Cellular Respiration In photosynthesis sunlight re-arranges atoms of CO2 and H2O to produce glucose and O2 In cellular respiration, O2 is consumed as glucose is broken down into CO2 and H2O; the cell then gets the energy released in ATP o Energy is lost as heat o Chemicals are recycled CO2 and H2O released in cellular respiration are converted through photosynthesis to glucose and O2 and used in respiration Four Stages of Cellular Respiration o Glycolysis: Occurs in cytoplasm (outside of the organelles) Breaks down glucose into two molecules of a 3-carbon compound called pyruvate Start with glucose and add 2 ATP’s end with 4 ATP’s glucose splits into 2,

Unformatted text preview: each gain 1 NAD o Oxidation of Pyruvate: Occurs in mitochondria o Citric acid cycle Occurs in mitochondria Completes breakdown of glucose by decomposing pyruvate to CO2 Stages 1,2,3 create a small amount of ATP, main function is to supply the 4 th stage with electrons o Oxidative phosphorylation: NADH gives off its electrons and generates low energy NAD+ The DADH goes through many reactions until they produce H2O Protons stay in the inter-membrane and can only move through the synthase...
