Question

Acetylcholinesterase (AChE) is a protein that catalyzes the conversion of acetylcholine to acetate and choline. When the concentration of AChE in an aqueous solution is held constant, the rate of the reaction catalyzed by AChE increases with increasing concentrations of substrate. At low concentrations of acetylcholine, a small increase in the substrate concentration results in a large increase in the reaction rate. At high concentrations of acetylcholine, however, a large increase in the substrate concentration results in only a small increase in the reaction rate. Which of the following statements correctly explains the observed effect of the acetylcholine concentration on the rate of the enzyme-catalyzed reaction?

Answer 1

The following statements correctly explains the observed effect of the acetylcholine concentration on the rate of the enzyme-catalyzed reaction: The active site of AChE is specific for acetylcholine, and only one substrate molecule can occupy the active site at a time.

Explanation:

Enzymes are macromolecular biological catalysts that accelerate chemical reactions.

Some of these enzymes include:

• Erepsin that converts peptones and polypeptides into amino acids.
• Maltase that converts maltose into glucose.
• Lactase that This is a significant enzyme that converts lactose into glucose and galactose.
• Sucrase that converts sucrose into glucose and fructose.

Answer 2

The correct statement is that the concentration of acetylcholine will be inhibited by enzymes and can cause several diseases as follows:

• Alzheimer's disease-related to damage to brain cells,
• memory loss,
• and thinking ability.

How to reduce the symptoms of these diseases is to use drugs that contain cholinesterase inhibitors.

Further Explanation

Acetylcholine is a neurotransmitter that plays an important role in the functioning of the autonomic nervous system. Acetylcholine is one of the most commonly recognized neurotransmitters or nerve stimulating chemicals. These neurotransmitter compounds can be found in the nervous system.

There are several side effects of the acetylcholine drug, which are as follows:

• Can cause a lot of sweat
• Excessive salivation
• Stomach ache
• Headache
• Blood vessel dilation
• Nausea and vomiting
• Diarrhea is a sign of an increase in parasympathetic tone.
