5.      make cellular
products like hormones and lipids. It also distributes those products
throughout the cell and to places in the organism. The smooth ER also regulates
and releases calcium ions and processes toxins. It is described as ‘smooth’ to
distinguish it from rough ER, which has ribosomes for protein synthesis on its
surface.

4.      are microscopic
cellular membrane protrusions that increase the surface area for diffusion and
minimize any increase in volume, and are involved in a wide variety of
functions, including absorption, secretion, cellular adhesion, and
mechanotransduction.

3.      to process and
bundle macromolecules like proteins and lipids as they are synthesized within
the cell. The Golgi apparatus is sometimes compared to a post office inside the
cell since one major function is to modify, sort, and package proteins to be
secreted.

2.      involved in some
protein production, protein folding, quality control and despatch. It is called
‘rough’ because it is studded with ribosomes

1.      Ribosomes on the
rough endoplasmic reticulum are called ‘membrane bound’ and are responsible for
the assembly of many proteins. This process is called translation.
