Concept explainers
(a)
Interpretation: Whether Vitamin A would be likely to be toxic when consumed in excess has to be predicted.
Concept introduction: When fat-soluble vitamins are consumed in excess, they can be toxic because they are stored in fat tissues. However, water-soluble vitamins are eliminated from the body through urine. Therefore, they are not likely to reach toxic levels.
(b)
Interpretation: Whether Vitamin

(c)
Interpretation: Whether Vitamin E would be likely to be toxic when consumed in excess has to be predicted.
Concept introduction: When fat-soluble vitamins are consumed in excess, they can be toxic because they are stored in fat tissues. However, water-soluble vitamins are eliminated from the body through urine. Therefore, they are not likely to reach toxic levels.
(d)
