BIOL 1000 Lecture Notes - Lecture 11: Endomembrane System, Nuclear Membrane, Nuclear Dna
Document Summary
Synthesizes lipids that become part of cell membrane. -special hydrolytic enzymes: involved in breaking down to original monomers. - no longer required by cell to monomers. -takes in food particles by phagocytosis in amoeba eating. - type of wbc, engulfs invaders (bacteria), delivered to lysosome to be. Has the hydrolytic enzymes, metabolic waste, water (storage) Have own dna, shorter than nuclear dna, circular. - doesn"t have same number of genes as their free living bacterial counterparts: -kinesin: moves towards + end of microtubule, walks along microtubules, carries organelles, vesicles, requires exchange of adp for. -dynein: moves towards - end of microtubule, walking away. -flagella associated w/ microtubules and dyneins, whiplike mvmts, locomotion. -cilia associated w/ microtubules and dyneins, similar mvmts to flagella, shorter than flagella, when dynein walks it bends then let"s go and goes back, locomotion. Compose nuclear lamina: interior portion of nuclear membrane. Compose flexible networks primarily directly under plasma membrane. Myosin moves towards + end of microfilament.
