NCERT Solutions for Class 11 Biology Chapter 14 - Respiration in Plants


NCERT Solutions for Class 11 Biology Chapter 14 – Respiration in Plants: You may have wondered that from where does all this energy come from? We know we eat food for energy – but how is this energy taken from food? How is this energy utilized? Do all foods give the same amount of energy? Do plants ‘eat’? Where do plants get their energy from? And micro-organisms – for their energy requirements, do they eat ‘food’? Chapter 14 – Respiration in Plants of NCERT Class 11 Biology will tell you that all the energy required for ‘life’ processes is obtained by oxidation of some macromolecules that we call ‘food’. Only green plants and cyanobacteria can prepare their own food; by the process of photosynthesis, they trap light energy and convert it into chemical energy that is stored in the bonds of carbohydrates like glucose, sucrose, and starch. We must remember that in green plants too, not all cells, tissues and organs photosynthesize; only cells containing chloroplasts, that are most often located in the superficial layers, carry out photosynthesis. As the figure of the Citric acid cycle is given below.

Here are the important topics of Class 11 Biology Chapter 14 – Respiration in Plants mentioned below:

14.1 Do Plants Breathe?

14.2 Glycolysis

14.3 Fermentation

14.4 Aerobic Respiration

    14.4.1 Tricarboxylic Acid Cycle

    14.4.2 Electron Transport System (ETS) and Oxidative Phosphorylation

14.5 The Respiratory Balance Sheet

14.6 Amphibolic Pathway

14.7 Respiratory Quotient

NCERT Class 11 of Biology Chapter 14 – Respiration in Plants will also tell you about the pathway of respiration in plants. The respiratory pathway is an amphibolic pathway as it involves both anabolism and catabolism. The respiratory quotient depends upon the type of respiratory substance used during respiration.

After going through Chapter 14 – Respiration in Plants of NCERT, you must be able to answer a few questions which are mentioned below:

Q. Can you then calculate how many ATP molecules are directly synthesized in this pathway from one glucose molecule?

Q. What then would be the maximum concentration of alcohol in beverages that are naturally fermented?

If you are unable to answer these questions by yourself then you need to understand the chapter by reading it line by line. NCERT Solutions for Class 11 Biology Chapter 14 – Respiration in Plants will help you out in answering the questions which are mentioned in the NCERT book. As Solutions for NCERT Class 11 Biology will also help you in the preparation of other competitive exams like NEET and AIIMS along will your school exams.
