Although most solutes that enter or exit the cell are relatively small (inorganic ions, sugars, or amino acids), occasionally the movement of larger molecules into or out of the cell is required. For example, certain cells secrete proteins, such as pancreatic cells that secrete insulin. Other cells take up food particles or even entire cells, such as lymphocytes in your immune system. Transport of such large materials into and out of the cytosol cannot be accomplished by transport proteins in the plasma membrane. The transport of large molecules is accomplished by bulk transport via exocytosis and endocytosis. Like other forms of active transport, bulk transport requires an input of energy.

Part A

Sort the phrases into the appropriate bins depending on whether they describe exocytosis, endocytosis, or both.

a. decreases the surface area of the plasma membrane

b. requires fusion of vesicles with the plasma membrane

c. forms vesicles from inward folding of the plasma membrane

d. transported substances never physically cross the plasma membrane

e. increases the surface area of the plasma membrane

f. requires cellular energy

g. secretes large molecules out of the cell

a. -->  ENDOCYTOSIS

b. -->EXOCYTOSIS

c.--> ENDOCYTOSIS.

d. --> BOTH

e. --> EXOCYTOSIS

f. --> BOTH

g. --> EXOCYTOSIS

Explanation:

To answer the question, first, we need to know the meaning of endocytosis and exocytosis.

Endocytosis and exocytosis process refers to molecules transport mediated by vesicles. It occurs from and into the cell and needs energy to happen because it is active transport.

Now that we know these concepts, we can sort the phrases into the appropriate bins.

a. decreases the surface area of the plasma membrane. ENDOCYTOSIS, because the new vesicles are formed using the cell membrane

b. requires fusion of vesicles with the plasma membrane. EXOCYTOSIS, because vesicle needs to fuse to the cell membrane to release the carrying material

c. forms vesicles from inward folding of the plasma membrane. ENDOCYTOSIS. Refers to the invagination process of the cell membrane. It only occurs during endocytosis

d. transported substances never physically cross the plasma membrane. BOTH. Substances are too big or too many to be physically transported through the cell membrane

e. increases the surface area of the plasma membrane. EXOCYTOSIS. Occurs when the vesicle fuses the cell membrane to release the content to the exterior.  

f. requires cellular energy. BOTH of them, because they are active transport.

g. secretes large molecules out of the cell. EXOCYTOSIS. The direction is from the interior of the cell to the exterior. These are exportation molecules.
