Ascorbic acid is a vitamin used by?
- A. Humans, but not for most other animals
- B. Plants
- C. All animals
- D. Some Plants
Correct Answer

A. A. Humans, but not for most other animals

Explanation

Ascorbic acid, also known as Vitamin C, is a vitamin that is essential for humans but not for most other animals. Humans lack the enzyme necessary to produce ascorbic acid in their bodies, so they must obtain it through their diet. Other animals, such as most mammals, can produce ascorbic acid internally and do not require it in their diet. Therefore, ascorbic acid is specifically used by humans and not necessary for most other animals.

The largest number of vitamins, the B complex vitamins, functions as what?
- A. Parasite cofactors
- B. Enzyme cofactors
- C. Cells cofactors
- D. Sugar factor
Correct Answer

A. B. Enzyme cofactors

Explanation

The B complex vitamins are a group of water-soluble vitamins that play a crucial role in the body's metabolism. They function as enzyme cofactors, meaning they assist enzymes in carrying out various chemical reactions in the body. Enzymes are proteins that catalyze biochemical reactions, and cofactors are non-protein molecules that help enzymes function properly. Therefore, the B complex vitamins act as essential components of enzymes, facilitating their ability to catalyze reactions and support metabolic processes in the body.

When is an organic compound said to be a vitamin?
- A. When the organism cannot break down
- B. When the organism is moving
- C. When the organism cannot synthesize the compound in sufficient quantities
- D. When the organic compound develops
Correct Answer

A. C. When the organism cannot synthesize the compound in sufficient quantities

Explanation

An organic compound is said to be a vitamin when the organism cannot synthesize the compound in sufficient quantities. This means that the organism is unable to produce enough of the compound on its own and therefore needs to obtain it from external sources, such as food or supplements. Vitamins are essential for various biological processes and functions in the body, and their deficiency can lead to various health problems. Therefore, when an organism is unable to synthesize a specific compound in sufficient quantities, that compound is considered a vitamin for that organism.
