<u>Mucins</u> are water-soluble, complex glycoproteins that are secreted by goblet cells.
Explanation:
Goblet cells, named after their goblet-like shape, are usually found in the epithelium of respiratory and intestinal tracts in the body. Their main function is to produce mucus (primarily made up of mucins), a slippery combination of proteins, water and sugars, that serves three main functions:
- The barrier function: By trapping the unwanted/harmful particles that we inhale and preventing them from entering our system.
- The protection function: By keeping the hair-like cilia lubricated and moist to remove the harmful particles.
- The defence function: Mucus is made up of certain enzymes, antibodies and proteins that act as a defence mechanism for the body.
A unique property of mucins is their capability to form gels - sticky and viscous substances that work both as lubricants as well as defensive chemical barriers in the body.
Osmosis: movement of water molecules from an area of higher concentration to an area of lower concentration through a semipermeable membrane.
Osmosis calculations: equation is π=iMRT
π is not equal to 3.14159 in this situation. π stands for the osmotic pressure and is usually expressed in the pressure unit of atmospheres.
Diffusion: the random movement of molecules from an area of higher concentration of those molecules to an area of lower concentration.
Prokaryotic cells: unicellular organisms that lack organelles or other internal membrane-bound structures.
Eukaryotic cells: organisms whose cells have a nucleus enclosed within membranes, unlike prokaryotes.
Mitosis: cell division in which the nucleus divides into two nuclei containing the same number of chromosomes with an end result of two identical cells.
Stem cells: an undifferentiated cell that is capable of dividing and giving rise to one or more distinct types of specialized cells.
