Question

What is Glycolysis? Write main steps involved.

Answer 1

Glycolysis - It is a stepwise series of various interactions, which results in breakdown of one molecule of glucose, to 2 molecules of Pyruvic acid.
$\begin{array}{cc}{C}_6{H}_{12}{O}_6& +2NAD\\ Glucose& HydrogenAcceptor\end{array}\to \begin{array}{cc}2C{H}_{3}CO.COOH& +2NAD{H}_2\\ PyruvicAcid& ReducingHydrogenAcceptor\end{array}$
Main steps of Glycolysis -
(i) This process takes place in the absence of oxygen and does not remove CO${}_2$
(ii) From one molecule of glucose, 2 molecules of Pyruvic acid are formed.
(iii) Glycolysis is an oxidation process which involves oxidation of each glucose molecule, and 2 ATP molecules are formed.
(iv) Chemical energy are stored in the molecules of ATP and NADH${}_2$.
(v) Stepwise reaction of respiration is performed in the cellular matter. It does not requires O${}_2$.
