Document Summary
Cell biology lecture- topic 5: slide 5. Mitochondria do more than just produce atp, are involve in many metabolic processes. Mitochondria play a role in mitigation of cellular stress. Calcium is important ion in cells, regulated by mitochondria. Chloroplasts are associated with photosynthesis but do they accomplish more? (answer for yourselves, from readings: slide 6. Mitochondria structure has certain unique feature like double membrane. Looking at mitochondria, there is a purpose for the cristae Answer: surface area, because there is more area for etc to occur, produce more. The etc itself is a protein that builds a hydrogen gradient. The blue structure is atpase at the end. We want to move the bottom part, which phosphorylizes adp to atp. Every time the h goes through, you can move a portion of b. Part of it is embedded in the inner mitochondrila matrix. Proton gradient is built between the two membranes.
