Starch is too large to cross the selectively permeable membrane and must be broken down into simpler molecules
before it is transported to other cells. To do this, starch-digesting enzymes called amylases are formed in the
endoplasmic reticulum (ER) and are transported from cell to cell.
Which of the following best describes the mechanisms by which these enzymes would be transported from the cell
and into a new cell?
O A vesicle from the ER will pass through the plasma membrane via exocytosis, and will then be transported to a
new cell via phagocytosis.
O The enzymes will diffuse across the plasma membrane, and then form a vesicle in the extracellular matrix that will
be engulfed by the new cell via pinocytosis.
O The enzymes will pass through a channel protein to leave the cell, and then form a vesicle in the extracellular
matrix that will be engulfed into the cell via receptor-mediated endocytosis.
A vesicle from the ER will fuse with the cell membrane and release the contents into the extracellular matrix via
exocytosis, and then the plasma membrane will engulf the enzymes via receptor-mediated endocytosis.

Why is the theory of evolution important? it disproves all other theories about how life began. it provides a topic for debate. it is a unifying concept in biology. it explains how life began. i know for sure, it is not "it is a unifying concept in biology."
