Aerobic Anaerobic
1. Complete breakdown - Partial breakdown.
of glucose
2. Net gain 38 ATP - Net gain 2 ATP.
3. Vigrously - NADH oxidised slowly
4. CO2 released - No CO2 released.
Statement - 1 : Respiration is amphibolic pathway.
Statement - 2 : Pure fat & pure protein can never be
respiratory substrate.
Option :
1. Only second statement is correct.
2. Both statements are correct.
3. Neither first nor second is correct.
4. Only first statement is correct
When tripalmitin is used as substrate in respiration, the value of RQ is found to be less than one because
1. | It contains less number of carbon atoms than oxygen atoms. |
2. | The amount of CO2 evolved is more than the amount of O2 consumed. |
3. | The amount of O2 consumed is more than the amount of CO2 evolved. |
4. | The ratio of the numbers of carbon and hydrogen atoms in this molecule is not 1 : 2. |
Where is the respiratory electron transport system (ETS) located in plants?
1. Mitochondrial matrix
2. Outer mitochondrial membrane
3. Inner mitochondrial membrane
4. Intermembrane space
If RQ is 0.6 in a respiratory metabolism, it would mean that
1. Carbohydrates are used as respiratory material
2. Organic acids are used as respiratory substrate
3. The oxidation of the respiratory substrate consumed more oxygen than the amount of CO released
4. The oxidation of respiratory substrate consumed less oxygen than the amount of CO2 released
