What is the overall reaction for fermentation in yeast

Alcoholic fermentation occurs in yeast and produces ethanol and carbon dioxide. Fermentation only produces two ATP per glucose molecule through glycolysis, which is much less ATP than cellular respiration. Hope this helps.

is there multiple choice answers?

answer:

the answer is 6 valence electrons.

explanation:

valence is the # of electrons on the outer most shell of an atom.

oxygen has 6.

although, the valency of oxygen is 2, because it only needs to make 2 covalent bonds, or gain 2 electrons, to achieve the stable octet configuration of a noble gas.

that's it!

if you need further assistance, let me know: )
