The link reaction phase uses a coenzyme A protein that links to the pyruvic acid to break
it down because the third phase can only accept a 2 carbon compound (pyruvic acid has 3
carbons each). The pyruvic acid is broken down into acetyl CoA (which has 2 carbons)
and also releases 2 electrons and 2 hydrogen ions. The electrons and hydrogen ions are
accepted by the NAD to form NADH which will be used in the last stage (ETC). Does
this phase (the link phase) produce any ATPS?
