BIOL 1090 Lecture Notes - Lecture 15: Cell Membrane, Nuclear Membrane, Mitochondrion
Document Summary
Human cold and influenza virus infects epithelial cells. Can not recreate itself needs a host to be active to create new particles. Over takes the cell and makes it explode (kills the cell: non-lytic or integrative: Viral dna, integrates its genome into the dna = provirus (dna of the virus) Not seen immediately, dominate for a certain period of time and then will be active after a certain time. Boundary (plasma membrane = outside of the cell, nuclear membrane = outside of nucleus) Trilaminar 2 layers, a the center portion. Amphipathic head is hydrophobic (phosphate group) and tail is hydrophilic (fatty acid-lipid chain) With glycoprotein floating in section of the membrane. Has two membranes outer and inner by-layer membrane: inner membrane contain high levels of protein which are involved in the electron transport chain. Integral part of the membrane on the lipid bilayer. Proteins that form a hole in the membrane (control the incoming and outgoing substances)
