Glucose Metabolism | MCQs

Explanation

Diabetes is a condition where blood glucose levels become too high or too low due to insulin problems.

It includes Type 1, Type 2, and gestational diabetes, affecting how the body uses sugar for energy.

Explanation

In the normal resting state of humans, most of the blood glucose burned as "fuel" is consumed by the brain.

The brain relies primarily on glucose for energy and consumes a significant portion of the body's glucose, even at rest.

Explanation

nsulin is produced by the pancreas, which is an organ located behind the stomach.

The pancreas contains clusters of cells called the Islets of Langerhans, specifically the beta cells within these islets, which are responsible for producing insulin.

Insulin plays a crucial role in regulating blood sugar levels by facilitating the uptake of glucose into cells for energy production or storage.

When blood sugar levels rise after a meal, the pancreas releases insulin to help lower blood sugar levels by promoting the uptake of glucose into cells.

Explanation

Cellulose is the most abundant carbohydrate in plants and a major component of the plant cell wall.

It provides structural support.

It is made of long chains of glucose molecules.

Explanation

Glycolysis produces a net gain of 2 ATP molecules (4 produced – 2 used) per glucose molecule.

It also generates 2 NADH molecules, which can be used in oxidative phosphorylation for further ATP production.

Explanation

• 2 ATP molecules are consumed in the initial steps
• 4 ATP molecules are produced in the later steps

Explanation

Insulin converts glucose into lipids.

It facilitates the uptake of glucose by cells.

This promoting its storage as glycogen and conversion into fatty acids for energy storage in the form of lipids.
