Select the wrong statement -a)When tripalmitin is used as a substrate ...
Explanation:
The correct statement is option B: The intermediate compound which links glycolysis with the Krebs cycle is malic acid. This statement is incorrect because the intermediate compound that links glycolysis with the Krebs cycle is actually pyruvate, not malic acid.
Here is a detailed explanation of each statement:
a) When tripalmitin is used as a substrate in respiration, the RQ is 0.7:
- This statement is correct. The respiratory quotient (RQ) is the ratio of carbon dioxide produced to oxygen consumed during respiration. When tripalmitin, a triglyceride composed of three palmitic acid molecules, is used as a substrate, it undergoes beta-oxidation to produce acetyl-CoA molecules. The complete oxidation of one molecule of tripalmitin generates 51 molecules of acetyl-CoA. During the Krebs cycle, these acetyl-CoA molecules are oxidized to produce carbon dioxide. The total number of carbon dioxide molecules produced is 36. The oxygen consumed during respiration is 51 molecules. Therefore, the RQ is 36/51, which is approximately 0.7.
b) The intermediate compound which links glycolysis with the Krebs cycle is malic acid:
- This statement is incorrect. The intermediate compound that links glycolysis with the Krebs cycle is pyruvate. In glycolysis, glucose is broken down to produce two molecules of pyruvate. Pyruvate then enters the mitochondria, where it is converted into acetyl-CoA, which enters the Krebs cycle.
c) One glucose molecule yields a net gain of 36 ATP molecules during aerobic respiration:
- This statement is correct. During aerobic respiration, one molecule of glucose can produce a net gain of 36 ATP molecules. This includes 2 ATP molecules from glycolysis, 2 ATP molecules from the Krebs cycle, and 32 ATP molecules from oxidative phosphorylation in the electron transport chain.
d) One glucose molecule yields a net gain of 2 ATP molecules during glycolysis:
- This statement is correct. During glycolysis, one molecule of glucose is converted into two molecules of pyruvate. This process consumes 2 ATP molecules but also produces 4 ATP molecules, resulting in a net gain of 2 ATP molecules.
The correct statement is option B: The intermediate compound which links glycolysis with the Krebs cycle is malic acid. This statement is incorrect because the intermediate compound that links glycolysis with the Krebs cycle is actually pyruvate, not malic acid.
