Hold cell together, controls what goes in and out of cells 2 of 27 Where are enzymes need for respiration found? Mitochondria 3 of 27 What 3 extra things do plants cells have? Cell Wall, Vacuole and Chloroplasts 4 of 27 What do chloroplasts contain? Chlorophyll and enzymes for photosynthesis 5 of 27 Name all 5 parts of yeast cell Cell Membrane; Cytoplasm; Nucleus; Mitochondria; Cell Wall 6 of 27 What do bacteria cells have instead of a nucleus? Circular molecule of DNA 7 of 27 Can bacteria respire aerobically? Yes, despite not having mitochondria 8 of 27 What are enzymes? Enzymes are proteins that speed up chemical recations 9 of 27 Where do substrates join onto enzymes? Active Site 10 of 27 What happens if enzymes have the wrong temperature or pH? The active sight denatures 11 of 27 What does optimum mean? When enzymes are most active 12 of 27 Define respiration A series of chemical reactions that release energy by breaking down large food molecules 13 of 27 What is the energy released in respiration used for? Movement, active transport, synthesis of large molecules 14 of 27 Do you need oxygen if it is anaerobic respiration? No 15 of 27 What is the equation for aerobic respiration? Glucose+Oxygen-Carbon dioxide+water (+energy) 16 of 27 What is the word equation of anaerobic respiration in animal cells? Glucose-Lactic acid (+energy) 17 of 27 What is the word equation of anaerobic respiration in plant cells and yeast cells? Glucose-Ethanol+Carbon dioxide (+energy) 18 of 27 What is fermentation? When microorganisms break down sugars 19 of 27 What are 3 ways we use fermentation? Bio-gas, Bread and Alcohol making 20 of 27 Define photosynthesis A series of chemical reactions that use energy form sunlight to produce food 21 of 27 Why is chlorophyll needed? It absorbs sunlight and allows energy to be used to convert carbon dioxide and water 22 of 27 What is the word equation for photosynthesis? Carbon dioxide+water-glucose+oxygen 23 of 27 What are three main ways plants use glucose? Respiration, make chemical for growth and stored as starch 24 of 27 What three factors effect photosynthesis? Light, temperature and CO2 levels 25 of 27 What is a limiting factor? A factor that stops photosynthesis from happening any faster 26 of 27 3 ways to collect data on photosynthesis? Light meter, Quadrat and Identification Key 27 of 27
