Enzyme - AnsGlobular proteins that act as catalysts of chemical reactions Active Site - AnsRegion on the surface of an enzyme to which substrates bind and which catalyzes a chemical reaction involving substrates Enzyme-substrate specificity - AnsThe active sites of enzymes are specific to their substrates because it has a very specific shape, which means enzymes can catalyze only certain reactions as only a small number of substrates fit in the active site Effect of temperature on enzym...
