Sugars are not as good as fats as a source of energy for cellular respiration, because sugars.

  1. Produce toxic amino groups when broken down

  2. Contain more hydrogen

  3. Usually bypass glycolysis and the Krebs cycle

  4. Contain fewer hydrogen atoms and electrons


Correct Option: A
Explanation:

Sugars, when broken down, produces toxic amino groups. During Cellular Respiration, sugar is broken down to CO$ _2$and H$ _2$O, and in the process, ATP is made that can then be used for cellular work. Carbohydrates, fats, and proteins can all be used as fuels in cellular respiration, but glucose is most. In glycolysis, the 6-carbon sugar, glucose, is broken down into two molecules.

So the correct answer is 'Produce toxic amino groups when broken down'.

Which of the following is not directly dependent of a person's protein intake?

  1. Formation of enzymes

  2. Formation of glycogen stored in liver

  3. Production of antibodies in the immune system

  4. Production of muscle tissues


Correct Option: B
Explanation:

Considering all the four options we find that Enzymes, Antibodies and Muscle tissue all are made up of amino acids as their basic structural component only the glycogen stored in the liver is made up of monosaccharides as it's structural component. So, protein intake in the person will affect the formation of enzymes, antibodies and muscle tissue but will not affect the Glycogen stores in the Liver.

So, the correct answer to the question is 'Formation of the glycogen store in the liver'. 

A person is eating rice. His food contains

  1. Cellulose

  2. Starch

  3. Lactose

  4. Protein


Correct Option: B
Explanation:

Cereals like wheat, rice, maize etc., are good source of carbohydrates. They contain starch as reserve food in their endosperm. The starch is a polymer of glucose.

Meat, milk and eggs mainly supply us with

  1. Hormones

  2. Carbohydrates

  3. Proteins

  4. Fats


Correct Option: C
Explanation:

Proteins are the major body building biomolecules. Proteins serve a variety of structural and functional roles. Meat, milk and eggs are an important source of proteins. Soybean and other pulses are an important source of plant proteins.

Man needs carbohydrates as a source of energy and gets these from

  1. Starch

  2. Cellulose

  3. Both A and B

  4. None of the above


Correct Option: A
Explanation:

Carbohydrates are a source of energy and primary cellular fuel. Cereals like rice, wheat, maize are a primary source of carbohydrate for man. Humans can digest starch present in cereals but not cellulose. Hence, dietary starch is broken down into glucose inside the body which provides us with energy.

Therefore, the correct answer is option A.

Which of the following has maximum proteins?

  1. Rice

  2. Wheat

  3. Gram

  4. Soyabean


Correct Option: D
Explanation:

Rice and Wheat are cereals belonging to Family Poaceae. They are rich in carbohydrates. Gram and Soybean are legumes of Family Leguminosae. Legumes are rich in proteins. Soyabean is also an important oilseed crop. Among legumes Soyabean are richest source of proteins. Together, soyabean oil and protein content account for about 60% of dry soyabeans by weight (protein at 40% and oil at 20%).

Which of the following plants are rich sources of dietary protein?

  1. Cajanus cajan

  2. Solanum nigrum

  3. Tridax procumbens

  4. Oryza sativa


Correct Option: A
Explanation:

Cajanus cajan is a puise seed crop and belongs to family Leguminosae. Its english name is pigeon pea and is commonly called Arhar or Toor in hindi. Being a pulse seed crop it is rich in proteins.

In whose milk, percentage of lactose is highest?

  1. Human mother

  2. Cow

  3. She buffallo

  4. She goat


Correct Option: A
Explanation:

The percentage of lactose in milk varies with species. Human milk has a high lactose content, the percentage of lactose in human milk ranges from 6.5 to 7.5%. Unprocessed cow milk has about 4.7% lactose, unprocessed goat milk has about 4.7% lactose, unprocessed buffalo milk has about 4.86% lactose. The average in cow and goat milk is less than 5% and vary according to the breed. When human babies are reared on cow or goat milk, it is customary to add lactose, sucrose, glucose, or malto-dextrin in their feed.

Excessive intake of alcohol causes

  1. Jaundice

  2. Dermatitis

  3. Liver cirrhosis

  4. Lung Fibrosis


Correct Option: C
Explanation:

Cirrhosis is an abnormal liver condition in which there is irreversible scarring of the liver. People with cirrhosis may develop jaundice, itching and extreme tiredness. When liver tries to break down alcohol, the resulting chemical reaction damage its cells. This damage can lead to inflammation and scarring as the liver tries to repair itself.

The most common concentrated source of proteins for vegetarians in our country is

  1. Potatoes

  2. Meat

  3. Eggs

  4. Pulses


Correct Option: D
Explanation:

Meat, eggs and pulses are good sources of proteins. Proteins are body building substances and are an important part of a balanced diet. For vegetarian people pulses can be a good source of proteins. Our country produces a variety of 'dals' and these can be consumed as protein sources.
