Which of the following would not move freely across the cytoplasmic membrane?
The cell membrane (also known as the plasma membrane (PM) or cytoplasmic membrane and historically referred to as the plasmalemma) is a biological membrane that separates the interior of all cells from the outside environment (the extracellular space) which protects the cell from its environment. The cell membrane consists of a lipid bilayer including cholesterols (a lipid component) that ...

If the membrane allows the passage of water but not the solute the water will move into the compartment with the greatest solute concentration in order to establish an equilibrium in which the energy of the system is at a minimum. This takes place because the water moves from a high solvent concentration to a low one (in terms of the solute ...
Thu Jun 05 2008 14:30:00 GMT-0400 (Eastern Daylight Time) · Calcium pumps are a family of ion transporters found in the cell membrane of all animal cells. They are responsible for the active transport of calcium out of the cell for the maintenance of the steep Ca 2+ electrochemical gradient across the cell membrane . Calcium pumps play a crucial role in proper cell signalling by keeping the intracellular calcium concentration roughly 10 000 times lower ...
Formation. Primary plasmodesmata are formed when fractions of the endoplasmic reticulum are trapped across the middle lamella as new cell wall are synthesized between two newly divided plant cells. These eventually become the cytoplasmic connections between cells. At the formation site t...
