Nutritional Value Of Meat Quiz

Meat is a major source of protein because it contains high levels of essential amino acids, which are the building blocks of protein. Protein is crucial for various functions in the body, such as muscle growth and repair, hormone production, and immune system function. Additionally, meat is a complete protein source, meaning it provides all the essential amino acids that the body cannot produce on its own. Therefore, consuming meat helps meet the body's protein requirements and supports overall health and well-being.

Myoglobin is present in relatively large quantities in the heart muscle because of its heavy oxygen demand. The heart muscle requires a constant supply of oxygen to function properly and pump blood throughout the body. Myoglobin is a protein that stores and transports oxygen in muscle tissues, allowing the heart muscle to extract oxygen from the blood and use it efficiently. Therefore, the high concentration of myoglobin in the heart muscle helps meet its oxygen demands and maintain its optimal function.

The given answer B is correct because meat is indeed a good source of vitamins. Meat, especially lean meats like chicken and turkey, contains essential vitamins such as vitamin B12, vitamin B6, and niacin. These vitamins are important for various bodily functions including energy production, brain function, and the formation of red blood cells. Therefore, including meat in one's diet can help ensure an adequate intake of vitamins.

Meat is a good source of iron and zinc because these minerals are naturally present in meat. Iron is essential for the formation of red blood cells and helps transport oxygen throughout the body. Zinc plays a crucial role in various bodily functions, including immune system function, wound healing, and DNA synthesis. Both iron and zinc are important for overall health and can be easily obtained from meat consumption.

The liver is the correct answer because it is the organ that stores the highest amount of vitamin A. Vitamin A is a fat-soluble vitamin that is stored in the liver and released into the bloodstream as needed. It plays a crucial role in maintaining healthy vision, immune function, and cell growth. While other organs may contain some amount of vitamin A, the liver is the primary storage site, making it the richest source of this vitamin.

The period of birth does not affect meat quality because it refers to the time when an animal is born, which does not have a direct impact on the quality of the meat. Factors such as age, breed, feeding, and gender can all influence the quality of meat, but the period of birth itself does not play a significant role in determining meat quality.

The correct answer is 75% because it is stated in the question that the average moisture content in meat is 75%.

The average protein content in meat is 20%. This means that, on average, 20% of the total weight of the meat is made up of protein.

Oleic acid is a monounsaturated fatty acid. It is commonly found in various plant and animal sources, such as olive oil, avocados, and nuts. Monounsaturated fatty acids have one double bond in their chemical structure, which gives them a more fluid consistency at room temperature compared to saturated fats. Oleic acid is known for its potential health benefits, including reducing inflammation, improving heart health, and supporting weight management.

"Marbled" meat refers to meat that has visible streaks or flecks of fat running through the lean muscle. This fat is distributed evenly throughout the meat, adding flavor and tenderness. The correct answer of 4-8% indicates that marbled meat contains 4-8% of fat by weight of lean meat. This means that for every 100 grams of marbled meat, 4-8 grams will be fat, while the remaining 92-96 grams will be lean meat.
