Which of the following statements is FALSE?

Question

a. Enzymes speed up the attainment of a reaction equilibrium.

b. Enzymes make reactions 10^3 to 10^20 times faster.

c. Enzymes are chemically unchanged during the actual catalytic process.

d. Enzymes are proteins. e. Enzymes lower the amount of energy needed for a reaction.

f. All of the above

g. None of the above

Answer 1

Ribozymes are not proteins.

Enzymes lower the peak of the potential hill--activation energy.

Rate is proportional to exp{-Ea / RT]

Hence--enzymes speed reations--bio enzymes do so to the degree/scale indicated in (b)--enzymes are preserved at fin like other catalysts--and "amt of energy needed" i.e activation energy is lowered as stated...
