And on Monday afternoon, Jamaican sprinter Bolt spent time reviewing the pictures and retweeting them to his more than 3.5million followers. Lightning fast: Usain Bolt strikes a familiar pose after winning the Olympic 100m gold medal. He also added tongue-in-cheek words of encouragement to his young fans on the social network, describing their efforts as epic, sweet, perfect and saying one was a natural.
Enzymes are special types of proteins. Like all proteins, enzymes are made from strings of amino acids. The function of the enzyme is determined by the sequence of amino acids, types of amino acids, and the shape of the string.
Enzymes are biological molecules that catalyse (speed up) chemical reactions. Enzymes are specificâthey will only work on particular molecules. For example, the enzyme sucrase will only bind with and break bonds in sucrose, not any other type of sugar.nother characteristic of enzymes is that they can be re-used over and over again. A single enzyme will typically catalyse around 10,000 chemical reactions per second. This means that only a tiny amount of enzyme is needed to have a huge effect on a reaction.
