Q. No.In the absence of oxygen, the primary purpose of fermentation is to:
| 1. | produce amino acids for protein synthesis |
| 2. | generate a proton gradient for ATP synthesis |
| 3. | oxidize glucose to generate reduce electron carriers |
| 4. | regenerate NAD+ from NADH allowing glycolysis to continue |
The useful purpose served by lactate fermentation is:
| 1. | Make lactose available for gluconeogenesis |
| 2. | Production of additional ATP in anaerobic conditions |
| 3. | Regeneration of NAD+ |
| 4. | Increased availability of oxygen for the skeletal muscle |
In which one of the following processes CO2 is not released?
1. Aerobic respiration in plants
2. Aerobic respiration in animals
3. Alcoholic fermentation
4. Lactate fermentation
The energy-releasing metabolic process in which substrate is oxidised without an external electron acceptor is called
1. glycolysis
2. fermentation
3. aerobic respiration
4. photorespiration
Fermentation can take place in
1. Anaerobic conditions in many prokaryotes and unicellular Eukaryotes
2. Humans
3. Cancer cells
4. All of these
The enzymes involved in Alcoholic Fermentation is not
1. Pyruvate decarboxylase
2. Alcohol dehydrogenase
3. Lactate dehydrogenase
4. Hexokinase
Which of the following acts as a reducing agent in Fermentation?
1. NADH + H+
2. NAD+
3. Lactate
4. Alcohol
Alcoholic Fermentation is observed in case of
1. Muscles undergoing vigorous exercise
2. Anaerobic Bacteria
3. Yeast
4. Cancer cells
In Fermentation
1. The amount of energy trapped in the form of ATP is 7per cent of the energy in Glucose
2. The amount of energy trapped in the form of ATP is more than 7 per cent of the energy in Glucose
3. The amount of energy released is less than 7 per cent of the energy stored in Glucose
4. The amount of energy released is more than 7 per cent of the energy stored in Glucose
If an yeast performs Fermentation such that the concentration of the Alcohol reaches to ………, then it posions itself to ……..
1. 7 per cent, the stage of no budding
2. 5 per cent, the stage of no budding
3. 13 per cent, death
4. 10 per cent, death
