6. Using graph C:a. Explain what happens when hypothermia sets in(when enzymes get too cold!)Reaction Rate vs Substrate ConcentrationISubstrate Concentuationb. Does the same thing happen when enzymes get toohot? Why or why not?7. Explain why graph D levels off. Use enzyme and substratein your explanation. Then tell how you could prevent graphD from leveling off.Rate of Reaction - Enzyme Concentration8.Why doesn't it matter if enzymes keep gettingadded to graph E? What would it take to increase the rate of enzyme activity?Then answer the following questions:1. Transfer of Energy and Matter: Is an enzyme used up in a chemical reaction?Explain.2. Transfer of Energy and Matter:How would your diagram be different if the enzyme activity was anabolicinstead of catabolic? (E.g., an enzyme to build muscle proteins).a.Rate of Reaction

Enzymes are catalysts and increase the speed of a chemical reaction without themselves undergoing any permanent chemical change. 2. Catalysis is defined as the acceleration of a chemical reaction 3. if the amount of the enzyme is kept constant and the substrate concentration is then gradually increased, the reaction velocity will decrease. 4. In the Induced-fit Model, if a dissimilar substance which does not fit the site is present, the enzyme rejects it 5. The Michaelis constant Vo is defined as the substrate concentration at 1/2 the maximum velocity. 6.
