Answer: The Cerebellum's Granule Cell is the smallest cell in the human body that is between 4 micrometers to 4.5 micrometers long.
Explanation:
Involves the elimination of a small molecule
A protein is a large sequence of amino acid that was translated in ribosomes (or rough endoplasmic reticulum) from a mRNA that was transcribed in the nucleus from DNA.
If the protein has an extracellular function (like immunoglobulin) if should be
exocytosed from the cell.
The protein in the cell is driven to the membrane into
vesicles that have
a specific receptor, which allows, while in contact with the inner side of the cell membrane to open it and let the protein being transported in the extracellular medium.
