The final electron acceptor during ETS in respiration is
Open in App
Solution
The correct option is A Oxygen.
The final stage of cellular respiration is the electron transport chain (ETS). The ETS is a series of molecules embedded in the mitochondrial membrane. The first molecule accepts protons and electrons from the products of the Krebs cycle. The electrons are passed from molecule to molecule and finally react with oxygen and protons to form water. Without oxygen the final reaction cannot occur. In the absence of oxygen the ETS stops working and no ATP is generated.
