Autophagy Study guides, Revision notes & Summaries

Advanced Patho NURS 5315 exam 1 action potential The process by which excitable cells transmit information from one to another. How is the action potential altered by a potassium imbalance? (Hyperkalemia) The ECF has more K+ ions. The membrane potential becomes more positive (hypopolarized). Cells become MORE excitable. T waves peak. QRS complexes widen. Causes dysrhythmias, weakness, paresthesia. {If membrane potential becomes equal to threshold potential cardiac standstill occurs}...

Which organelle performs autophagy? a) Proteasome b) cytoskeleton c) Ribosome d) Lysosome - Answer-Lysosome Lysosomes can digest worn-out organelles and release the by products in the cytoplasm. (autophagy=self digestion) -Proteasome degrades malfunctioning/ misfolded proteins to peptides -Cytoskeleton maintains the shape and organization of cell contents -ribosome is large and translates mRNA to proteins Fe+ O2----->Fe203 a) Fe +o2-----> 2Fe2O3 b) Fe+3O2----->2Fe2O3 c) Fe+...
