Ch. 9: Cellular Respiration!!
Glycolysis
citric
acid
cycle
Oxidative Phosphorylation
So, what's it for?
Energy!!!
Most organisms use Catabolic pathways to harvest energy.
And do fun stuff!!!
There are basically 2 types of catabolic processes... aerobic respiration:
& Anaerobic Respiration.
And Fermentation, but we'll get to that later.
Cellular Respiration
- Glycolysis, Citric Acid Cycle, and OxPhoz. These 3 processes come together to form Cellular Respiration, and create anywhere from 36 to 38 ATP.
Now, let's get into some VIDEOSSS!!!
Glycolysis
Citric Acid Cycle (Krebs)
Oxidative Phosphorylation (coupled with Chemiosmosis)
This is in the presence of Oxygen. But what if there is no Oxygen? What if you're running, and you can't get to Oxygen? Or you're yeast, and need to do...yeast things, but can't use Oxygen?
Well, that's is what fermentation is for. Fermentation breaks down sugars, and uses that process to create ATP (energy). And depending on if you're human or yeasty, you use different types of it.
And for the more, alive variety, there's lactic acid. That's what we use!
Now
for a
closer
look
......
Lactic Acid Fermentation
as Glycolysis occurs...
And that's really it. Now for some questions!
