Place the three stages of aerobic cellular respiration in the correct order from 1 to 3.

1. GLYCOLYSIS

2. KREBS CYCLE

3. ELECTRON TRANSPORT CHAIN

The correct answer is- 1) Glycolysis, 2) Kreb cycle, 3) Electron transport chain.

Cellular respiration is a process of oxidation of food molecule ( like glucose) so as to form carbon dioxide, water, and large amount of energy in the form of ATP ( adenosine triphosphate). It can be of two types that is aerobic ( that occurs in eukaryotes) and anaerobic ( in prokaryotes) cellular respiration.

The three phases of aerobic cellular respiration ( occurs in the presence of oxygen) are -

1) Glycolysis ( takes place in cytoplasm)- Glucose is broken down into 2 molecules of pyruvate with the release of net 2 ATP, 2NADH.

2) Kreb cycle ( takes place in mitochondrial matrix)- More energy is driven when pyruvate is first conveted into acetyle CoA ( acetyl coenzyme  A) that is further oxidised to release 1ATP, 3NADH, and FADH2.

3) Electron transport chain ( in the inner mitochondrial membrane)- It is the final stage of aerobic respiration in which maximum amount ( upto 36 ATP) of energy is harvested.

liquid crystals are matters in a state which have properties between those of conventional liquids and those of solid crystals[1]. liquid crystal is partially ordered and anisotropic. in terms of molecular order, liquid crystal molecules have one-dimensional or two-dimensional long - range order.
