Glucose Regulation
(154).jpg "Glucose Regulation - Quiz")
Our bodies require energy to do everything, from pumping blood into capillaries to walking. This energy originates from glucose in the food we eat. Too much or inadequate glucose is dangerous hence, the glucose regulation quiz below.
- 1.
Insulin is released by what type of cells in the pancreas?
- A.
Beta cells
- B.
Alpha cells
- C.
Beta and alpha cells
- D.
Option 4
Correct Answer
A. Beta cellsExplanation
Insulin is released by beta cells in the pancreas. These cells are responsible for producing and secreting insulin, a hormone that helps regulate blood sugar levels. Insulin plays a crucial role in facilitating the uptake of glucose by cells, thereby reducing blood sugar levels. Alpha cells, on the other hand, produce and release glucagon, a hormone that raises blood sugar levels. Therefore, the correct answer is beta cells.Rate this question:

What is the key role of the kidney in glucose regulation?
- A.
Production of insulin
- B.
Reabsorption of glucagon
- C.
Production of glucose
- D.
Reabsorption of glucose
Correct Answer
D. Reabsorption of glucoseExplanation
The key role of the kidney in glucose regulation is the reabsorption of glucose. The kidneys filter the blood and remove excess glucose, which is then reabsorbed back into the bloodstream to maintain normal blood glucose levels. This process helps prevent the loss of valuable glucose through urine and ensures that glucose is available for energy production in the body.Rate this question:

Which organs are responsible for the uptake of glucose?
- A.
Liver
- B.
Muscle
- C.
Kidney
- D.
Heart
Correct Answer
B. MuscleExplanation
Muscle is responsible for the uptake of glucose. When glucose is present in the bloodstream, muscle cells have insulin receptors that allow them to take in glucose and use it as a source of energy. This is important for muscle contraction and overall energy metabolism. The liver also plays a role in glucose uptake and storage, but in this question, muscle is the primary organ responsible for glucose uptake. The kidney and heart do not have a major role in glucose uptake.Rate this question:

Insulin promotes following processes in the liver?
- A.
Glycogenesis
- B.
Glycogenolysis
- C.
Gluconeogenesis
- D.
Gycolysis
Correct Answer
A. GlycogenesisExplanation
Insulin promotes glycogenesis in the liver. Glycogenesis is the process of converting glucose into glycogen, which is stored in the liver for later use as an energy source. Insulin stimulates the liver cells to take up glucose from the bloodstream and convert it into glycogen. This helps to regulate blood sugar levels by removing excess glucose from the bloodstream and storing it as glycogen.Rate this question:

Fatty acids in the liver are transformed to glucose through gluconeogenesis?
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
Gluconeogenesis is a metabolic pathway that allows the liver to produce glucose from non-carbohydrate sources, such as fatty acids. This process is important for maintaining blood sugar levels during fasting or periods of low carbohydrate intake. Therefore, the statement that fatty acids in the liver are transformed to glucose through gluconeogenesis is true.Rate this question:
