I have a question about oxygen and the body....?

Post by RediscoveringBio » Fri Jun 09, 2006 4:24 pm

I wanted to know the events that occur if oxygen is deprived from a cell. Why will we die if we dont get oxygen to your cells?

How will ETS and chemiosmotic phosphorulation, the Krebs cycle, the conversion of pyruvate to acetyl coA and glycolysis be effected?

I've looked it up, but i just dont get it. If anyone can help, at all, that would be awesome... thanks :roll:

Without oxygen= less ATP
Glycolysis does not need O2. the other steps need it.
For more info feel free to make a search...

This might sound like a stupid question but wouldn't you just be weaker without oxygen?
This forum is so cool

just weaker? How? How will you get the ATP you need? Glycolysis is not enough.

Yup, getting weaker....less ATP = insufficient energy for skeletal and visceral muscles...so? is it the definition of 'weak'?? :mrgreen:

I think your cells would be deproived of whatever it needs and would just crinkle up and die, then you'd die. :D

As previous people have said. Your body needs more ATP than glycolysis (which works without) can provide. If you don't get oxygen, your cells don't work and die. No oxygen in brain means u can brain damage and die pretty quickly.
