Which is a correct statement about the Na+/K+ transporter (pump), and its cytology and cellular role?     It is found the basal side of intestinal epithelial cells, pumping Na+ out of the cell into the blood.     It is found on the plasma membrane of neurons, pumping Na+ into axons from the blood.     It is found on the membrane of the lysosome, pumping K+ into the lumen of the lysosome.     It is found on the apical side of intestinal epithelia, pumping K+ into the lumen of the intestine.

a. The concentration of sodium ions is             inside the cell . b. The concentration of potassium ions is           inside the cell . c. The concentration of calcium ions is higher                  .

Label A-F as the following: -Nuclei of fat cells -Nuclei -Adipose tissue -Smooth muscle tissue -Smooth muscle cell -Vacuole containing fat droplet

Select the correct statement regarding the actin cytoskeleton.     They are involved in the formation of the axoneme.     Actin microfilaments are the most stable cytoskeleton network.     Can undergo catastrophe due to GTP hydrolysis-mediated conformational changes.     Synthesis and degradation of actin microfilaments is directional, with g-actin subunits added only to the + end of the microfilament while depolymerization occurs at the - end.   From the list below, select the correct statements regarding the genetic code.     Codons code for 30 distinct amino acids.     The basis of the genetic code are codons.     The genetic code has a possible 64 different codons.     The genetic code has built-in degeneracy.     Codons are formed by 5 consecutive nucleotides.
