AIIMS Botany Respiration In Plants Class 11 Questions

ATP formation occurs through which of the following-

How many pyruvate produced by oxidation of 1 glucose molecule?

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

Glycolysis is

Which is required in glycolysis?

Which is the correct link reaction?

Assertion: The behavior of honey bee to come out of the hive in large number is called swarming. Reason: It relieves the crowding and provides a means of founding new colonies.

Assertion : Fermentation occurs by incomplete oxidation of glucose. Reason : Yeast form ethanol & $\text{CO}_2$ from pyruvic acid.

Assertion : Most of the enzymes of oxidative decarboxylation are present in mitochondrial matrix. Reason : ETS operates on inner membrane of mitochondria

Oxyhaemoglobin dissociates into oxygen and deoxyhaemoglobin at

Aerobic respiration produces more usable chemical energy than fermentation, because fermentation involves

RQ (Respiratory Quotient) is defined as

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
