Control of metabolic processes

Which type of catalysis involves the formation of a covalent bond between the enzyme and the substrate?

Covalent catalysis

What is the significance of Km in the Michaelis-Menten equation?

It is the substrate concentration at which the reaction rate is half of Vmax.

Which type of inhibition involves a molecule that competes with the substrate for binding to the active site of the enzyme?

Reversible competitive inhibition

What is a possible consequence of deficiencies in enzyme catalytic activity?

Genetic defects

Allosteric regulation

Where are enzymes synthesized?

Ribosomes attached to the rough endoplasmic reticulum

What is the purpose of compartmentalization of enzymes within a cell?

To isolate reaction substrates or products
