Biguanides are :
-
Antihypertensive drugs
-
Antidiabetic drugs
-
Antiemetic drugs
-
Antidiarcal drugs
Correct Answer
A. Antidiabetic drugsExplanation
Biguanides are a class of drugs that are commonly used to treat type 2 diabetes. They work by reducing the amount of glucose produced by the liver and improving the body's response to insulin. Examples of biguanides include metformin, which is one of the most commonly prescribed medications for diabetes. These drugs are not used for treating hypertension, nausea, or diarrhea, so they are not antihypertensive, antiemetic, or antidiarrheal drugs. Therefore, the correct answer is antidiabetic drugs.Rate this question:

In the muscles, Insulin inhibits anabolism, and induces protein catabolism, and decrease amino acids transport.
Correct Answer
A. In the muscles, Insulin inhibits anabolism, and induces protein catabolism, and decrease amino acids transport.Explanation
Insulin is a small protein comprising 51 amino acid residues, synthesized in the B-cells of the Langerhans via its precursor, proinsulin. One molecule of proinsulin is cleaved by enzymes to give one molecule of insulin and one molecule of -peptide. However, in the muscles, insulin does not inhibit anabolism or induce protein catabolism. Instead, it promotes anabolism by stimulating glucose uptake and glycogen synthesis, and it also enhances amino acid transport, which is essential for protein synthesis.Rate this question:

Which of the following is an important effect of insulin?
-
Increased conversion of amino acids into glucose
-
Increased gluconeogenesis
-
Increased glucose transport into cells
-
Inhibition of lipoprotein lipase
-
Stimulation of glycogenolysis
Correct Answer
A. Increased glucose transport into cellsExplanation
Insulin plays a crucial role in regulating glucose levels in the body. One of its important effects is the increased transport of glucose into cells. Insulin binds to insulin receptors on the cell surface, triggering a cascade of events that result in the insertion of glucose transporters (GLUT4) into the cell membrane. This allows glucose to enter the cells and be utilized for energy production or stored as glycogen. Increased glucose transport into cells helps to lower blood glucose levels and maintain cellular energy balance.Rate this question:

Beef Insulin differs from human insulin by
-
3 amino acids
-
2 amino acids
-
1 amino acids
-
4 amino acids
Correct Answer
A. 3 amino acidsExplanation
Beef insulin differs from human insulin by 3 amino acids. Amino acids are the building blocks of proteins, and insulin is a protein hormone. These three amino acids may cause slight differences in the structure and function of beef insulin compared to human insulin. These differences can affect the way beef insulin interacts with insulin receptors in the body, potentially leading to variations in its effectiveness or side effects when used in medical treatments.Rate this question:

Which of the following is true in regard to Insulin?
-
It needs opening of K+ channels to be secreted from B-cells
-
It needs closure of K+ channels to be secreted from B-cells.
-
It needs closure of Ca+2 channels to be secreted from B-cells
-
The ATP/ADP ratio is in favour of ADP
Correct Answer
A. It needs closure of K+ channels to be secreted from B-cells.Explanation
Insulin is secreted from B-cells in response to high blood glucose levels. In order for insulin to be secreted, the K+ channels on the B-cells need to close. This closure of K+ channels leads to depolarization of the B-cell membrane, which triggers the opening of Ca+2 channels. The influx of Ca+2 ions then stimulates the release of insulin from the B-cells. Therefore, the statement "It needs closure of K+ channels to be secreted from B-cells" is true.Rate this question:

Regarding Insulin, the following are true, except:
-
It causes gluconeogenesis.
-
It is a peptide.
-
It may cause hypoglycaemia
-
Insulin lispro in an ultra short acting preparation
Correct Answer
A. It causes gluconeogenesis.Explanation
Insulin is a peptide hormone that is produced by the pancreas and plays a crucial role in regulating blood sugar levels. It works by promoting the uptake and storage of glucose in cells, thereby lowering blood glucose levels. However, it does not cause gluconeogenesis, which is the production of glucose from non-carbohydrate sources. Instead, insulin inhibits gluconeogenesis to prevent excessive glucose production. Therefore, the statement "It causes gluconeogenesis" is incorrect.Rate this question:

Which of the following is not true concerning Metformin?
-
It works by reducing hepatic glucose output
-
It works by enhancing insulin sensitivity in peripheral tissues
-
It reduces the plasma triglycerides level.
-
It works by enhancing insulin release from the B-cells of pancreas.
Correct Answer
A. It works by enhancing insulin release from the B-cells of pancreas.Explanation
Metformin is an oral medication commonly used to treat type 2 diabetes. It works by reducing hepatic glucose output, meaning it decreases the amount of glucose produced by the liver. Additionally, it enhances insulin sensitivity in peripheral tissues, which helps the body use insulin more effectively. Metformin also has the benefit of reducing plasma triglyceride levels. However, it does not directly enhance insulin release from the B-cells of the pancreas. Instead, it primarily targets the liver and peripheral tissues to improve glucose control.Rate this question:

Which of the following about a-glucosidase inhibitors is not true?
-
They have a direct effect on insulin release.
-
They slow the digestion of complex carbohydrates in GIT.
-
Can be used with oral hypoglycacmic drugs
-
Their common adverse effects are flatulence and bloating.
-
Miglitol is one example of these drugs.
Correct Answer
A. They have a direct effect on insulin release.Explanation
a-glucosidase inhibitors do not have a direct effect on insulin release. Instead, they slow the digestion of complex carbohydrates in the gastrointestinal tract (GIT). This leads to a slower release of glucose into the bloodstream, helping to control blood sugar levels. They can be used in combination with oral hypoglycemic drugs to further manage diabetes. Common adverse effects of a-glucosidase inhibitors include flatulence and bloating. One example of these drugs is miglitol.Rate this question:
