Which of the following is false regarding protein kinase A (PKA)?

Which of the following is false about cyclin-dependent kinases (Cdks)?

In the last step of glycolysis, what is the name of the enzyme that converts phosphoenolpyruvate into pyruvate?

Which of the following enzymes catalyzes a reaction that is the functional opposite of the reaction catalyzed by kinases?

Enzymes can be regulated in a multitude of ways. One such way is by covalent modification, in which functional groups are attached to or removed from the enzyme. One such functional group that can be added to an enzyme is a phosphate group. Depending on the enzyme, addition of a phosphate group may increase or decrease that enzyme's activity. Which of the following is the general name of an enzyme that functions to add phosphate groups to its substrate?

Kinases catalyze the phosphorylation of other proteins/substrates, which may trigger their activation. Phosphorylation involves the addition of a phosphate group to the target molecule. Amino acids with a(n) __________ R-group are typically the substrates for phosphorylation.
