Sucrose is converted into glucose and fructose by the enzyme:
1. Sucrase | 2. Aldolase |
3. Invertase | 4. Zymase |
Assertion (A): | Glycolysis occurs in the cytoplasm of plant cells. |
Reason (R): | Glycolysis does not require oxygen, making it an anaerobic process. |
1. | Both (A) and (R) are True and (R) is the correct explanation of (A). |
2. | Both (A) and (R) are True but (R) is not the correct explanation of (A) |
3. | (A) is True but (R) is False. |
4. | (A) is False but (R) is True. |
A: | ATP production takes place by substrate-level phosphorylation. |
B: | ATP is used and produced. |
C: | The end products are carbon dioxide and water. |
Phosphorylation of glucose during glycolysis is catalysed by
1. Phosphoglucomutase | 2. Phosphoglucoisomerase |
3. Hexokinase | 4. Phosphorylase |
The number of metabolic steps in EMP pathway where glucose undergoes partial oxidation to form two molecules of pyruvic acid is:
1. 8 | 2. 9 |
3. 10 | 4. 11 |
What is the end product of glycolysis?
1. NADH | 2. ATP |
3. G3P | 4. Pyruvate |
1. | during conversion of 1,3 biphosphoglyceric acid to 3-phosphoglyceric acid and during conversion of phosphoenolpuruvate to pyruvic acid |
2. | during conversion of glucose to glucose-6-phospate and during conversion of fructose-6-phosphate to fructose – 1,6- biphosphate |
3. | during conversion of glucose to glucose-6-phospate and during conversion of glucose-6-phosphate to fructose-6- phosphate |
4. | during conversion of 3-phosphoglyceric acid to 2-phosphoglycerate and during conversion of 2-phosphoglycerate to phosphoenolpuruvate |
The net gain of number of ATP molecules during glycolysis will be:
1. 2 | 2. 4 |
3. 6 | 4. 8 |
1. | during conversion of 1,3 biphosphoglyceric acid to 3-phosphoglyceric acid |
2. | during conversion of glyceraldehyde -3-phosphate to 1,3 biphosphoglyceric acid |
3. | during conversion of glucose to glucose-6-phospate |
4. | during conversion of 3-phosphoglyceric acid to 2-phosphoglycerate |
