Question 1
1 / -0

The end products of fermentation when sugar is used as raw materials is/are

A
Alcohol and $$CO_2$$.

B
Alcohol and pyruvate.

C
$$CO_2$$.

D
Alcohol.

Solution

The respiration process can be aerobic or anaerobic. In both the processes glycolysis, which occurs in absence of oxygen is common. Glycolysis converts one molecule of glucose into two molecules of pyruvic acid. Glycolysis occurs in cell cytoplasm. The anaerobic respiration is a cytosolic process, which results in production of lactic acid (lactic acid fermentation) or ethanol and carbon dioxide (alcoholic fermentation).
Question 2
1 / -0

Which of the following is not an intermediate of Krebs cycle?

A
Acetyl CoA

B
Citric acid

C
Succinic acid

D
Lactic acid

Solution

Lactic acid is never a part of citric acid cycle. Acetyl Co A, citric acid and succinic acid are part of citric acid cycle. Lactic acid is produced in anaerobic respiration in muscles. Thus, the correct answer is option D.
Question 3
1 / -0

Mechanism of aerobic respiration was discovered by

A
Kreb

B
Calvin

C
Hatch and Slack

D
Pasteur

Solution

Mechanism of aerobic respiration was given by Kreb. Thus it was named as Krebs cycle. Aerobic respiration is the respiration, which involves the breakdown of the substrate in the presence of oxygen (oxidation process).
Question 4
1 / -0

Glycolysis occurs

A
In cytoplasm

B
In aerobic respiration

C
In anaerobic respiration

D
All of the above

Solution

Glycolysis process involves both aerobic and anaerobic respiration. Glycolysis is the complete oxidation of glucose molecule. It is also called as EMP pathway. It takes place in the cytoplasm. It breaks the glucose into pyruvate. It leads to the production of 8 ATP.
So, the correct answer is option D.
Question 5
1 / -0

Which group of the following scientists discovered the EMP pathway or glycolysis?

A
Embden, Meyerhof and Parnas

B
Embden, Hoffman and Peterson

C
Embden, Morrison and Pitcher

D
Avery, McLeod and McCarthy

Solution

Glycolysis is also called as EMP pathway. It was named after the discoverers Embden, Meyerhof and Parnas. It is the common process involved in the aerobic and anaerobic respiration.
Question 6
1 / -0

The experiment to show that $$CO_{2}$$ is given out during respiration, the type of respiration is

A
anaerobic

B
aerobic

C
both (a) and (b)

D
neither (a) and (b)
Question 7
1 / -0

The common phase between aerobic and anaerobic respiration is called:

A
Tricarboxylic acid cycle

B
Oxidative phosphorylation

C
Embden, Meyerhoff, Parnas cycle

D
Krebs cycle

Solution

The common phase between aerobic and anaerobic respiration is glycolysis, which is also called the EMP pathway. It is named after the discoverers Embden, Meyerhoff and Parnas.
Question 8
1 / -0

Alternate name for Krebs cycle is

A
Glyoxylate cycle.

B
Glycolate cycle.

C
Citric acid cycle.

D
EMP pathway.

Solution

The Krebs cycle occurs in the mitochondrial matrix and as the first stable product of Krebs cycle is citric acid, it is also called as the citric acid cycle.
Question 9
1 / -0

Fermentation by yeast produces
I. Carbon dioxide
II. Oxygen
III. Water
IV. Alcohol

A
I only

B
I and II

C
I, II and III

D
I, III and IV

E
I and IV

Solution

Fermentation is a metabolic process occurs in yeast and bacteria. It occurs in the absence of oxygen. The products produced by yeast includes carbon dioxide, water and ethanol. Glycolysis is the first step of fermentation pathways as well which produces pyruvate, however other steps Kreb's cycle etc. does not take place in the absence of oxygen. Hence option D is correct.
This process is extensively used in alcohol industry.
Question 10
1 / -0

Which of the following processes utilizes a proton pump?

A
Glycolysis

B
Fermentation

C
Krebs cycle

D
Electron transport chain

E
Photosynthesis

Solution

The proton pump is the process of creating a proton gradient across the membrane. During the process of Electron transport chain, protons physically move across the membrane to create an electrochemical gradient that helps in the synthesis of ATP form ATP synthetase. This proton pump is not created in the other four processes.
