If we consider the average composition of cells the correct descending order of the components will be:
1. Proteins → Nucleic acids → Carbohydrates → Lipids
2. Proteins → Carbohydrates → Nucleic acids → Lipids
3. Lipids → Carbohydrates → Nucleic acids → Proteins
4. Carbohydrates → Proteins → Lipids → Nucleic acids
Consider the given two statements:
Statement I: | A protein is a heteropolymer. |
Statement II: | There are 20 types of proteinogenic amino acids and they are linked by peptide bonds to form polypeptides. |
1. Only Statement I is correct
2. Only Statement II is correct
3. Both Statement I and Statement II are correct
4. Both Statement I and Statement II are incorrect
Statement 1: | Certain amino acids are essential for our health. |
Statement 2: | Only such amino acids are used to make proteins in our body according to our own genetic code. |
1. | Both Statement 1 and Statement 2 are correct and Statement 2 correctly explains Statement 1 |
2. | Both Statement 1 and Statement 2 are correct but Statement 2 does not correctly explain Statement 1 |
3. | Statement 1 is correct but Statement 2 is incorrect |
4. | Statement 1 is incorrect but Statement 2 is correct |
I: | GLUT-4 | Enables glucose transport out of the cells |
II: | Collagen | Most abundant protein in animal world |
III: | RuBisCO | Most abundant protein in the whole of the biosphere |
1. | Only I | 2. | Only I and II |
3. | Only I and III | 4. | Only II and III |
Statement I: | The right end of the glycogen molecule is called the reducing end and the left end is called the non-reducing end. |
Statement II: | Glycogen is a homopolymer of alpha glucose. |
Statement I: | Iodine test can detect the presence of starch but not of cellulose in a given sample. |
Statement II: | Starch forms helical secondary structure and can hold iodine molecules while cellulose does not contain complex helices and hence cannot hold iodine. |
1. | Both Statement I and Statement II are correct and Statement II correctly explains Statement I |
2. | Both Statement I and Statement II are correct but Statement II does not correctly explain Statement I |
3. | Statement I is correct but Statement II is incorrect |
4. | Statement I is incorrect but Statement II is correct |
1. | Nucleic acids | 2. | Polysaccharides |
3. | Lipids | 4. | Proteins |
1. | Thymine | 2. | Uracil |
3. | Adenine | 4. | Guanine |
I | II | |
1. | 2’ deoxyribose | Ribose |
2. | Ribose | 2’ deoxyribose |
3. | Adenosine | Adenylic acid |
4. | α glucose | β glucose |
