Respiration In Plants Topic Based

Question : 1

RQ for glucose is


Answer: (b)

Question : 2

Excess of ATP inhibits the enzyme -


Answer: (b)

Question : 3

Which of the following is correct about cytochrome?


Answer: (d)

Question : 4

Which of the metabolites is common to respiration mediated breakdown of fats, carbohydrates and proteins ?


Answer: (d)

Question : 5

When oxygen is not available to a muscle cell, NADH formed during glycolysis does not pass electrons to the ETS. Instead, it passes hydrogen atoms to


Answer: (a)

In human muscle cell lactic acid fermentation occurs where pyruvic acid produced in glycolysis is reduced by NADH2 to form lactic acid without producing carbon dioxide. In fermentation process less energy is released.

${CH_{3}COCOOH} ↙ {\text"Pyruvic acid"} + NADH_{2} → ↖ {\text"Lactate dehydrogenase"} ↙ {\text"FMN, Zn^{2+}"} {CH_{3}CHOHCOOH} ↙ {\text"Lactic acid"} + NAD$

Question : 6

Aerobic respiratory pathway is appropriately termed


Answer: (b)

Question : 7

In glycolysis, during oxidation electrons are removed by–


Answer: (d)

Question : 8

During which stage in the complete oxidation of glucose are the highest number of energy deriving molecules (ATP)formed from ADP –


Answer: (c)

Question : 9

Assertion:
Respiratory pathway now a day called as amphibolic pathway.
Reason:
Respiratory pathway is involved in both catabolism and anabolism.


Answer: (b)

Question : 10

The total ATP production during EMP pathway is


Answer: (a)

Question : 11

The formation of acetyl coenzyme–A from pyruvic acid is the result of its


Answer: (d)

Question : 12

When protein molecules are used as fuel for aerobic cellular respiration, _____ are produced as waste.


Answer: (b)

Prior to their entry into the reactions of cellular respiration, the amino group is removed from amino acids.

Question : 13

Net gain of ATP molecules, during aerobic respiration, is


Answer: (a)

Question : 14

The energy-releasing metabolic process in which substrate is oxidised without an external electron acceptor is called


Answer: (c)

Fermentation is the process of deriving energy from the oxidation of organic compounds such as carbohydrates and using an endogenous electron acceptor not external or exogenous, which is usually an organic compound, as opposed to respiration where electrons are donated to an exogenous electron acceptor, such as oxygen via an electron transport chain.

Question : 15

EMP can produce a total of


Answer: (c)

Question : 16

Which of the following is essential for conversion of pyruvic acid into acetyl Co-A?


Answer: (d)

Question : 17

R.Q. is


Answer: (a)

Question : 18

Inside an active mitochondrion, most electrons follow which pathway?


Answer: (d)

Question : 19
