Question: What are respiratory substrates? Name the most common respiratory substrate.
Answer: The compounds that are oxidized during the process of aerobic and anaerobic respiration are referred to as respiratory substrates.
Glucose, fats, proteins and organic acids form respiratory substrates, but Glucose forms the most common respiratory substrate.

Question: What are the main steps in aerobic respiration? Where does it take place?
Answer
: The main steps in Aerobic respiration are:

  • Glycolysis.
  • Oxidative decarboxylation of Pyruvate to acetyl coA.
  • Kreb’s cycle.
  • Electron transport chain.
  • Oxidative phosphorylation.
  • Glycolysis takes place in the cytoplasm.
  • Oxidative decarboxylation of pyruvate and Kreb’s cycle occur in the mitochondrial matrix.
  • Electron transport chain and oxidative phosphorylation occurs in the inner mitochondrial membrane.

Class 11 Biology Chapter 14 – Respiration In Plants – Chapter Summary

Do plants breathe? What is the purpose of respiration? We know that energy is needed for us to carry out day-to-day activities. Similarly, do plants also need energy? If yes, then how do they derive energy from their food? All these questions may seem random and unrelated questions, but all these topics are connected to the process of ‘Respiration’.

The plants need to respire; however, unlike animals, they do not have specialised organs. They have stoma and lenticels for this purpose. 

The energy required for ‘life’ processes is obtained by oxidation of some macromolecules that we call ‘food’. Plants prepare their own food through the process of photosynthesis. However, only the tissues with chloroplasts can prepare food, and this food will then be transported to different parts of the plant. Thereafter, the food is eventually converted into energy for growth and to carry out other life processes. 

In this chapter, we will learn about how respiration takes place and helps plants generate energy. This process is called cellular respiration. It is the mechanism of the breakdown of food materials within the cell to release energy and trapping this energy to synthesise ATP. Thus, to study cellular respiration, we will study various chemical cycles occurring in the plant. 

FAQs On Class 11 Biology Chapter 14 NCERT Solutions

Q.1: What exercises are discussed in Class 11 Biology Chapter 14?
Ans: List of all the exercises from Class 11 Biology Chapter 14 Respiration In Plants is given below:
Ex. 14.1: Do Plants Breathe?
Ex. 14.2: Glycolysis
Ex. 14.3: Fermentation
Ex. 14.4: Aerobic Respiration
Ex. 14.4.1: Tricarboxylic Acid Cycle
Ex. 14.4.2: Electron Transport System (ETS) and Oxidative Phosphorylation
Ex. 14.5: The Respiratory Balance Sheet
Ex. 14.6: Amphibolic Pathway
Ex. 14.7: Respiratory Quotient

Q.2: Where can I download NCERT Solutions for Class 11 Biology Chapter 14?
Ans: On this Embibe Page, candidates can download the PDF of NCERT Solutions for Class 11 Biology Chapter 14.

Q.3: Do plants breathe?
Ans: Plants require O2 for respiration through stomata and lenticels. During respiration, the complete combustion of glucose, which produces CO2 and H2O as end products, yields energy, most of which is released out as heat.

Q.4: What is the respiratory balance sheet?
Ans: The balance sheet of respiration gives a theoretical value about the net gain of ATP per glucose molecule. The complete process produces 38 ATP from 1 mole of glucose.

Q.5: What do you mean by respiratory quotient Class 11?
Ans: The respiratory quotient ratio is the volume of carbon dioxide expelled to the volume of oxygen used during cellular respiration. Respiratory quotient, RQ = Volume of CO2 expelled/Volume of O2 consumed.
