B4 Revision – Bioenergetics (page 42-45 in revision guide) What is the green pigment needed for photosynthesis? List three factors that may limit the rate of photosynthesis. State the word equation for anaerobic respiration in animals. State the word equation for anaerobic respiration in plants and yeast. What does a plant need glucose for? What is meant by an ‘exothermic’ reaction? Which type of respiration requires oxygen? What is fermentation? The energy transferred by respiration can be used to make what? List three. KEY WORDS: Photosynthesis Endothermic Exothermic Limiting factor Aerobic respiration Anaerobic respiration Fermentation Lactic acid Oxygen debt Metabolism
