BI110 Lecture Notes - Lecture 8: Inner Membrane, Cellular Respiration, Cytoskeleton
Document Summary
Form in one compartment, fuse to another. Way proteins are secreted from a cell. Chemically modifies proteins made in rough er. Modifies proteins further before they reach their final destination. Golgi makes different vesicles- sends these to different locations as well. Large group of organelles able to carry out many functions. Proteins in er- stay in vesicles and transfer through golgi apparatus where they are released to outside of cell. Good way to bring in organic molecules ect. for energy. Vesicles transport materials throughout the endomembrane system. Also used for secretion to cell exterior, to bring molecules into the cell. Has their own dna- encoding genes that make proteins- important for cellular respiration. Inner membrane (folded,forms cristae (membrane folding back onto itself many times)) Inner membrane larger than the outer membrane - has more surface area. Mitochondria likely arose from process of endosymbiosis. Uses light energy to make organic molecules. Light energy being used to form co2.
