- 1The clear, structureless gel in a cell is itsCYTOSOL
- 2The Na+ -K+ pump isA TRANSMEMBRANE PROTEIN
- 3This process can occur only in the plasma membrane of a living cellACTIVE TRANSPORT
- 4Cells specialized for absorption of matter from the ECF are likely to show an abundance ofMICROVILLI
- 5Aquaporins are transmembrane proteins that promoteOSMOSIS
- 6Membrane carriers resemble enzymes except for the fact that carriersDO NOT CHEMICALLY CHANGE THEIR LIGANDS
- 7The cotransport of glucose derives energy fromAN Na+ CONCENTRATION GRADIENT
- 8The function of cAMP in a cell isTO ACTIVATE KINASES
