Physiology 2130 Lecture Notes - The Fluid, Pinocytosis, Microtubule
Document Summary
Storage vesicles lysosomes; contents stored within cell, act as digestive system for cell: contain enzymes to destroy damaged organelles, kill bacteria, free ribosomes dense granules of rna and protein, manufacture proteins from amino and break down other kinds of biomolecules acids, 2 types: fixed ribosomes attached to er and free ribosomes which float in cytoplasm, usually form in groups of 20 known as polyribosomes, mitochondrion organelle where most atp is generated giving it the name of the powerhouse of the cell, number depends on the energy the cell needs and they can replicate themselves, endoplasmic reticulum continuation of nuclear membrane, used to house synthesis, storage and transport proteins, rough er covered in ribosomes, smooth er lacks ribosomes, proteins made in er are transported by vesicles to the golgi, centriole cylindrical bundles of microtubules that direct dna strands through cell division.
