1.

What are the basic building blocks of carbohydrates?

a)

Amino acids

b)

Monosaccharides

c)

Disaccharides

d)

Polysaccharides

2.

Define disaccharides and provide two examples.

a)

Disaccharides are proteins found in meat.

b)

Examples of disaccharides include starch and cellulose.

c)

Glucose and fructose are monosaccharides.

d)

Examples of disaccharides include sucrose (table sugar) and lactose (milk sugar).

3.

What is the primary function of polysaccharides in living organisms?

a)

DNA replication

b)

Protein synthesis

c)

Cellular respiration

d)

Energy storage and structural support.

4.

Outline the main steps of the glycolysis pathway.

a)

The main steps of glycolysis include phosphorylation, isomerization, cleavage, oxidation, and ATP generation.

b)

Fermentation, condensation, hydrolysis, and ATP consumption.

c)

Transamination, methylation, oxidation, and NADH production.

d)

Decarboxylation, reduction, polymerization, and glucose synthesis.

5.

What is the role of glycogen in energy storage?

a)

Glycogen is a type of protein that provides structural support.

b)

Glycogen acts as a stored form of glucose for energy, readily converted to glucose when needed.

c)

Glycogen is a hormone that regulates blood sugar levels.

d)

Glycogen is primarily used for fat storage in the body.

6.

Describe the process of carbohydrate digestion in the human body.

a)

Monosaccharides are absorbed directly in the mouth.

b)

Carbohydrate digestion occurs only in the stomach.

c)

Carbohydrates are not digested and are excreted whole.

d)

Carbohydrate digestion involves enzymatic breakdown starting in the mouth, continuing in the small intestine, and absorption of monosaccharides.

7.

How do carbohydrates impact overall health?

a)

Carbohydrates are the main source of protein in the diet.

b)

Carbohydrates have no effect on energy levels.

c)

Carbohydrates provide energy, support digestive health, and can impact weight and chronic disease risk.

d)

Carbohydrates are solely responsible for weight gain.

8.

What is the significance of insulin in carbohydrate metabolism?

a)

Insulin facilitates glucose uptake and storage, regulating blood sugar levels.

b)

Insulin has no effect on carbohydrate metabolism.

c)

Insulin is primarily responsible for fat metabolism and storage.

d)

Insulin decreases glucose uptake and increases blood sugar levels.

9.

Explain how nursing practice can incorporate knowledge of carbohydrates.

a)

Nursing practice can ignore carbohydrate intake entirely.

b)

Nurses should only focus on protein and fats in diet planning.

c)

Carbohydrates are not relevant to blood sugar levels.

d)

Nursing practice can incorporate knowledge of carbohydrates by assessing dietary intake, educating on blood sugar management, and collaborating with dietitians for meal planning.

10.

What are the potential health risks associated with excessive carbohydrate intake?

a)

Weight gain, insulin resistance, elevated triglycerides, nutrient deficiencies.

b)

Increased energy levels

c)

Improved digestion

d)

Lower blood pressure
