1. Provitamins are supplied in the diet.
2. Vitamins are similar in the nutritional roles they play.
3. Disease results when vitamins are not present in adequate amounts.
4. The body synthesizes necessary vitamins.
5. Vitamins can be taken as often as necessary.
Correct Answer: 1, 3
Rationale 1: Human cells cannot synthesize vitamins with the exception of vitamin D. Provitamins must be supplied in the diet. If the vitamin is not present in adequate amounts, the body's metabolism will be disrupted, and disease will result. Vitamins serve diverse and important roles in human physiology-e.g., as co-enzymes for metabolic pathways, precursors for retinal, and assisting with blood clotting.
Rationale 2: Vitamins are similar in the nutritional roles they play is incorrect because vitamins serve diverse and important roles in human physiology—e.g., as co-enzymes for metabolic pathways, precursors for retinal, and assisting with blood clotting.

Rationale 4: The body synthesizes necessary vitamins is incorrect because human cells cannot synthesize vitamins with the exception of vitamin D.
Rationale 5: Vitamins can be taken as often as necessary is incorrect because vitamins can cause adverse reactions. They should only be taken as directed.
