What happens during the link reaction? what is added and what is lost: what is formed? how many times does it happen (5)

Decarboxylated = loses 1c to form co2 loses 2H+ to reduce NAD+ Coenzyme A CoA added to form acetyl CoA pyruvate (3c) = acetyl coA (2c) happens twice for each glucose (bec 2 pyruvates per glucose)
