Biochemistry 2288A Lecture Notes - Cytoplasmic Streaming, Golgi Apparatus, Protein Purification
Document Summary
Textbook pages topic introduction: central dogma, amino acids, protein structure, protein function, enzyme catalysis, protein purification. Cytoskeleton and cytoplasmic streaming prokaryotes > do not have a membrane-inclosed nucleus (instead nucleoid) No cytoskeleton or cytoplasmic streaming prokaryotes are the most diverse of cells. Organelles nucleus - information storage of the cell. > double-membraned (nuclear envelope) mitochondria - generates usable energy from food to power the cell. > harness energy from oxidation of sugars to produce atp (through cellular respiration) chloroplasts (plant cells only/ not fungi) > internal stacks of membranes containing green pigment chlorophyll. > site where most cell membrane components and materials for export from the cell are made golgi apparatus. > receives and chemically modifies molecules made in the er lysosomes. > releases nutrients from food particles; breaks down molecules for recycling or excretion peroxisomes. > vesicles that provide contained environment for hydrogen peroxide reactions cytosol is a concentrated aqueous gel of large and small molecules.
