Small uncharged substances enter and leave the cell membrane through passive diffusion. This process relies on the concentration gradient and does not require energy input from the cell.
Enzymes are the substances that enter the food vacuole in amoebas to break down the food into smaller molecules that can be absorbed by the cell. These enzymes help in the process of digestion within the food vacuole.
cell membrane
Enzymes are usually too large to pass through the cell membrane on their own. They are often synthesized inside the cell and remain in the cytoplasm, where they can catalyze various reactions. In some cases, specific transport proteins on the membrane can help enzymes enter the cell from the extracellular environment.

Either active transport, passive transport, or facilitated diffusion
cell membrane
Enzymes are transported out of a pancreas cell through a process called exocytosis. In this process, the enzymes are packaged into vesicles within the cell, which then move toward the cell membrane. Upon reaching the membrane, the vesicles fuse with it, releasing their contents into the extracellular space. This is a critical mechanism for the secretion of digestive enzymes into the digestive tract.

Materials enter and leave the cell through the process of passive and active transport. Passive transport includes diffusion, osmosis, and facilitated diffusion, while active transport involves the use of energy to move molecules against their concentration gradient. Additionally, materials can also enter and leave the cell through endocytosis and exocytosis, which involve the cell membrane forming vesicles to take in or expel large particles or molecules.
Proteins made on "bound" (attached) ribosomes leave through the cell membrane, and other proteins will enter the cell.
