Which of the following processes do NOT require oxygen?
1) glycolysis
2) cellular respiration
3) ATP production in the mitochondria
4) CO2 production
What happens to cells that use up their available oxygen?
they will no longer be able to perform anaerobic respiration.
high levels of fermentation products will build up.
they will no longer be able to produce adequate amounts of ATP.
they will no longer be able to absorb water and will become dehydrated.
Acetyl CoA will accumulate
How do fermentation and anaerobic respiration enable cells to produce ATP without the use of oxygen?
