CELL BIO 353

As you organize the outline you are going to use please use the following 4subtitles/categories I provide below. <- Divide your answers into these categories.  In a bullet/outline form simply name the component (RNA, protein, membrane etc.) used, in the order used, and where appropriate add a brief descriptor of that component. <- this should take no more than 1 line. Explain what happens at the category AND how the new lipid and protein transit to the next category again using a simple bullet/outline form.   The categories are:

A. Before ER

B. At the ER and how it transports to the Golgi

C. At the Golgi and how it transports to the plasma membrane.

D. At the Plasma Membrane

Effectively you are starting with an mRNA in the cytoplasm and processing it all the way through Constitutive and/or Regulative exocytosis. Be sure to include where new lipids are synthesized and how they move with the protein. Don't forget to include the recycling of components when they occur.

Explanation / Answer

A -

B -

Endoplasmic reticulum - It's a double membrane-bound organelle situated close to the nucleus. It is divided into the rough endoplasmic reticulum and the smooth endoplasmic reticulum.

lipid synthesis -

C -

Golgi apparatus - It is a membrane bound cell organelle which is responsible for packaging and transporting.

D-

Plasma membrane - phospholipid bilayer embedded with proteins.

The lysosomes are involved in the recycling of constituents of the cell. it digests any unwanted DNA, proteins, lipids etc.
