Understanding how enzymes work
1) Excluding enzymes, for example, that work in the stomach's low pH, describe the working conditions for most enzymes in the human body.
2) Describe the effect of enzymes on the rate of reactions that they catalyze.
3) Define the transition state in a chemical reaction and how an enzyme functions during the transition state.
8). Which statement best describes
1 point
the enzyme represented in the
graphs?
O 10 20 30 40 50 60
O 2 4 6

Temperature ("C)
PH
(1) This enzyme works best at a
temperature of 50°C and a pH of 12.
(2) Temperature and pH have no effect on
the action of this enzyme.
(3) This enzyme works best at a
temperature above 50°C and a pH above 12.
(4) This enzyme works best at a
temperature of 35°C and a pH of 8.

Estimate the concentration of an enzyme in a living cell. Assume that fresh tissue is 80% water and all of it is intracellular, the total soluble protein in a cell represents 15% of the weight, all the soluble proteins are enzymes, the average weight of a protein is 150000 and about 1000 different enzymes are present.
