Question

2) To which of the major classes of enzymes does the enzyme that catalyzes each of the following reactions belong?.

a) A cis double bond is converted to a trans double bond.

b) An alcohol is dehydrated to form a compound with a double bond.

c) An amino group is transferred from one substrate to another.

d) An ester linkage is hydrolyzed.

5) Temperature affects enzymatic reactions rates in two ways. An increase in temperature can accelerate the rate of a reaction or it can stop the reaction. Explain each of these effects.

6) In an enzyme-catalyzed reaction, all of the enzyme active sites are saturated by substrate molecules at a certain substrate concentration. What happens to the rate of the reaction when this substrate concentration is doubled?
