Question

Select the wrong statement(s) about respiration.
a) It consists of breathing, oxidation of food and energy storage in the form of ATP.
b) Cytoplasm and mitochondria are necessary for the completion of aerobic respiration.
c) Complete oxidation of food into ethanol or lactic acids, $C{O}_2$ and few molecules of ATP are seen in anaerobic respiration.
d) In the older portions of woody plants, the gaseous exchange takes place through stomatal apertures.
Statements that are entirely wrong are

• A. a) and b)
• B. b) and c)
• C. a) and d)
• D. c) and d)

Answer 1

Answer: (D)

c) and d)

Anaerobic respiration takes place in the absence of oxygen. So, oxidation of food does not take place. So, statement c is wrong. Gaseous exchange occurs through leaves that have minute tiny apertures over them called stomata.

Statement a and b are true. We know that respiration consists of breathing, which includes inhalation and exhalation, oxidation of food and also it stores energy the form of ATP. The cytoplasm is the jelly-like fluid matrix that contains different cell organelles like mitochondria. All the steps of cellular respiration occur inside mitochondria.

So, statement (c) and (d) are wrong statements and option D is the correct answer.
