Fatty acids, amino acids and simple sugars 3 of 11 What is the lock and key theory? The lock and key theory is the theory that only specific enzymes can fit into/work on certain substrates. 4 of 11 What are protease? Protease are enzymes that act on proteins. 5 of 11 What are the 5 main types of protein? Defence and Imuno, Hormones, Enzymes, Structural & Carrier and Storage molocules 6 of 11 What are proteins broken down into and why? Proteins are broken down into amino acids, this is because we need the amino acids for growth, maintenance and to repair tissue. 7 of 11 What is a substrate? The substrate is the food involved in the reaction 8 of 11 What is a 'enzyme substrate complex'? A enzyme substrate complex is the faze when the enzyme and substrate join. 9 of 11 What is osmosis? Osmosis is the movement of water through a semi-permeable membrane from an area of low concentration to an area of high concentration 10 of 11 Why are enzymes sometimes called 'biological catalysts'? Because biological catalysts are things that speed up a reaction and enzymes do just that. 11 of 11
