Question

used up by the chemical reaction. once it has participated in a chemical reaction, the enzyme can be used again.
figure 16 illustrates how enzymes function in chemical reactions, facilitating cellular processes. enzymes have unique structures that essentially bring reactants facilitating. the reactants that to an enzyme are called a active site. the specific location where a substrate binds an enzyme is called the site.
the active and the have complementary shapes. this enables them to in a precise manner, similar to the way pieces fit together. the structure of an enzyme is directly related to its function. only substrates with the size and shape as the active site will to the.
once a substrate to an site, the active site changes shape and the -substrate complex. the enzyme- helps chemical bonds in the to be broken and bonds to form. during this process the react to form products. the enzyme then releases the.
since only certain substrates bind to specific enzymes, it might not surprise you that most enzymes are named for the they act upon. for example, is an important enzyme found in. digestion of food begins in the mouth when speeds the breakdown of the substrate, one of the components of. other examples include a group of digestive enzymes called and the enzyme. protease breaks down and lipase breaks down fats ( ) in food.

Explanation:

Enzymes are biological catalysts. Reactants that bind to an enzyme are substrates and they bind at the active - site. The enzyme - substrate complex formation is like a lock - and - key fit. Enzymes help break and form chemical bonds in substrates to create products. Many enzymes are named for their substrates, such as amylase in saliva which breaks down starch. Protease breaks down proteins and lipase breaks down lipids.
