This is a cellular respiration question, related to biology.
Some processes in our bodies require the use oxygen, others do not.
In this case, the conversion of pyruvic acid to acetyl co-enzyme A and the production of water in the electron transport chain do require oxygen.
If oxygen was not present for pyruvate, it would turn into lactic acid via fermentation. Water in the ETC is formed in the process when NADH and FADH2 are converted to molecular oxygen due to the electron transporters. The protons are then pumped and oxygen is reduced to form H2O.
Answer:
WHO is involved: (major protein players)
WHAT is being completed:
WHEN does it occur in the cycle of the cell:
WHERE does it occur in prokaryotes or eukaryotes:
WHY does replication happen:
Explanation:
These are the 5 W's for any situation in life but directly applied to biology and DNA these are the exact and specific W's
