Examples of biological enzymes

Answer 1

Examples:

• Catalase. It catalyzes the decomposition of hydrogen peroxide into water and oxygen.

  2H2O2 -> 2H2O + O2

  One molecule of catalase can break 40 million molecules of hydrogen peroxide each second.

• Carbonic anhydrase. It is found in red blood cells where it catalyzes the reaction

  CO2 + H2O ↔ H+ + HCO3−

  It enables red blood cells to transport carbon dioxide from the tissues to the lungs. [Discussion]

  One molecule of carbonic anhydrase can process one million molecules of CO2 each second.

• Acetylcholinesterase. It catalyzes the breakdown of the neurotransmitter acetylcholine at several types of synapses as well as at the neuromuscular junction - the specialized synapse that triggers the contraction of skeletal muscle.

  One molecule of acetylcholinesterase breaks down 25,000 molecules of acetylcholine each second. This speed makes possible the rapid "resetting" of the synapse for transmission of another nerve impulse.

Answer 2

Examples of biological enzymes include amylase, which helps break down carbohydrates into sugars, and protease, which catalyzes the breakdown of proteins into amino acids. Another example is catalase, which converts hydrogen peroxide into water and oxygen.

Answer 3

Lactase, Maltase, and Sucrase are all biological enzymes. Enzymes are used to start and accelerate the chemical reactions of the body.

Answer 4

Phospholipase
