• NaCl

• C6H12O6

• CO2

• H2O

Answer explanation

The chemical formula for the monosaccharide glucose is C6H12O6. It represents the correct choice among the answer options.

Name one example of a monosaccharide.

• glucose

• fructose

• starch

• sucrose

Answer explanation

Glucose is an example of a monosaccharide. It is a simple sugar that is essential for energy production in living organisms.

What are the two monosaccharides that make up the disaccharide sucrose?

• sucrose and fructose

• glucose and maltose

• glucose and fructose

• fructose and lactose

Answer explanation

Sucrose is made up of glucose and fructose, not sucrose and fructose, glucose and maltose, or fructose and lactose. The correct answer is glucose and fructose.

How are disaccharides different from monosaccharides?

• Disaccharides are composed of three monosaccharide units bonded together.

• Disaccharides are composed of two monosaccharide units bonded together.

• Disaccharides are composed of only one monosaccharide unit.

• Disaccharides are composed of non-carbohydrate molecules bonded together.

Answer explanation

Disaccharides are different from monosaccharides because they are composed of two monosaccharide units bonded together.

What is the function of polysaccharides in the body?

• Synthesis of neurotransmitters

• Transport of oxygen in the blood

• Regulation of body temperature

• Source of energy and structural support

Answer explanation

Polysaccharides function as a source of energy and provide structural support in the body.

Name one example of a polysaccharide.

• Starch

• Protein

• DNA

• Lipid

Answer explanation

Starch is an example of a polysaccharide. It is a complex carbohydrate made up of glucose molecules. Starch is commonly found in plants and serves as a storage form of energy.

What are simple carbohydrates and give an example?

• Fructose

• Protein

• Lipids

• Glucose

Answer explanation

Simple carbohydrates are sugars that are easily broken down by the body. An example of a simple carbohydrate is glucose, which is the correct choice.

How are complex carbohydrates different from simple carbohydrates?

• Complex carbohydrates are made up of only one sugar molecule.

• Complex carbohydrates are easier to digest than simple carbohydrates.

• Complex carbohydrates are made up of long chains of sugar molecules.

• Complex carbohydrates have fewer calories than simple carbohydrates.

Answer explanation

Complex carbohydrates are made up of long chains of sugar molecules, which distinguishes them from simple carbohydrates.

What are the benefits of consuming complex carbohydrates?

• Rapid energy spikes

• Increased risk of diabetes

• Sustained energy, weight management, and digestive health

• Digestive issues

Answer explanation

Consuming complex carbohydrates provides sustained energy, aids in weight management, and promotes digestive health.

Name one example of a complex carbohydrate.

• Whole grains

• Candy

• Soda

• White bread

Answer explanation

Whole grains are an example of a complex carbohydrate. They contain fiber and take longer to digest, providing sustained energy.
