Question 1 (1 point)
Choose all of the following that correctly states how a plasma membrane serves the human cell.
Question 1 options:
cell membrane and cell wall work together to achieve structural support
communication between cells is possible owing to proteins located on the external surface of the membrane
proteins in the membrane regulate the movement of dissolved solutes between ICF and ECF
a cell membrane promotes the interaction between ICF and ECF by forming a bilayer membrane
cell membrane and cell wall work together to achieve structural support
communication between cells is possible owing to proteins located on the external surface of the membrane
proteins in the membrane regulate the movement of dissolved solutes between ICF and ECF
a cell membrane promotes the interaction between ICF and ECF by forming a bilayer membrane
Explanation / Answer
Cell membrane along with cellwall provides structural support in plants but not in animals or human cells as cellwall is absent in these organisms. The plasma membrane assists in membrane transport in all organisms. The cells have communication through plasma membrane's integrated, transmembrane and peripheral proteins. The proteins of the plasma membrane also help to regulate the movement of dissolved solutes between intracellular (ICF) and extracellular fluids (ECF). ICF and ECF interact through mediation of plasmam membrane on either side of lipid bilayer. Therefore, options 2, 3 and 4 are correct.
