Document Summary

Atmospheric oxygen and the origin of eukaryotes. Covers up to end of today"s lecture. Answer: b. the word high makes it wrong. it should be low surface area for it to be true. Answer: answer is d) if its a) then it has to b). no prokaryotes have chloroplasts. they use a pigment (chlorophyll) for photosynthesis, but they do not have chloroplasts. The export of proteins created by ribosomes on the rough er. Most eukaryotes have mitochondria and all photosynthetic eukaryotes have chloroplasts. (note: prokaryotes do not have chloroplasts they have pigments called chlorophyll). Have their own dna (small, circular), ribosomes, mrna, and trna. They are capable of independent protein synthesis! Endosymbiotic theory for the origin of eukaryotes: engulfing of one prokaryote by another prokaryote is how life arose. (selection is favouring infolding of membrane) separate events). Step 2: mitochondria and chloroplasts from endosymbiotic events (in two. Proposes that they borrow products from one another leading to a.
