How do enzymes affect a chemical reaction, making it easier to occur?
Annette [7]

Enzymes affect a chemical reaction, making it easier to occur by reducing the activation energy; <u>option B</u>

<h3>What are enzymes?</h3>

Enzymes are biological molecules that alter the rate of chemical reactions occurring in the body.

Enzymes usually speed up the rate of reactions by making the reactions less energy-demanding, that is by lowering the activation energy of the biochemical reaction.

Enzymes are usually proteins, hence are affected by the conditions of temperature and pH.

Enzymes are also very specific in the substrate they act upon.

Extrapyramidal effect of metoclopramide.
SIZIF [17.4K]

Answer:

Metoclopramide is a drug widely used for its antiemetic effect (that is, used for the symptomatic treatment of nausea and vomiting). Its adverse reactions are varied, affecting even the central nervous system, causing extrapyramidal syndromes.

Explanation:

Due to the antidopaminergic action of metoclopramide. Signs and symptoms can range from spasms of the muscles of the face, neck or tongue, motor agitation and tremor, acatisia (feeling restless and in need of constant movement) and acute dystonic reactions. Extrapyramidal syndrome is transient and disappears after eliminating or decreasing the dose of metoclopramide.

Metoclopramide is a drug that can be administered intravenously. Its administration can be in bolus or by a continuous infusion. Is there any method of choice to prevent or reduce the occurrence of pyramidal syndromes?

A recent systematic review concluded that, compared with bolus administration, continuous intravenous infusion of metoclopramide reduced the occurrence of extrapyramidal side effects.

With this gesture we can perform quality care and try to avoid side effects to our patients.

Dennis_Churaev [7]

Answer:

The cells inside our bodies are “specialized.” This means that each type of cell performs a unique and special function. For this reason, each of the 200 different types of cells in the body has a different structure, size, shape, and function, and contains different organelles.

We are multicellular organisms, different types of cells are required to do different function.

Explanation:

Actually cells in our body won't reproduce, LOL.
