Whether it’s the three factors that I mentioned in the AP Biology Lab on enzymes, that often is in the essay portion. Or those helper molecules called co-enzymes or cofactors that help enzymes do their job. When you’re studying enzymes, a really good model to use to help you figure it out, are a pair of scissors. For example, if you’re trying to tear a piece of paper in half, by grabbing.

Enzymes are protein substances. They contain acidic carboxylic groups (COOH), and basic amino groups (NH 2). Enzymes are affected by the changing of pH value. Each enzyme has a pH value at which it works with maximum efficiency called the optimal pH. If the pH is lower or higher than the optimal pH, the enzyme activity decreases until it stops.

Enzyme catalysis is when enzymes which are globular proteins with a three-dimensional shape that fit around some molecules to facilitate chemical reactions (Raven et al 2008). Support proteins fibres play a structural role, these fibres include keratin in hair fibrin in blood clots and collagen which forms the matrix of skin, ligaments, tendons, and bones, and is the most abundant protein in a.

AP Biology Practice Free Response Question: Biochemistry On the AP Biology Exam this May, you will have 90 minutes to complete the free-response section that represents 40% of your score. There are four questions in the free-response section. Therefore, you will have approximately 20 minutes to complete each question. You will also have 10 minutes at the beginning to brainstorm your answers.

Enzymes work within a small pH range, therefore pH levels tend to have a great impact on the enzyme-substrate activity (Nelson Biology 12). Any pH level above or below 7 started to denature the enzyme, slowing down the rate of reaction. Denaturing enzymes meant that the shape of the overall enzyme had changed. This meant that at the pH levels of 2, 4, 9 or 12 the shape of the active site for.
