1.
How many kilograms of red meats per serving is required according to the Canada's food guide.
Correct Answer
B. .075
Explanation
According to Canada's food guide, only 0.075 kilograms of red meats per serving is required.
2.
Which of the following is not enriched in red meats.
Correct Answer
C. Sodium
Explanation
Red meats are generally high in zinc, omega-3 fatty acids, and selenium, which are all essential nutrients. However, sodium is not specifically enriched in red meats. While red meats do contain some sodium, it is not significantly higher compared to other food sources. Therefore, sodium is not considered to be enriched in red meats.
3.
Iron from red mets help in
Correct Answer
B. Transport of oxygen through artery
Explanation
Iron is an essential component of hemoglobin, a protein found in red blood cells that is responsible for transporting oxygen throughout the body. Arteries are blood vessels that carry oxygenated blood away from the heart to the various tissues and organs. Therefore, iron from red meats helps in the transport of oxygen through arteries.
4.
More than half of human brains consist of
Correct Answer
B. Saturated fat and cholesterol
Explanation
The correct answer is "saturated fat and cholesterol." This is because saturated fat and cholesterol are major components of the human brain. Omega-3 fat is also present in the brain, but it does not make up more than half of the brain. Unsaturated fat and protein are not the dominant components of the brain.
5.
Niacin is the other name of vitamin
Correct Answer
B. B-3
Explanation
Niacin is commonly known as vitamin B-3. It is an essential nutrient that plays a crucial role in energy production, DNA repair, and the functioning of the nervous system. Niacin is also important for maintaining healthy skin, digestive system, and cardiovascular health. It can be obtained from various food sources like meat, fish, legumes, and whole grains. Deficiency of niacin can lead to a condition called pellagra, which is characterized by symptoms like dermatitis, diarrhea, and dementia. Therefore, the correct answer is B-3.
6.
What is the closest percentage of saturated fats and cholesterol in human brains
Correct Answer
B. 25 x 2
Explanation
The closest percentage of saturated fats and cholesterol in human brains is 25 x 2.
7.
Which of the following help in chemical and fat breakdown.
Correct Answer
C. Selenium
Explanation
Selenium is a trace mineral that plays a crucial role in various biochemical processes in the body, including the breakdown of chemicals and fats. It acts as a cofactor for certain enzymes involved in these processes, helping to facilitate the chemical reactions necessary for breakdown. Iron, zinc, and sodium also have important roles in the body, but they are not specifically known for aiding in chemical and fat breakdown.
8.
Formation of which of the following occurs from vitamin B-12
Correct Answer
B. Blood cells
Explanation
Vitamin B-12 plays a crucial role in the formation of blood cells. It is required for the production of red blood cells, which are responsible for carrying oxygen throughout the body. Without adequate levels of vitamin B-12, the production of red blood cells can be impaired, leading to a condition called vitamin B-12 deficiency anemia. This can result in fatigue, weakness, and other symptoms related to insufficient oxygen supply in the body. Therefore, the correct answer is blood cells.
9.
Which of following helps in tissue formation and metabolism
Correct Answer
B. Zinc
Explanation
Zinc is an essential mineral that plays a crucial role in tissue formation and metabolism. It is required for the synthesis of DNA, protein, and collagen, which are important for the growth and repair of tissues. Zinc also acts as a cofactor for many enzymes involved in various metabolic processes, including carbohydrate, protein, and lipid metabolism. Therefore, zinc is necessary for proper tissue development and maintenance, as well as for the efficient functioning of metabolic pathways.
10.
What is the percentage of saturated fats of the total fats in human brain
Correct Answer
B. 25 x 2
Explanation
The answer 25 x 2 suggests that the percentage of saturated fats of the total fats in the human brain is 50%. This means that half of the total fats in the brain are saturated fats.
11.
Saturated fat in red meat cell activate which of following reaction
Correct Answer
B. Oxidation
Explanation
Saturated fat in red meat cells activate the oxidation reaction. Oxidation is a chemical process in which a substance loses electrons, resulting in the formation of a new compound. In the case of saturated fat in red meat cells, oxidation can occur when the fat is exposed to oxygen, leading to the breakdown of the fat molecules and the release of energy. This process is commonly observed when cooking red meat, as the heat and oxygen cause the fat to oxidize, resulting in browning and flavor development.
12.
Which of the following represents a large portion of the formation of myelin sheath
Correct Answer
B. Saturated fat and cholesterol
Explanation
Saturated fat and cholesterol represent a large portion of the formation of myelin sheath. Myelin sheath is a protective covering around nerve fibers in the body, and it is composed mainly of lipids, including saturated fat and cholesterol. These lipids provide insulation and support for nerve impulses, allowing for efficient communication between neurons. Omega-3 fat and unsaturated fat are also important for overall brain health, but they do not play as significant a role in the formation of myelin sheath as saturated fat and cholesterol do. Omega-3 fat and proteins are not directly involved in the formation of myelin sheath.
