Glycolysis

Aerobic cellular respiration is

the utilisation of oxygen by cells

for the production of ATP

It is a series of over 20 chemical

reactions that can be divided into

four phases

Glucose

2

ATP

2 Pyruvic

Acid

The first phase is called

Glycolysis and takes

Place in the cell

Cytoplasm

Glycolysis involves the breakdown

of one molecule of glucose (6C) to form

2 molecules of pyruvic acid (3C) or

Pyruvate; there is a net production

of two atp moleculesduring this phase

glycolysis1
GLYCOLYSIS

Glycolysis takes place in the 1 of cells and begins with the activation of the main respiratory substrate, namely the hexose sugar 2. This activation involves the addition of two 3 molecules provided by two molecules of 4. The resultant activated molecule is known as 5 and in the next stage of glycolysis it is split into two molecules of 6. The third stage entails the oxidation of these molecules by the removal of 7, which is transferred to a carrier called 8. The final stage is the production of the 3 carbon molecule 9 which also results in the formation of two molecules of 10.
