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 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
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
Which of the following is not the assumption considered to finalize the balance sheet of respiration?
(1) There is sequential, orderly pathway functioning with one substrate forming the next and with glycolysis following TCA and Then ETS pathway
(2) The NADH synthesized in Glucolysis is transferred into the mitochondria and undergoes Oxidative Phosphorylation
(3) No anabolism from respiratory intermediates.
(4) Glucose, Proteins and Fats are being respired altogether.
Fermentation-
Which of the following is true?
(1) Only partial breakdown of glucose
(2) Net gain of only two molecules of ATP for each molecule of Glucose
(3) NADH is oxidized to NAD+ rather slowly in fermentation
(4) All of these
