Diffusion - The movement of molecules from a region of higher concentration to a region of lower concentration.
Facilitated diffusion - This process does not require ATP but does require cell membrane proteins which are called carrier proteins to carry the molecules across the cell membrane from an area of higher concentration to an area of lower concentration
Osmosis - is the movement of water through a semipermeable membrane to a higher concentration of solutes.

Answer:
Glycocalyx
Explanation:
Glycocalyx is carbohydrate rich (glycoprotein + glycolipid) coating that is found in outer surface of cell membrane of many prokaryotic and eukaryotic cells specially bacteria.
Glycoprotein=Carbohydrate + Protein
Glycolipids= Carbohydrate + Lipids
Glycocalyx provied a barrier between cell and its surrounding, adhesion and provide protection in bacteria. In eukaryotes it can be used to identify cells.
Answer:
The enzymatic reactions of cellular respiration begin in the cytoplasm, but most of the reactions occur in the mitochondria. Cellular respiration occurs in the double-membrane organelle called the mitochondrion.
