Answer:
Glycolysis is the common pathway for both aerobic and anaerobic forms of respiration. The process by which the glucose (6C compound) is split into two molecules of pyruvic acid (3C compound) is called glycolysis or EMP pathway. It occurs in the cytoplasm.
Reactions involved in glycolysis are as follows:
(i) The glucose is phosphorylated with ATP to form glucose-6-phosphate. The reaction is catalyzed by the enzyme hexokinase.
(ii) Glucose-6-phosphate is isomerized to form fructose-6-phosphate by phosphoglucoisomerase.
(iii) Fructose-6-phosphate is then phosphorylated using ATP to form fructose 1,6-bisphosphate. This reaction is catalyzed by phosphofructokinase. The ATP is dephosphorylated to ADP.
(iv) Fructose 1, 6-bisphosphate is cleaved by the enzyme aldolase to two molecules of 3C compounds-dihydroxy acetone phosphate (DHAP) and 3-phosphoglyceraldehyde. These two trioses are isomers.
