Suppose that you found an unknown organism. You analyzed it and you found that it uses energy from light to convert CO2 into an organic form. Based on your findings, which of the following is this organism most likely?
Imagine that you are studying two basic cellular reactions: cellular respiration and photosynthesis. You have no other means to determine which one is going on but to isolate and identify two of the electron carriers involved: NAD+ and NADP+. How would these two carriers help you distinguish which cellular reaction is going on?
