Q

What is Glycolysis

A

A universal pathway that splits glucose into two 3 carbon molecules named Pyruvate.
. It requires 10 steps in the cytoplasm non of which require O2

Q

Describe the first 5 steps of Glycolisis

A

GLUCOSE ACTIVATION

ATP is used to activate glucose redistributing energy in the molecule and splitting it in half.

Q

The last 5 steps of Glycolysis

A

ENERGY EXTRACTION

Stores some energy in 2 molecules of electron carrier, NADH.
Other steps extract more of the energy, regaining the two ATP molecules invested earlier plus producing two more.
