Membrane Protein Functions {Ans: Transport, enzymes, signal transduction, cell to cell recognition, intercellular joining, attachment to the cytoskeleton}Nucleus {Ans: The organelle of a eukaryotic cell that contains the genetic material in the form of chromosomes, made up of chromatin}Intermediate Filaments {Ans: A component of the cytoskeleton that includes filaments intermediate in size between microtubules and microfilaments; Reinforce cell shape, fix organelle position}Turgid {Ans: Swollen or distended, as in plant cells (A walled cell becomes this if it has a lower water potential than its surroundings, resulting in entry of water)}Electrogenic or H+ Pumps {Ans: AKA Proton pumps; active; Carrier-mediated transport; Create voltages across membranes for other cell processes; Used by plants, fungi, and bacteria}rRNA {Ans: RNA molecules that, together with proteins, make up ribosomes; the most abundant type of RNA}
