Detailed explanation-1: -Which analogy best describes the role enzymes play in cells? Like the fence around a yard, enzymes act as a barrier preventing entry to the cell.
Detailed explanation-2: -The specific action of an enzyme with a single substrate can be explained using a Lock and Key analogy first postulated in 1894 by Emil Fischer. In this analogy, the lock is the enzyme and the key is the substrate. Only the correctly sized key (substrate) fits into the key hole (active site) of the lock (enzyme).
Detailed explanation-3: -What Do Enzymes Do? Enzymes are protein catalysts that speed biochemical reactions by facilitating the molecular rearrangements that support cell function.
Detailed explanation-4: -Which statement best describes the role of an enzyme in this process? Because enzymes are proteins, they only react with other protein molecules, resulting in the production of glucose. The active site of the enzyme attached to the substrate of a food molecule produces carbon molecules, the building blocks of cells.
Detailed explanation-5: -Enzymes include detoxification, muscle building, and breaking down food particles during digestion. Enzymes actually accelerate the rate of a chemical reaction to support life. Enzymes are very helpful in performing important functions of our body.
