Show answer
Correct Option: C
Explanation:
Intentional or voluntary termination of pregnancy before full term is called medical termination of pregnancy (MTP) or induced abortion. MTPs are considered relatively safe during the first trimester, i.e., upto 12 weeks of pregnancy. Second trimester abortions are much more risker.
So, the correct option is 'Twelve'.

The ultimate source of energy in human beings is

biology food for health fats fats and their test different nutrients in food

  1. Fats

  2. Carbohydrates

  3. Proteins

  4. None of the above

Show answer
Correct Option: A
Explanation:

Fats are broken down into free fatty acids (FFA) and triglycerides which can produce ATP through chemical reactions.

Fatty acids either circulate in the blood or are stored as triglycerides in adipose tissue and muscle.
Fat is a very energy dense nutrient, one gram of it provides nine calories of energy. 
Despite the large quantity of available energy that fat has it provides this energy at a much slower rate than carbohydrate. This is because the chemical reactions required for its breakdown are much more complex and time consuming. 

Which of the following has the highest calories per gram?

  1. Proteins

  2. Fats

  3. Sugar

  4. Glucose

Show answer
Correct Option: B
Explanation:

Calories are needed to provide energy so the body functions properly. The number of calories in a food depends on the amount of energy the food provides. The number of calories a person needs depends on age, height, weight, gender, and activity level. People who consume more calories than they burn off in normal daily activity or during exercise are more likely to be overweight.

The amount of energy one will get from carbohydrate, protein and fat is measured in calories per gram. Fats have the most energy and proteins have the same amount as carbohydrates, but their value as a source of energy is determined by more than the calories gained from one gram.
Fat: 1 gram = 9 calories 
Protein: 1 gram = 4 calories 
Carbohydrates: 1 gram = 4 calories

Therefore, the correct answer is option B.

Saturated fat is

  1. Solid at room temperature

  2. Has fatty acids with no double bonds between the carbon atoms

  3. Is of animal origin.

  4. All of the above

Show answer
Correct Option: D
Explanation:

Saturated fats are simply fat molecules that have no double bonds between carbon molecules because they are saturated with hydrogen molecules. These are typically solid at room temperature and are found in animals.

So the correct option is 'All of the above'.

Which fat soluble vitamin helps in synthesis of prothrombin?

  1. Vitamin K

  2. Vitamin A

  3. Vitamin E

  4. Vitamin C

Show answer
Correct Option: A
Explanation:

Vit B & C are water-soluble. Vit K is fat-soluble required for the formation of many clotting factor-like prothrombin. Vit A is also fat-soluble.

Which compound produces more than twice the amount of energy as compared to carbohydrates?

biology food for health fats fats and their test different nutrients in food

  1. Protein

  2. Fats

  3. Vitamins

  4. Glucose

Show answer
Correct Option: B
Explanation:

Carbohydrates are the primary fuel used in cellular metabolism. Excess carbohydrates are stored as glycogen and fats. The fats are a very concentrated source of energy. One gram of fat provides 8.8 kcal of energy as against 4.2 kcal provided by one gram of carbohydrate.

Carotenoids are composed of units called as

biology food for health fats fats and their test different nutrients in food

  1. Fatty acids

  2. Amino acids

  3. Isoprene

  4. Pyran

Show answer
Correct Option: C
Explanation:

Carotenoids are organic pigments that are found in the chloroplasts and chromoplasts of plants and some other photosynthetic organisms, including some bacteria and some fungi. Carotenoids can be produced from fats and other basic organic metabolic building blocks by all these organisms. All carotenoids are tetraterpenoids, meaning that they are produced from 8 isoprene molecules and contain 40 carbon atoms.
