AIIMS Botany Respiration In Plants Class 11 Questions

ATP formation occurs through which of the following-

Assertion: Respiratory pathway is considered as an amphibolic pathway Reason: It involves both anabolism and catabolism.

Glycolysis is

The statement given in the assertion that, ‘fermentation is an incomplete oxidation of glucose’ is correct. The statement given in the reason provides the correct explanation for this that fermentation is catalyzed by the enzymes known as pyruvic acid decarboxylase and alcoholic dehydrogenase.

Oxyhaemoglobin dissociates into oxygen and deoxyhaemoglobin at

In aerobic respiration, total number of ATP molecules formed from 1 glucose molecule is

Assertion: Extra oxygen consumption in human body is known as oxygen debt. Reason: The extra oxygen is required by the body to oxidise the accumulated lactic acid produced during strenuous exercise.

After glycolysis, fate of glucose in mitochondrial matrix is

The enzyme decarboxylase catalyses the following step

Which of the following is true regarding the given electron transport chain? CoQ → Cyt c → Cyt aa₃ → O₂ (a) CoQ → Cyt c is H⁺ absorbing site (b) aa₃ → O₂ H⁺ yielding site (c) CoQ → Cyt c is H⁺ yielding site and aa₃ → O₂ is H⁺ absorbing site (d) no H⁺ is absorbed or released

Assertion: Glycolysis is the first step of respiration in which glucose completely breaks into CO₂ and H₂O. Reason: In this process, there is net gain of twenty four molecules of ATP.

Which of the following is the connecting link between glycolysis and Krebs cycle?

Glycolysis is found in cytoplasm of virtually all types of aerobic/anaerobic cells. In this process, glucose is converted into a compound which is

In respiration from 180g of glucose which of the following is formed
