Carbohydrates contribute 4 calories per gram, as do sugars since they are carbohydrates, and water contributes 0 calories per gram.

3. Which of the following contributes the fewest calories per gram?

Answer: Fiber

Fiber contributes minimal calories per gram because the body does not digest and absorb fiber, although a small amount of soluble fiber can provide around 2 calories per gram, according to the FDA. Carbohydrates and proteins both contribute 4 calories per gram, and lipids contribute 9 calories per gram.

4. The two types of carbohydrates are organic and inorganic.

Answer: False

Carbohydrates can either be complex or simple.

5. Which disaccharide is composed of glucose and fructose?

Answer: Sucrose

Lactose is composed of galactose and glucose, maltose is composed of glucose and glucose, as is trehalose(lactose and trehalose are isomers).

6. What is the common name for sucrose?

Answer: Sugar

Sucrose, or sugar, is a disaccharide composed of glucose and fructose.

7. What enzyme is used to break down starches?

Amyl- means starch in Latin, and -ase means enzyme in Latin.

8. In an iodine-solution test for starch, what color will a sample turn if starch is present?

Answer: Blue/black

If the test is negative, the sample is golden-brown.

9. An unsaturated fat has double bonds.

Answer: True

A polyunsaturated fat has multiple double bonds, and a monounsaturated fat has a single double bond. A saturated fat has the maximum number of hydrogen atoms it can hold, and has no double or triple bonds.

10. Of the following sugars, which produces carbon dioxide gas the fastest when it reacts with yeast?
