BIO E121 Lecture Notes - Lecture 10: Tubulin, Microfilament, Exocytosis
Document Summary
Compare and contrast structural and function differences between the smooth endoplasmic reticulum and rough endoplasmic reticulum. Both help in the production and storage of proteins. Function: processes amino acid chains made by attached ribosomes. Structural: studded with ribosomes (on its surface) Function: detoxification (drugs/alcohol), makes lipids & steroid hormones. List the steps for phagocytic killing and removal of damaged organelles. Lysosomal enzymes break bacteria down into small molecules that diffuse into cytoplasm. Some indigestible substances leave the cell by exocytosis (releases out) Lysosomal enzymes break down organelles into smaller molecules that returns to cytoplasm for reuse. List what each is made of and their function. Function: responsible for structure and movement of cilia & flagella. Made of: diverse group of rope-like fibers. Function: maintain cell shape & anchor organelles. Function: form a band that pinches cell into two during cell division. Made of: nine sets of three microtubules arranged in a ring.
