Question

Write an explanatory note on the
A. Glycolysis
B. Fermentation by yeast
C. Electron transport chain

Answer 1

Hint: The process of conversion of the glucose into the pyruvic acid is known as glycolysis.
2. The process of conversion of the glucose or lactose into lactic acid and alcohol is known as the process of fermentation.
3. Electron transport chain is defined as the metabolic process in which the electron passes from one carrier to the other which leads to the oxidation and release of energy.

Complete answer: The electron transport chain is defined as the metabolic process in which the electron passes from one carrier to the other which leads to the oxidation and release of energy.

Different cell handle the pyruvic acid release from the glycolysis in different ways some of them leads to the process of fermentation in the presence of yeast.
The process of fermentation completed in the anaerobic condition that is in the absence of oxygen in which pyruvic acid gets converted into lactic acid and alcohol.

The electron transport chain is the final step in the process of respiratory breakdown of the glucose to get the energy In the form of ATP. It released the energy that is stored in the form of $NADH^+$ and $FADH_2$ in the usable form that is in ATP.

Note: Oxygen is the most important element in the electron transport chain as it is the final hydrogen acceptor.
