$\large{\red{\underline{\tt{Answer}}}}$

• The breakdown of glucose molecule into 2 pyruvic acid molecule is called Glycolysis.

• It occurs in cytoplasm of cell.

• This is common in aerobic and as well as anaerobic respiration.

Answer 2

Glycolysis is the central pathway for the glucose catabolism in which glucose (6-carbon compound) is converted into pyruvate (3-carbon compound) through a sequence of 10 steps.

• Glycolysis takes place in both aerobic and anaerobic organisms and is the first step towards the metabolism of glucose.
• The glycolytic sequence of reactions differs from one species to the other in the mechanism of its regulation and the subsequent metabolic fate of the pyruvate formed at the end of the process.
• In aerobic organisms, glycolysis is the prelude to the citric acid cycle and the electron transport chain, which together release most of the energy contained in glucose.
• It is also referred to as Embden-Meyerhof-Parnas or EMP pathway, in honor of the pioneer workers in the field.

A summary of the process of glycolysis cab be written as follows:

C6H12O6 + 2ADP + 2Pi + 2NAD+ → 2C3H4O3 + 2H2O + 2ATP + 2NADH + 2H+

In words, the equation is written as:

Glucose + Adenosine diphosphate + Phosphate + Nicotinamide adenine dinucleotide

↓

Pyruvate + Water + Adenosine triphosphate + Nicotinamide adenine dinucleotide + Hydrogen ions
