- Based on the graphical information in Problem 21-41 about enzymes A and B a. What is the optimum pH for enzyme B? b. What is the optimum temperature for enzyme A? c. Which enzyme has the greater activity at a pH of 7.2? d. Which enzyme has the greater activity at a temperature of 37.2C?arrow_forwardThe human body has an average pH of about 7 and a temperature of about 37C. Use graphs to illustrate enzyme activity in the human body as a function of the following: a. Substrate concentration b. Enzyme concentration c. pH include pH optimum value d. Temperature include temperature optimum valuearrow_forwardDescribe the importance of zymogens in the body. Give an example of an enzyme that has a zymogen.arrow_forward
- Based on the graphical information in Problem 21-41 about enzymes A and B indicate whether the enzyme activity of enzyme B increases or decreases when the following changes in reaction conditions are made. a. pH decreases from 7.6 to 7.2 b. pH increases from 7.2 to 7.4 c. temperature decreases from 37.8C to 37.6C d. temperature increases from 38.2C to 38.4Carrow_forwardIn the multienzyme sequence shown below, molecules of D are able to fit to the enzyme E1 and prevent the conversion of A to B.
