MICB 201 Lecture Notes - Lecture 19: Mahoney Lake, Atp Synthase, Oxidative Phosphorylation
Document Summary
Chapter 10: the autotrophic way of life (continued) Thylakoids membrane sacs derived from, but not continuous with, the cytoplasmic membrane: thylakoid membrane: functional equivalent of the cytoplasmic membrane, thylakoid lumen: functional equivalent of the periplasm. Psii, etc, psi and atp synthase are embedded in the thylakoid membrane. thousands of copies of each ps and atp synthase. H+ are pumped out from the lumen to the cytoplasm. Photosynthetic etc: thylakoid membranes: unlike eukaryotic cells eukaryotic cells that perform both oxidative phosphorylation and photophosphorylation use different organellar compartments, glucose-c stored in chloroplasts is respired in mitochondria.

Photosynthesis: use of light energy to synthesize the atp and nadph needed to reduce co2-c. Chemosynthesis: use of energy produced by reacting inorganic chemical nutrients to synthesize the. Ecologically important for at least 2 reasons: photosynthesis primary production.
