Vitamins do not provide energy themselves; they help to release energy from carbs, proteins, & fats that are ingested
-
True
-
False
Correct Answer
A. TrueExplanation
Vitamins are essential nutrients that the body needs in small amounts to function properly. While they do not directly provide energy, they play a crucial role in the process of releasing energy from the macronutrients (carbohydrates, proteins, and fats) that we consume. Vitamins act as coenzymes, which means they assist enzymes in the breakdown of these macronutrients, allowing the body to extract energy from them. Therefore, it is true that vitamins do not provide energy themselves but help in the energy release process.Rate this question:

An excess of one vitamin or mineral can negatively affect the absorption or utilization of other vitamins & minerals.
-
True
-
False
Correct Answer
A. TrueExplanation
Excess intake of one vitamin or mineral can interfere with the absorption or utilization of other vitamins and minerals. This is because certain vitamins and minerals compete for the same transporters or binding sites in the body. For example, excessive intake of zinc can interfere with the absorption of copper, while excessive intake of calcium can inhibit the absorption of iron. Therefore, it is important to maintain a balanced intake of vitamins and minerals to ensure proper absorption and utilization by the body.Rate this question:

Deficiency disease caused by lack of vitamin D; causes malformed bones in infants
-
Osteomalacia
-
Osteoporosis
-
Rickets
Correct Answer
A. RicketsExplanation
Rickets is a deficiency disease caused by a lack of vitamin D. It primarily affects infants and leads to the formation of malformed bones. This condition occurs when the body is unable to absorb enough calcium and phosphorus, which are essential for bone development. As a result, the bones become weak and soft, leading to deformities. Osteomalacia is a similar condition that affects adults, causing weak and brittle bones. Osteoporosis, on the other hand, is a condition characterized by low bone density and increased risk of fractures, but it is not caused by a lack of vitamin D.Rate this question:

A. Pernicious anemiaExplanation
Pernicious anemia is a type of severe, chronic anemia caused by a deficiency in vitamin B12. It is usually due to the body's inability to absorb B12 properly. This can occur when the stomach does not produce enough intrinsic factor, a protein that helps with B12 absorption. Without enough B12, the body is unable to produce enough healthy red blood cells, leading to symptoms such as fatigue, weakness, and shortness of breath. Megoblastic anemia is also a type of anemia, but it is not specifically associated with a deficiency in B12.Rate this question:
