Concentration of CO2 Temperature - Optimum temperatures needed. Enzymes - Can get denatured at unsuitable temperatures. Cellular Respiration & Photosynthesis: Photosynthesis - 6CO2 + 6H2O sunlight C6H12O6+ 6O2. Captures energy in the chloroplast. Cellular Respiration - C6H12O6 + 6O2 enzymes 6CO2 + 6H20 + ATP in Mitochondria Photosynthesis Absorption of light energy Conversion of light energy Storage of energy Cellular respiration Stages: a) Glycolysis Conversion of glucose to pyruvates, Production of 2 ATP b) Kreb’s cycle 2 ATP and NADH & FADH2 – c) Electron transport chain -34 ATP
