Brief introduction of Chapter 14 Respiration in Plants

All living organisms breathe but the question comes here why does the organism breathe? What happened to the air we breathe in?

The answer to the above questions lies in the fact that all living organisms need the energy to perform different metabolic activities of bodies and that energy comes through the oxidation of macromolecules which we called as food.

Only green plants present on earth can prepare their food rest others to depend on them so to obtain energy from the food we need to breathe. The process of oxidation of food to get energy is called respiration.

The site of aerobic respiration is Mitochondria. Respiration results in the breakdown of glucose which yield CO2 and Energy.

In this chapter, you will learn about processes involved in respiration such as glycolysis, Kreb cycle, Electron transport chain etc.

Glycolysis is the common step of respiration found in all living organisms which yield two molecules of pyruvic acid at the end.

During the process of respiration, various energy compounds such as NADPH, FADH2, GTP and ATP are formed.

In fermentation or lactic acid fermentation which are anaerobic processes yield very less energy as food undergoes partial oxidation.

In the aerobic process, there is complete oxidation of food which yield around 36 or 38 ATP molecules.

In this chapter, we will also get an overview of different types of various respiratory substrate and their efficiency.

At the end of the chapter, we will also learn about the respiratory quotient of the various substrate.
