The release of energy from food and it occurs in all living cells. 1 of 11 What does respiration provide to living things? Energy for chemical reactions, growth and movement 2 of 11 What does photosynthesis use? The Sun's energy and makes food and energy available to food chains 3 of 11 The equation for photosynthesis is: Carbon dioxide + water ---(light energy)---> glucose + oxygen 4 of 11 The symbol equation for photosynthesis: 6CO2 + 6H2O ---(light energy)--->C6H1206 + 6O2 5 of 11 The equation for Aerobic respiration is: Glucose + oxygen --> carbon dioxide + water (+energy released) 6 of 11 The symbol equation for Aerobic respiration is: C6H1206 + 6O2 ---> 6CO2 + 6H2O (+energy released) 7 of 11 The equation of Anaerobic respiration in animal cells and some bacteria: Glucose -----> lactic acid (+energy released) 8 of 11 The equation of Anaerobic respiration in plant cells and some microorganisms including yeast is: Glucose ------> ethanol + carbon dioxide (+energy released) 9 of 11 What are enzymes? Biological catalyst that speeds up chemical reactions 10 of 11 What do enzymes work best at? Their optimum temp. and pH 11 of 11
