Unformatted text preview: Cellular Respiration I. Reaction: C 6 H 12 O 6 + 6O 2 + 6H 2 O ——> 6CO 2 + 12 H 2 O + energy (38 ATP and heat) II. Aerobic Cellular Respiration occurs in three stages. A. Glycolysis (occurs in the cytoplasm) 1. One glucose is split into two pyruvates (C 3 H 4 O 3 ). 2. 4 ATP are produced, but 2 endergonic reactions use up 2 ATP. 3. Glycolysis requires no oxygen, and occurs whether oxygen is present or not. 4. Glycolysis occurs in all living cells. 5. Fermentation follows glycolysis in anaerobic conditions. a. Fermentation is not part of aerobic cellular respiration. b. Fermentation occurs in the cytoplasm. c. The purpose of fermentation is to prevent the accumulation of pyruvate, and to prevent the depletion of the NAD ox pool. d. There is more than one kind of fermentation. B. Krebs Cycle (occurs in the matrix of the mitochondria) 1. The Krebs cycle follows glycolysis in aerobic conditions (if the cell is capable of aerobic respiration).The Krebs cycle follows glycolysis in aerobic conditions (if the cell is capable of aerobic respiration)....
