Errata

Oops: here are TWO mistakes that I found in earlier postings.

1. On Fermentation (10/25):
I wrote "… pyruvate oxidizes NAD+ to NADH, and is converted (reduced) to lactate ..."
In fact, pyruvate oxidizes NADH to NAD+.

2. In the Krebs cycle cartoon (10/28), ATP and ADP should respectively read GTP and GDP.

I've fixed these now, but I wanted to make sure nobody was misled.
cheers,
