Daily Challenge: Last week, you were asked to look at the evolution of metabolism. We're going to continue this today. Now having looked at plant based photosynthesis, and variations on plant based photosynthesis, discuss the evolution of photosynthesis an metabolism. Which would have come first? How would early organisms gain the required reducing potential? How would early organisms gain biologically available carbon? What is the importance of Rubisco? What is the importance of having a photosystem that can use water to regenerate needed electrons (and give off oxygen)?
Consider these questions, and then write up your impressions.
