Complex carbohydrates (polysaccharides) are better for a person to eat than simple carbohydrates (monosaccharides) because:
They give the body essential amino acids
They give the body quick energy
They give the body nonessential amino acids
They give the body sustainable energy
The Correct Answer is D
A. They give the body essential amino acids: Carbohydrates do not provide amino acids; proteins are the primary source of amino acids.
B. They give the body quick energy: Simple carbohydrates (monosaccharides) provide quick energy as they are rapidly absorbed and metabolized.
C. They give the body nonessential amino acids: Carbohydrates do not contribute to amino acid supply; nonessential amino acids can be synthesized by the body.
D. They give the body sustainable energy: Complex carbohydrates, such as whole grains and fiber, provide long-lasting energy as they take longer to break down into glucose.

C. Component of hemoglobin: Hemoglobin is composed of iron and protein (globin chains), not lipids.
D. As a component of the cell membrane: Cell membranes are composed of a lipid bilayer (phospholipids and cholesterol), which helps maintain structural integrity and fluidity.
