Q

When alcohol reaches the liver where it needs to be metabolised, it typically enters one of 3 pathways, but all eventually lead to the formation of Acetaldehyde. Which one of the following is NOT one of these 3 pathways?

A

1 - formaldehyde

23
Q

Once ethanol has been metabolised and turned into Acetaldehyde by the enzyme alcohol dehydrogenase (ADH). ADH then used NAD+ to oxidise the acetaldehyde, which can lead to lots of NADH and few NAD+. What 2 things does this lead to?
