A Correct answer
Explanation

RNTCP stands for Revised National TB Control Programme. WHO has recommended Directly Observed Treatment Short course (DOTS) strategy to control TB. Patients are given anti TB drugs under direct observation of healthcare providers. Systemic care is taken till the patient is fully cured. This treatment goes up to $6$ months.

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

  1. Glucose

  2. Ethyl alcohol

  3. Lactic acid

  4. Pyruvic acid
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation
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'

B Correct answer
Explanation

Sir Hans Adolf Krebs was a German born British physician and biochemist. He was the pioneer scientist in study of cellular respiration, a biochemical pathway in cells for production of energy.

Out of 38 molecules of ATP produced after aerobic respiration of glucose, the break up in ATP production in glycolysis (P). pyruvic acid to acetyl CoA formation (Q) and Krebs cycle (R) is 

  1. P = 2, Q = 6, R = 30

  2. P = 8, Q = 6, R = 24

  3. P = 8, Q = 10, R = 20

  4. P = 2, Q = 12, R = 24
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Glycolysis produces 8 ATP (2 net ATP + 2 NADH yielding 6 ATP via shuttle), link reaction produces 6 ATP (2 NADH), and the Krebs cycle produces 24 ATP (6 NADH, 2 FADH2, 2 GTP/ATP). The total is 38 ATP.

Aerobic respiratory pathway is appropriate termed ___________.

  1. Anabolic

  2. Catabolic

  3. Amphibolic

  4. Parabolic
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Respiration is called amphibolic because it involves both catabolic processes (breakdown of substrates to release energy) and anabolic processes (use of respiratory intermediates for biosynthesis).

Which of the two statements together support that respiratory pathway is an amphibolic pathway.
i) Fats breakdown to glycerol and fatty acids, subsequently yields acetyl CoA
ii) In respiration C-C bonds of complex compounds breakdown through oxidation leading to release of energy
iii) Acetyl CoA from respiratory pathway is withdrawn for synthesis of fatty acids
iv) Proteins are degraded by protease to amino acids and enter the respiratory pathway

  1. i, ii

  2. i, iv

  3. ii, iv

  4. ii, iii
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Statement ii describes the catabolic nature (breakdown of C-C bonds), while statement iii describes the anabolic nature (withdrawal of intermediates like Acetyl CoA for fatty acid synthesis), together defining the amphibolic pathway.

Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

During the process of glycolysis 8 ATP molecules are produced in aerobic respiration. In the case of Krebs cycle 30 ATP molecules can be produced.
