Absorbs the sunlight and uses its energy to convert carbon dioxide into glucose+oxygen 4 of 24 where does photosynthesis happen? In the leaves of all green plants 5 of 24 What does the limiting factor mean? The reason why photosynthesis does not take place. 6 of 24 what would be the limiting factor at night time? There is no sun to give the plant energy 7 of 24 what is the limiting factor in the winter? The temprature 8 of 24 What happens when there is not enough light? The rate of photosynthesis slows down 9 of 24 What does too little carbon dioxide do? The rate of photosynthesis slows down 10 of 24 What do digestive enzymes do? Break down big molecules into smaller ones 11 of 24 what are starch,proteins and fats? Big molecules 12 of 24 What are sugar,amino acids,glycerol and fatty acids Small molecules 13 of 24 What does amylase do? convert starch into sugars 14 of 24 What are the three places where amylase are made? The salivary glands,the pancreas and the small intestine 15 of 24 What does protease do? converts proteins into amino acids 16 of 24 what are the three main places where protease is made? the stomach,the pancreas and the small intestine 17 of 24 what does lipase do ? converts lipids into glycerol and fatty acids 18 of 24 what are the two places where lipase is made? the pancreas and the small intestine 19 of 24 What does bile do? neutralises the stomach acid and emulsifies fats 20 of 24 What are chromosomes? long molecules of DNA 21 of 24 where is DNA found? in the nucleus of animal and plant cells 22 of 24 What is a gene it is a section of DNA which contains the instructions to make specific protein 23 of 24 how do cells make proteins? by stringing amino acids together in a particular order. 24 of 24
