E)Krebs cycle/ cristae of mitochondria
Krebs cycle occurs inside the matrix of the mitochondria. Electron transport chain takes place in the cristae.
They might be deep inside
Answer:
No more reactions occurs.
Explanation:
The activity of other metabolic pathways also change in response to the proton which enters mitochondria without passing through ATP synthase because ATP synthase is responsible for the production of ATP molecules from proton. If this ATP is not produced no further reactions occurs in the cell. This ATP is used by the cells in various activities so if the proton does not pass through ATP synthase then no energy in the form of ATP is present for other metabolic pathways of the cells.
Quick reactions/reflexes which do not need to be process by the brain in order to determine a response.
