. One NADH and one CO2 are produced. Then the Krebs Cycle begins when citrate is formed by combining acetyl CoA with OAA. 3NADH, 1 FADH2 are made and CO2 is released. It is possible for the Krebs Cycle to be a cycle because the last product is OAA which reacts with acetyl CoA.

Acetyl CoA ? the product of the transition reaction between glycolysis and the Krebs cycle, pyruvate is oxidized to Acetyl-CoA by NAD+ , also producing CO2, and NADH Aerobic ? Requiring free oxygen: any biological process that can occur in the presence of gaseous oxygen. Alcohol Fermentation ? The process by which yeast turns sugar into carbon dioxideCO2) and alcohol. Anaerobic ? Any process that can occur without oxygen, such as anaerobic fermentation or H2S photosynthesis. ATP Synthase ? An enzyme that catalyzes the formation of ATP from the phosphorylation of ADP with inorganic phosphate, using a form of energy, such as the energy from a proton gradient.

Chapter 9 notes Cellular Respiration: Harvesting Chemical Energy Concept 9.1 Metabolic pathways that release energy are called catabolic pathways - fermentation and cellular respiration _____________: partial degradation of sugars that occurs w/out the help of O2 ________: O2 is consumed as a reactant along w/ the sugar - more efficient Concept 9.1 Cellular respiration occurs in the _______________ Organic + O2 ? Carbon + H2O + Energy compounds dioxide C6H12O6 + 6O2 ? 6CO2 + 6H2O + Energy 1 glucose = -686 kcals Concept 9.1 ATP is the central molecule responsible for energy used by the cell The cell uses enzymes to transfer phosphate groups from ATP to other compounds (making them _________________) ATP ?

Cellular Respiration Wednesday, March 06, 2013 5:23 PM ? Cellular Respiration Cellular respiration - an ATP-generating process that occurs within cells; energy is extracted from energy-rich glucose to form ATP from ADP and phosphate C6H12O6 + 6O2 -> 6CO2 + 6H2O + energy Glucose + air = carbon dioxide + water + energy Aerobic respiration - cellular respiration in the presence of O2; divided into three components: glycolysis, the Krebs cycle, and oxidative phosphorylation ? Glycolysis Glycolysis - the decomposition (lysis) of glucose (glyco) to pyruvate (or pyruvic acid); nine intermediate products are formed and, of course, each one is catalyzed by an enzyme; in six of the steps, magnesium ions are cofactors that promote enzyme activity; summary of the steps:
