Document Summary
Fun fact: on cold days your nose drips because cilia are paralyzed by the cold; letting the mucus run down instead of up like it is supposed to: flagella. Example: sperm (only human cell with a flagella) Ribosome: made of ribosomal rna (rrna) and protein, two types. Fixed (bound to rough endoplasmic reticulum: function. Protein synthesis (they are the workbench of the cell) Mitochondria (plural) / mitochondrion (singular: surrounded by two membranes. Inner folds of the inner membrane are called cristae. Cristae increase surface area and contain enzymes to make atp: site of atp synthesis, powerhouse , cellular respiration. Glucose + oxygen (o2) carbon dioxide (co2) + water (h2o) + energy. Endoplasmic reticulum (er: the er is a network of hollow membrane bound tubes and sacs. Proteins are synthesized by the ribosomes and injected into the hollow interior of the rough endoplasmic reticulum.
