Chemiosmosis Flashcards
1
Q
What is the first step in chemiosmosis?
A
H+ move down the electrochemical gradient into the matrix via ATPsynthase
2
Q
What is the second step of chemiosmosis?
A
ATP is formed from the movement of H+
3
Q
What is the final step in chemiosmosis?
A
H+, e- and oxygen form water
4
Q
Why is oxygen important in chemiosmosis?
A
It is the final electron acceptor
5
Q
An inhibitor affects the final electron carrier in the ETC, why is this a problem?
A
Transfer of e- down the ETC stops so no energy produced to form ATP
Cellular respiration stops
6
Q
What is chemiosmosis?
A
Movement of H+ ions across a membrane which forms ATP
