3 0

Carrier proteins differ from channel proteins in their role as gatekeepers of the cell in the sense that carrier proteins bind to the substances they transport across the membrane via facilitated diffusion, whereas channel proteins provide a pore for substances to move across the membrane via facilitated diffusion.

Summarily, Carrier proteins BIND TO THE SUBSTANCES while Channel proteins PROVIDE A PORE FOR SUBSTANCES TO MOVE ACROSS.

Amino acids with hydrophobic r groups are most often found buried in the interior of folded proteins. true or false

pentagon [3]

Answer:

True

Explanation:

Hydrophobicity is the aversion to the water of a molecule (or part of it). Amino acids with a hydrophobic R group (glycine, alanine, valine, leucine, isoleucine, proline, phenylalanine, methionine, and tryptophan) <em>will fold with the R groups in the interior to avoid water. This behavior is one of the most important forces in protein folding. </em>You can see it exemplified in the image I added.
