Pictured here is the movement of Na* and K* across a cell membrane. Is facilitated diffusion used to move the ions? Why or why not?
A)
Yes, this is facilitated diffusion because of the use of membrane proteins.
B)
No, this is not facilitated diffusion because ions are moving from low to
high concentration.
C)
Yes, this is facilitated diffusion because charged molecules are utilizing
membrane proteins to move against the concentration gradient.
D)
No, this is not facilitated diffusion because because charged molecules are
utilizing membrane proteins to move against the concentration gradient.

these macromolecules could either be amino acids, proteins or nucleic acids. they are responsible for the chemical changes and reactions that affects largely the cell and its composition. take for instance the cytoplasm of the cell where these organelles are settled. these simple organelles are composed of macromolecules which ignites and catalyses different functions that enables cells, in macro-perspective in motion and metabolism. in intestines for example, metabolism happens and breaking down parts of a food to simpler compounds that are used and these nutrients delivered throughout the body and again broken down by into smaller components.
