The major ways through which different cells handle Pyruvate of Glycolysis are except
(1) Lactic Acid Fermentation
(2) Alcoholic Fermentation
(3) Aerobic Respiration
(4) Phosphorespiration
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
Aerobic Respiration:
(1) More common in higher organisms
(2) Leads to complete oxidation of Organic substance in the presence of oxygen and release of Carbon-dioxide
(3) Large amount of energy present in substrate and amount of water is also released out
(4) All of these
The events of Aerobic Respiration include:
| p. | The complete oxidation of Pyruvate by the stepwise removal of all the hydrogen atoms leaving two molecules of Carbon-dioxide |
| q. | The passing on of the electrones removed as part of the Hydrogen atoms to molecular oxygen with simultaneous synthesis of ATP |
| r. | Pyruvate is transported from Cytoplasm to Matrix |
| s. | Two events of Aerobic Respiration takes place within mitochondria. |
| t. | The first process takes place in the matrix of mitochondria while second process is located on the inner membrane of mitochondria |
The correct ones are
| 1. | pqrst | 2. | qrst |
| 3. | pqrs | 4. | prs |
