Question
NAD+, it can live and reproduce in conditions of low atmospheric oxygen on Mars, but this process is slow because fermentation is not very efficient. Suddenly, a fungal population is found to be growing at a much faster rate because it has evolved to utilize an alternative acceptor at the end of the electron transport chain. Which of these elements would be the most likely candidate to act as an alternative electron acceptor in oxidative phosphorylation?
silicon (Si)
polonium (Po)
aluminum (Al)
rubidium (Rb)
None, only oxygen can be oxidized.
A-silicon (Si)
B-polonium (Po)
C-aluminum (Al)
D-rubidium (Rb)
E-None, only oxygen can be oxidized.
Explanation / Answer
Option E
None, only oxygen can be oxidized because it also helps creating hyrogen ion gradient across the membrane
