Question

1 — vitamins b₁ and b₂
learning objective: indicate the type, source, and role of vitamins b₁ and b₂.

b vitamins are considered to be ________.

a.) water soluble
b.) unabsorbable
c.) insoluble
d.) fat soluble

Explanation:

Vitamins are classified into water - soluble and fat - soluble. B vitamins (including \(B_1\) and \(B_2\)) and vitamin C are water - soluble vitamins. Fat - soluble vitamins include A, D, E, K. Option b is incorrect as B vitamins are absorbable. Option c is wrong as they are soluble. Option d is incorrect as they are not fat - soluble. So B vitamins are water - soluble.

Answer:

a.) water soluble
