Question 91

Enzymes are proteins (A is wrong). Vitamins and minerals are not proteins (C is wrong). They do not provide energy (D is wrong). They are essential nutrients (E is wrong). Cofactors assist enzymes, and vitamins/minerals can act as cofactors.

A steak (A) and chicken wings (E) are high - in protein. Milk (B) and buttermilk (C) have some carbohydrates but also proteins and fats. Orange juice (D) is mainly simple carbohydrates (sugars) which can be quickly absorbed.

Answer:

B. cofactors.
