Document Summary
Molecules: assembly of atoms, major molecules are carbs, lipids, proteins, and nucleic acids. Cells: basic unit of life, use energy, metabolism, remove waste. Tissues: collection of similar cells with same local function. Homeostasis: maintain the normal physiological state. Negative feedback: common, event x causes a change away from a set point, response y causes a return to set point, basis of homeostasis, ex. Blood pressure, ion concentrations, muscle reflexes (parkinson"s disease: absence of neurotransmitter dopamine) Ribosomes: combinations of protein and rna, free ribosomes make proteins for use in cytosol, few or no modifications after production, chaperones help protein folding. Located in cytosol and er: protein must fold into lowest energy position functional. Protein modification: proteins in golgi apparatus have amino acids removed or modified, sugars added to proteins/modified, proteins only work in specific shapes, most proteins naturally fold into their appropriate shape, chaperones help proteins fold properly.
