Question

Which of the following statements are TRUE about B vitamins?

a. Mostly work as coenzymes
b. Milled grains in the USA must be enriched with vitamin B1, B2, B3, and folate
c. People at risk for B-vitamin deficiency include alcoholics and elderly
d. A and B only
e. All of the above

Answer 1

The true statements about B vitamins include them working mostly as coenzymes, the requirement for milled grains in the US to be enriched with certain B vitamins, and alcoholics and elderly being risk groups for deficiency.

Step-by-step explanation:

The B vitamins primarily function as coenzymes in various metabolic processes essential for extracting energy from food. In the United States, milled grains are mandated to be enriched with vitamin B1, B2, B3, and folate to prevent deficiencies. Populations such as alcoholics and the elderly are particularly at risk for B-vitamin deficiencies due to poor dietary intake, absorption issues, or increased physiological needs.

B vitamins mostly work as coenzymes, which are molecules required for protein enzymes to function properly. Milled grains in the USA are enriched with vitamin B1, B2, B3, and folate to prevent deficiencies in these vitamins. People at risk for B-vitamin deficiency include alcoholics and the elderly.
