Ek 1001 #251: The nucleus cytoplasm are bound by membranes and contain a c # of structural components that are classified into 2 categories: organelles or inclusions. Which of the follwing is properly categorized as an inclusion?
a. ribosome
b. lysosome
c. fat
d. pigment vacuole
answer: D
why isn't it C also?
EK 1001 278: Many local anesthetics such as cocain, lidocaine, etc seem to dissolve in the hydrophobic core the the membrane and somehow inhibit some of the membrane0boudn proteins. In particular, which of the following channels must be inhibited in order to cause a blockage of nerve conduction?
a. Na channel
b. K channel
c. Ca channel
d. Cl channel
answer: A
why just the Na channel? I know during depoloarizaiton, Na channels open, then repolarization happens when K gates open. Duing synase transmission, Ca channels are in use............
