Sal, like an idiot, I went to other videos first. Between their potato cameras, the lack of ANY charisma, and my general disinterest, I was ready to just throw in the towel and realize I couldn't care less about plant metabolism if it were telecast on CSPAN. Then I remembered my academic blankey, KA. Thanks, KA for reviving me and sheltering me under your safe, warm wings.

Isn't this just a way for plant to guarantee to get CO2, even when it doesn't get it from air outside. Or where does those CO2 molecyls go?

NADPH, ATP and NH3 are also uselessly wasted in photorespiration

Looks like photorespiration only happens in significant amounts when the stomata are closed. If they are closed, then the 3 carbon dioxide atoms lost to this process don't have anywhere else to go. So they will probably be reabsorbed in the normal Calvin-Benson cycle.

I noticed that Sal wrote Rubisco's name as RuBP oxygenase-carboxylase. However, I learned in one of his previous videos that Rubisco is short for RuBP carboxylase-oxygenase (hence the acronym). Pointing out that detail, great video otherwise!
