- 1What are enzymes made out of?Enzymes are proteins which are made from amino acids.
- 2How is a protein made?When amino acids come to a ribosome, the ribosomes join the amino acids together. This is called a protein.
- 3How are different proteins made?Amino acids join together into a chain. They are joined into a different order to make different proteins.
- 4What are the characteristics of a protein?Proteins fold into specific shapes and they can attach to other molecules depending on their shapes.
- 5Why are enzymes called proteins?Enzymes make reactions go faster so we call them proteins.
- 6What is the bit which enzymes attach toEnzymes attach to other molecules which are called the substrate.
- 7What does the enzyme do?The enzyme breaks down the substrate and releases the product.
- 8What happens to the enzyme at high temperatures?At high tempretaures the shape of the enxzyme changes so the substrate can no longer fit to the enzyme
- 9What do we say if the enzyme stops working?The enzyme stops working. We say the enzyme has been denatured.
- 10Why can't we use say the enzyme has been killed.Remember, the enzyme is not a living organism the enzyme is a protein molecule and you cant kill a molecule. When we heat an enzyme we are changing its shape we can say it has been destroyed or DENATURED.
- 11What happens to the enzyme at different at PHs?Every enzyme works best at a specific PH. At different PHs the enzyme stop working as the shape is changed
