Respiration in Plants Assertion and Reason Questions for NEET
In each of the following questions, a statement of Assertion (A) is given and a corresponding statement of Reason (R) is given just below it. Of the statements, pick the correct answer as :
Assertion : Yeast produces ethyl alcohol during anaerobic respiration. Reason : Accumulation of alcohol, produced by fermentation, beyond a certain limit can kill the microorganism.
Assertion : About 50% of the energy liberated during cellular respiration is used for synthesis of biomolecules and other life activities. Reason : Energy is liberated in controlled fashion in several steps and is mostly stored in ATP
Assertion : An intermediate RQ value is obtained where an organism is undergoing both aerobic and anaerobic respiration. Reason : RQ values indicate that living organisms always use a single respiratory substrate.
Assertion : 3-phosphoglycerate is changed to 2-phosphoglycerate by isomerisation during glycolysis. Reason : Isomerisation of 3-phosphoglycerate is an energy spending phase of glycolysis.
Assertion : An electron gradient formed on the inner mitochondrial membrane forms ATP. Reason : F1 particles are present in the inner mitochondrial membrane.
Assertion : The passage of electrons in electron transport chain is a downhill journey. Reason : Electron passes from one enzyme to the next with a loss of energy at each step.
Assertion : Substrate level phosphorylation is not present in Krebs' cycle. Reason : Substrate level phosphorylation involves direct synthesis of ATP from metabolites.
Assertion : Oxidative phosphorylation is linked to terminal oxidation of reduced coenzymes NADH and FADH2 in respiration. Reason : The coenzymes release electrons that pass over a series of carriers in electron transport chain
Assertion : Fats are used as respiratory substrates by a number of organisms. Reason : Fats contain more energy as compared to carbohydrates.
Assertion : Glycolysis uses oxygen as terminal oxidant. Reason : Glycolysis involves partial oxidation of glucose to pyruvic acid.
Respiration in Plants Figure-Based Questions for NEET
Study the given figure and answer the following questions.
(a) Identify A, B and C in the given figure.
A. The given figure is showing ATP synthesis by F0 – F1 particle. Here, A is 2H+, B is F0 and C is F1.
(b) How does a proton gradient develop in the system?
A. F0 – F1 particles are present in the inner mitochondrial membrane. ATP synthase becomes active when there is a proton gradient having higher concentration of H+ on the F0 side as compared to F1 side. Increased proton concentration in outer surface of inner mitochondrial membrane is produced by the pushing of protons with the help of energy liberated by passage of electrons from one carrier to another during electron transport chain.
(c) At which condition will C produce ATP?
A. The flow of protons through the F0 channel induces F1 particle to function as ATP synthase. The energy of the proton gradient is used in attaching a phosphate radicle to ADP by high energy bond and this helps in producing ATP.
