Cards

Term
The process of creating ADP to ATP in the ETC
Definition
Oxidative phosphorylation
Term
Powerhouse of the cell
Definition
Mitochondria
Term
What happens if there is no aoxygen to recieve electrons at the end?
Definition
Without oxygen mitochondrial metabolism is blocked which means that no ATP can be created
