Document Summary
And arch: contain organelles, some possess cell walls and complex internal cytoskeleton (to keep everything where they should be) Some organelles: peroxisome, hydrogenosomes thought to be remnant of mito, something called amitochondriates those that don"t have mitochondria these cells have other ways of making atp, double mem. The nucleus: storage and expression of genes, double mem. structure, contains linear chromosomes of cell, non membrane bound nucleolus exists to make ribosomes, spatial separation transcription in and translation out, has nucleoporins. Rer: to make proteins, secretory pathway uses er/golgi also. Ser makes fatty acids and lipids for the mem. also makes modified proteins: transfer vesicles between er and golgi and secretory vesicles between golgi and mem. Mitochondria: power house of the cell, etc is present here to make atp, participates in later stages of cellular respiration, make gradient of h+ (chemiosmosis, mem. invaginations, tca cycle takes place here.
