1. Enzymes function more efficiently at the temperature of a typical cell, which is 37°Celsius. Increases or decreases in temperature can significantly lower the reaction rate. What does this suggest about the importance of temperature-regulating mechanisms in organisms? Question 1 options:
A. Increases in temperature might alter the rate of activity and shape of the organisms atomically. This can affect them negatively since with such drastic changes, they will no longer be able to function properly.
B. Temperature regulation in organisms is the essential maintenance of metabolic reactions. Altering the temperature would affect the rate of enzyme activity which, in turn, might have major consequences on the ability of the organisms to function.
C. Organisms need to be able to maintain a temperature in order to create food and stay alive. They need more reactants to maintain this temperature however because it uses a lot of energy.
D. It keeps enzymes healthy so they don't lose their function to help a reaction happen.
2.Why is it that the maximum initial reaction rate cannot be reached at low substrate concentrations? Question 2 options:
A. There aren't enough substrates available to react.
B. Because the more of the substrate, the higher the reaction rate is going to be until it reaches its maximum.
C. Because at low substrate not all the active sites on the enzyme molecules will be occupied with substrate.
D. Because collisions between the substrate and enzyme do not occur as often to allow for the conversion of the substrate.
3. What was the source(s) of catalase enzyme in the reaction? Question options:
A. Just the liver.
B The foods (potato and liver) are both sources of catalase.
C. O2
D. H2O2
