Hey everyone I am pushpanjali sagar 2nd year mbbs Student in this lacture i will be discussing about glycolysis which means breakdown of glucose into two molecules of pyruvic acid .which occurs in cytoplasm of the cell . It involves 10 reactions 1st 3rd and 10th reaction are irreversible rest all are reversible . In the 1st step of glycolysis glucose is converted into glucose 6 phosphate by the help of enzyme hexokinase using the one ATP.

One the second step glucose 6phophate breaks into fructose 6phosphate by the enzyme isomerase and than fructose 6 phosphate breakes into fructose 1,6 bis phospate by the enzyme pgosphofructokinase and breaks into phosphoglyceraldehyde and dihydrocyacetonephosphate by the enxyme aldolase than phosphoglyceraldehyde breaks into 1,6phosphoglyceric acid than 1,6 phosphogkyceric acid breaks into 3 phosphoglyceric acid tha this breaks into 3 phosphoglyceric acid by the presence of enzyme mutase than this 3 phosphoglyceric acid breaks into 2 phosphoglyceric glyceric acid than this 2phosphoglyceric acid breaks into2 phosphoenol pyruvate by the enzyme enolase than this will breaks into 2 molecules of pyruvic acid .

In this entire process there is formation of 8 atp
