Cell Transport Homeostasis PPT
... Activation of the _______ fiber allows some of this Ca2+ to pass by fascilitated diffusion into the cytosol where it triggers contraction. After contraction, this Ca2+ is pumped back into the sarcoplasmic reticulum. This is done by a Ca2+ ATPase that uses the energy from each molecule of ATP to pump ...

Transporting across the cell membrane
... The cell membrane is composed of a phospholipid bilayer. The heads of the bilayer can interact with water because they are polar. The tails of the bilayer cannot interact with water because they are nonpolar. Therefore, water soluble molecules cannot move through the bilayer easily. ...
