CARBS
Carbohydrates provide the quickest energy for tigers.
CARBS
It depends on what is moving across the membrane. Some molecules use transport proteins and the cell would need those embedded in the membrane. Water doesn't need them and it freely moves in and out.
there is no "paper" molecule... rather a combination of starches and protein links e.t.c.
Facilitated diffusion uses proteins to move a molecule across the cell membrane without energy.
The water molecule become polar.
Ionic compound
Carrier proteins are a type of molecule that can be used as a tunnel to move compounds across the cell membrane. These proteins bind to specific molecules and undergo conformational changes to transport them across the membrane. This process is known as facilitated diffusion.
About 10 hours at quickest, if you cut across the rez to Flagstaff.
hydropolactive.
Ionic compound
it is carring substances both into and out of the cells.
