  1. Enzymes What type of cell is this? Where is it found? How is it adapted to it job? Draw a graph to show what happens to enzyme activity as temperature increases? activity What are enzymes? What do we call the model that is used to explain how enzymes work? temperature What happens to enzymes at high temperatures? • What is the function of: • cell wall • Nucleus • Cell membrane • Chloroplast • cytoplasm Why do we need enzymes? Give some examples of processes that are controlled by enzymes. B4 Revision – Life Processes Part 1 Osmosis time How are diffusion and active transport different? What is diffusion? How are osmosis and diffusion different? partially permeable membrane What is active transport? What is a partially permeable membrane? Name 3 things that move in or out of cells: What is osmosis?

  2. ________ respiration can take place in animal, plant and some microbial cells in conditions of low ________ or absence of _________ e.g. • Roots in waterlogged soil • Bacteria in puncture wounds • Human cells during vigorous exercise • What is the energy produced in respiration used for? • Which is more efficient, aerobic or anaerobic respiration? Draw and label a plant cell and an animal cell What is the word/symbol equation for aerobic respiration? What is the word/symbol equation for photosynthesis? B4 Revision – Life Processes Part 2 What are the tests for starch and glucose? Starch: Glucose: • Glucose is produced during photosynthesis. What does the plant use glucose for? • What three factors can limit the rate of photosynthesis? Equations for anaerobic respiration In animal cells: Glucose _______ acid (+energy released) In plant cells and some microorganisms: Glucose _______ + carbon dioxide (+ energy released) How can anaerobic respiration of microorganisms be useful?
