Question 1
1 / -0

The net gain of ATP in EMP pathway is

A
24 ATP molecules

B
8 ATP molecules

C
38 ATP molecules

D
6 ATP molecules

Solution

EMP pathway is also called as Embden–Meyerhof–Parnas or glycolysis cycle. 4 ATP is formed in the pay off phase and six ATP is regenerated from the two NAD $^+$ molecules. So, the total gain of ATP is 10 ATP. Out of which to are utilized in the preparatory phase so the net gain is 8 ATP.
Thus, the correct answer is '8 ATP molecules.'
Question 2
1 / -0

The enzyme which converts glucose to glucose-6-phosphate is

A
Phosphorylase

B
Glucose-6-phosphate

C
Hexokinase

D
Glucose synthetase

Solution

The glucose is converted to glucose 6 phosphate by enzyme hexokinase which is found in most of the cytoplasm of the cell but in some cells, glucokinase enzyme is also present which catalyse glucose to glucose 6 phosphate.
So the correct option is 'hexokinase'.
Question 3
1 / -0

The number of pyruvic acid molecules formed from one molecule of glucose at the end of glycolysis is

A
1

B
2

C
3

D
4

Solution

2 molecules of three carbon pyruvic acid is formed from one molecule of glucose (6-carbon) at the end of glycolysis. There is a net gain of 8 ATP molecules as a result of glycolysis.
Question 4
1 / -0

The net gain of ATP by 8 molecules of glucose through glycolysis is

A
24

B
56

C
64

D
None of the above
Question 5
1 / -0

The process of glycolysis can be represented as

A
$C_{6}H_{12}O_{6}\rightarrow 2C_{3}H_{4}O_{3}+4H$

B
$C_{6}H_{12}O_{6}+6CO_{2}\rightarrow 6CO_{2}+6H_{2}O$

C
$6H_{2}O+6CO_{2}\rightarrow C_{6}H_{12}O_{6}+6O_{2}$

D
None of the above

Solution

Glycolysis is the metabolic pathway, that converts one glucose molecule into two pyruvate. The free energy released in this process is used to form the high-energy compounds ATP and NADH.
Question 6
1 / -0

The first phase in the breakdown of glucose in animals cells is

A
Krebs cycle

B
Glycolysis

C
Electrons transport system

D
Lipid biosynthesis

Solution

Glycolysis is the initial step in the breakdown of glucose in animal cells. It takes place in the cytoplasm of cells. After glycolysis pyruvic acid enters into mitochondria and cycles through Krebs cycle.
Question 7
1 / -0

ATP formation in glycolysis is

A
Oxidative phosphorylation

B
Photophosphorylation

C
Reductive phosphorylation

D
Substrate level phosphorylation
Solution
- The process of ATP formation is phosphorylation.
- Substrate-level phosphorylation is a metabolism reaction that results in the production of ATP or GTP by the transfer of a phosphate group from a substrate directly to ADP or GDP.
- In the process of glycolysis, there is a net gain of 2 ATP molecules through substrate-level phosphorylation.
So, the correct answer is option D.
Question 8
1 / -0

Which of the following process occurs in glycolysis?

A
Oxidation

B
Reduction

C
Hydrogenation

D
Fixation

Solution

Glycolysis is the metabolic pathway, that converts glucose into pyruvate. In it oxidation of glucose is involved. The free energy released in this process is used to form the high-energy compounds ATP and NADH.
Question 9
1 / -0

Which one of the following product is formed during glycolysis of glucose?

A
Pyruvic acid

B
Carbon dioxide

C
Citric acid

D
Ethanol

Solution

Pyruvic acid is a product of glycolysis. It can be made from glucose through glycolysis. This the connecting compound of aerobic and anaerobic respiration.
Question 10
1 / -0

Which is common in respiration and photosynthesis?

A
Oxidation

B
Phytochrome

C
Cytochrome

D
Photosystem

Solution

Cytochromes are membrane-bound hemeproteins containing heme groups and are primarily responsible for the generation of ATP via electron transport. It is common in both photosynthesis as well as respiration.
