Vitamins Part 2

What type of compunds are vitamins

• • Organic

• • Streroid

• • Non-organic

• • Complex organic

Answer explanation

Explanation
Vitamins are classified as complex organic compounds. This is because they are organic molecules that are essential for the proper functioning of the body. They are complex in nature because they contain multiple carbon atoms and often have intricate structures. Additionally, vitamins are required in small amounts for various metabolic processes and cannot be synthesized by the body in sufficient quantities, hence they need to be obtained through diet or supplementation.

How do plants manufacture vitamins

• • Photosynthesis

• • From the soil

• • Water absorbtion

Answer explanation

Explanation
Plants manufacture vitamins through the process of photosynthesis. During photosynthesis, plants use sunlight, carbon dioxide, and water to produce glucose, which is then converted into various vitamins and other organic compounds. This process occurs in the chloroplasts of plant cells, where chlorophyll captures sunlight energy and converts it into chemical energy. Therefore, photosynthesis is the correct answer as it explains how plants produce vitamins.

Vitamins can supply energy and contribute to body mass

• True

• False

Answer explanation

Explanation
Vitamins do not supply energy to the body. They are essential nutrients that help the body carry out various functions such as growth, development, and metabolism. While vitamins are necessary for overall health, they do not directly contribute to body mass or provide energy in the form of calories. Energy is primarily obtained from macronutrients like carbohydrates, fats, and proteins. Therefore, the statement that vitamins can supply energy and contribute to body mass is false.

Excess fat soluble vitamins intake has a high potential for toxicity

• True

• False

Answer explanation

Explanation
Excess intake of fat-soluble vitamins can lead to toxicity because these vitamins are stored in the body's fat tissues and can accumulate to harmful levels. Unlike water-soluble vitamins that are easily excreted in urine, fat-soluble vitamins (A, D, E, and K) are not easily eliminated from the body. Therefore, consuming excessive amounts of these vitamins through supplements or fortified foods can result in a buildup of toxic levels, causing adverse effects on health. It is important to consume these vitamins in moderation and consult a healthcare professional for proper dosage.

Water soluble vitamins in excess have a low potential for toxicity

• True

• False

Answer explanation

Explanation
Water-soluble vitamins, such as vitamin C and the B vitamins, are easily absorbed and excreted by the body. Unlike fat-soluble vitamins, they are not stored in large amounts in the body and any excess is typically eliminated through urine. This means that consuming excessive amounts of water-soluble vitamins is unlikely to lead to toxicity. Therefore, the statement that water-soluble vitamins in excess have a low potential for toxicity is true.

• B1 vitamins is

• • Riboflavin

• • Niacin

• • Biotin

• • Thiamin

Answer explanation

Explanation
Thiamin is the correct answer because it is one of the B1 vitamins. B1 vitamins are a group of water-soluble vitamins that play a crucial role in energy metabolism and the functioning of the nervous system. Thiamin, also known as vitamin B1, helps convert food into energy and is essential for the proper functioning of the heart, muscles, and nervous system. It is commonly found in foods such as whole grains, legumes, nuts, and pork.

• Vitamin B2 is also known as

• • Riboflavin

• • Biotin

• • Folic acid

• • Thiamin

Answer explanation

Explanation
Vitamin B2 is also known as riboflavin.

• Vitamin B3 is

• • Pyrodoxine

• • Folic acid

• • Niacin

• • Cobalin

Answer explanation

Explanation
Niacin is a form of vitamin B3. It plays a vital role in converting food into energy and helps maintain the health of the nervous system, skin, and digestive system. Niacin also helps lower cholesterol levels and can be found in various foods such as meat, fish, nuts, and grains. It is an essential nutrient for overall health and well-being.

• 
  Vitamin B5 is also known as

• • Biotin

• • Folic acid

• • Cobalin

• • Pantothenic acid

Answer explanation

Explanation
Vitamin B5 is also known as pantothenic acid. Biotin is a different vitamin, also known as vitamin B7. Folic acid is another vitamin, known as vitamin B9. Cobalin is not a known name for any vitamin. Therefore, the correct answer is pantothenic acid.

• Vitamin B6 is

• • Thiamin

• • Pyridoxine

• • Cobalin

• • Riboflavin

Answer explanation

Explanation
Pyridoxine is a form of vitamin B6. It is essential for the metabolism of proteins, carbohydrates, and fats in the body. It plays a crucial role in the production of neurotransmitters, such as serotonin and dopamine, which are important for mood regulation. Pyridoxine also supports the immune system, helps in the formation of red blood cells, and promotes healthy brain development. Thiamin, cobalin, and riboflavin are different forms of B vitamins, but they are not synonymous with vitamin B6.
