Enzymes are catalysts. They are usually proteins, though some RNA molecules act as enzymes too. Enzymes lower the activation energy of a reaction - that is the required amount of energy needed for a reaction to occur. They do this by binding to a substrate and holding it in a way that allows the reaction to happen more efficiently. Saturable versus non-saturable kinetics. The rate of a biologic process can be described by the Michaelis-Menten equation: (1) Where dC is a change in concentration, dt is a change in time, V max is the maximal biologic rate, K m is an affinity constant defined as the concentration at which rate is half of Vmax, and C is concentration. If C is ...Explore the vital role of enzymes in speeding up biochemical reactions in the body, as you learn about the different catalytic strategies enzymes use, including acid/base catalysis, covalent catalysis, electrostatic catalysis, and proximity and orientation effects.

Oct 22, 2018 · Enzymes permit a vast number of reactions to take place in the body under conditions of homeostasis, or overall biochemical balance.For example, many enzymes function best at a pH (acidity) level close to the pH the body normally maintains, which is in the range of 7 (that is, neither alkaline nor acidic). Some enzymes even distinguish between D- and L-stereoisomers, binding one stereoisomer but not the other. Urease, for example, is an enzyme that catalyzes the hydrolysis of a single substrate—urea—but not the closely related compounds methyl urea, thiourea, or biuret. The enzyme carboxypeptidase, on the other hand, is far less specific.Enzymes are proteins that act as biological catalysts by accelerating chemical reactions.
