Weekly Quiz Competition

Question 1
1 / -0

In mitochondria, cristae act as a site for

A
Protein synthesis

B
Oxidation-reduction reaction

C
Breakdown of macromolecules

D
Phosphorylation of flavoproteins

Solution

Mitochondrial cristae acts as sites for oxidation-reduction reaction. Cristae are folds of the inner mitochondrial membrane. The electron transport chain and chemiosmosis take place on this membrane as part of cellular respiration to create ATP.
So, the correct answer is option B.
Question 2
1 / -0

In carbon dioxide reduction, ATP is

A
Used

B
Unused

C
May be used or not used

D
None of the above

Solution

Light independent reactions of photosynthesis involve the reduction of carbon dioxide using reduced NADP and ATP produced in the light-dependent reaction of photosynthesis. The reactions are known as the Calvin cycle, and they take place in the stroma of the chloroplasts.
Therefore, the correct answer is option A.
Question 3
1 / -0

Which of the following is involved in the catalysis of link reaction during aerobic respiration?

A
Vitamin A

B
Vitamin $$B_{1}$$

C
Vitamin $$B_{6}$$

D
Vitamin K
Solution
1. Many of the vitamins needed by our bodies are used as coenzymes to help our enzymes to do their jobs. Vitamin $$B_1$$ is also called thiamine.
2. Thiamine pyrophosphate (TPP) is a cofactor that is present in all living systems and catalyzes several biochemical reactions.
3. In the pyruvate dehydrogenase complex that carries out the link reaction, TPP acts as a coenzyme.
So, the correct answer is 'Vitamin B$$_1$$'
Question 4
1 / -0

Aerobic respiratory pathway is appropriately termed

A
Catabolic

B
Parabolic

C
Amphibolic

D
Anabolic
Solution
- A metabolic pathway that participates in both anabolic and catabolic pathways is called amphibolic.
- The citric acid cycle (Krebs cycle) is a good example of the amphibolic pathway.
- The first reaction of the cycle, in which oxaloacetate (a four-carbon compound) condenses with acetate (a two-carbon compound) to form citrate (a six-carbon compound) is typically anabolic.
- The next few reactions are typically catabolic.
Question 5
1 / -0

Glycolysis occurs in

A
Generally in all the cells

B
In only eukaryotes

C
Only in prokaryotes

D
Only in higher animals

Solution

Glycolysis occurs in cytoplasm of cells in anaerobic as well as aerobic respiration.
Question 6
1 / -0

Harden and Young's ester is formed during glycolysis from

A
Fructose1,6-bisphosphate

B
Glucose-6-phosphate

C
Glucose 1,6-bisphosphate

D
fructose 6-phosphate
Question 7
1 / -0

Select the wrong statement.

A
When tripalmitin is used as a substance in respiration the R.Q.is 0.7

B
The intermediate compound which links glycolysis with Kreb's cycle is malic acid

C
One glucose molecules yields a net gain of 36 to 38 ATP molecules during aerobic respiration

D
One glucose molecules yields a net gain of 2 ATP molecules fermentation

E
The scheme of glycolysis was given by Embden,Meyerhof and Parnas

Solution

(1) Tripalmitin is a triglyceride of fatty acid palmitic acid so its RQ is 0.7.
(2) The intermediate compound which links glycolysis with the citric acid cycle is the two molecules of acetyl coenzyme A which is formed by the oxidation of the end product of glycolysis process called pyruvate release two molecules of carbon dioxide and two $$ NADH^+$$.
(3) In oxidative phosphorylation, glucose is broken down by three different processes or step. So in glycolysis (8 ATP), Kreb's Cycle (30 ATP).
(4) In fermentation, all ATP is consumed after glycolysis so no $$NADH^+$$ is formed and ETS is absent. Therefore only 2 ATP are produced.
(5) The credit of invention of detailed steps of glycolysis is given to Gustav Embden, Otto Meyerhof and J. Parnas in the 1940s.
So the wrong statement is 'The intermediate compound which links glycolysis with Kreb's cycle is malic acid'.
Question 8
1 / -0

Which one is a product of aerobic respiration?

A
Malic acid

B
Ethyl alcohol

C
Lactic acid

D
Phosphoglyceric acid
Solution
- Pyruvic acid is a product of Glycolysis, Malic acid is a product of aerobic respiration in the Kreb's cycle, and Ethyl alcohol/Lactic acid are the products of anaerobic respiration.
- Phosphoglyceric acid is the first stable product of photosynthesis in C$$_3$$ plants.
So, the correct answer is 'Malic acid'
Question 9
1 / -0

Which of the following is utilized first in respiration?

A
Fat

B
Protein

C
Sucrose

D
Hexose
Solution
- A respiratory substrate is an organic substance that is used up during respiration to liberate energy.
- Respiratory substrates include carbohydrates, proteins, fats, and organic acids.
- Hexose monosaccharide like glucose is the most common respiratory substrate.
- Out of the given options, hexose will be utilized first in respiration.
- Sucrose disaccharides are first converted into monosaccharides.
- Fats are first converted into sugars and proteins are converted into respiratory intermediates like acetyl CoA.
Thus, the correct answer is 'Hexose'.
Question 10
1 / -0

Which of the following forms the connecting link between glycolysis and Kreb's cycle?

A
Glucose

B
Ethyl alcohol

C
Lactic acid

D
Pyruvic acid

Solution

Pyruvic acid is produced as a final end product of glycolysis. This pyruvic acid then forms acetyl CoA. This acetyl CoA, acts as initial compound of Kreb's cycle.
So, the correct answer is 'Pyruvic acid'
