Endothermic (takes heat in) 1 of 14 What is the word equation for photosynthesis? carbon dioxide + water ----- glucose + oxygen 2 of 14 What are the factors affecting photosynthesis? Temperature, light and carbon dioxide concentration 3 of 14 What other products is glucose changed into? Insoluble starch, fat or oil, cellulose, proteins and amino acids 4 of 14 Is respiration an endothermic or exothermic reaction? Exothermic (releases energy) 5 of 14 What is the energy released by respiration used for? Movement, active transport, keeping warm and to make large molecules. 6 of 14 Where does respiration take place? It happens continuosly in living cells in the mitochondria. 7 of 14 Is respiration anaerobic or aerobic respiration? Both. It can be aerobic (with oxygen) or anaerobic (without oxygen) 8 of 14 What is the word equation fro aerbic respiration? Oxygen + glucose ----- carbon dioxide + water 9 of 14 How much energy is released in anaerobic respiration compared to aerobic? The glucose is not completely broken down meaning it transfers much less energy than aerobic respiration 10 of 14 What is the word equation for anaerobic respiration in animals? glucose ----- lactic acid 11 of 14 What is the word equation for anaerbic respiration in plant and yeast cells? glucose ----- ethanol + carbon dioxide 12 of 14 What is anaerobic respiration in yeast cells called? Fermentation and it has economic importance in the manufacture of bread and alcoholic drinks. 13 of 14 What is oxygen debt? The amount of extra oxygen the body needs after excerise to react with the lactic acid and remove it from the cells. 14 of 14
