What occurs in all cells and can take place either with or without oxygen present

Glycolysis occurs in all cells and can take place either with or without oxygen present.

Glycolysis occurs in the cytosol of the cell and it is the process where glucose is broken down by enzymes thus releasing energy and pyruvic acid.

This process requires an electron carrier molecule called NAD+ which absorbs an electron.

the cells uses some of the atoms of the glucose molecules to atp molecules. the atoms of the glucose molecules will then be converted into energy which will be eventually stored in atp. the energy produced which are stored in atp are coming from the glucose’s chemical bonds.
