Protein synthesis begins in the cell nucleus. A given gene (made of DNA) is activated, and it then creates RNA which travels to the ribosomes of the cell, which are essentially microscopic protein factories. The RNA gives the design of the protein, and the ribosomes create the protein based on that design. The raw material for the proteins, which is amino acids, is already present in the cell's cytoplasm.

How does prokaryotic cells secrete proteins?
Proteins that are excreted by prokaryotes are synthesized on ribosomes that are bound to the cytoplasmic surface of the plasma membrane.
What are proteins that are transported in vesicles made by?
Transport vesicles play a key part in moving molecules to and from the membrane-confined chambers of the secretory pathway. Proteins are transported in vesicles; the proteins are made on the cytosolic side of membranes.
Proteins are synthesized from less complex organic compounds known as what?
Proteins are synthesized from amino acids.
What are the protein molecules in a cell membrane that assist in cell transport?
Protein molecules are responsible for membrane transport. In passive transport diffusion is the phenomenon in which molecules flow naturally from areas of high concentration to lower concentrations.
What is the membrane that surrounds the cells?
this is the cell membrane made primarily of lipid molecules with proteins incorporated into it that aid in transport of molecules across the membrane
Where are Secretory proteins and membrane molecules are synthesized mainly by what?
Rough Endoplasmic Reticulum
How does prokaryotic cells secrete proteins?

The membrane receptors are proteins that would be synthesized on ribosomes where?
membrane receptors are proteins that would be synthesized on ribosomes on the rough endoplasmic reticulum
Where does synthesis of membrane proteins and secretory proteins happen?
Synthesis of proteins occurs in the Rough Endoplasmic Reticulum.
Is it true that the Ribosomes endoplasmic recticulum and the Golgi apparatus functionally act in sequence to synthesize and modify proteins for a secretory use only never for use by cell?
false; integral cell membrane proteins are also synthesized this way

2 integral membrane proteins such as transport proteins are permanently attached to cellular membranes after integral membrane proteins are synthesized which organelle would aid in transporting?
Proteins are often synthesized by ribosomes on the rough Endoplasmic Reticulum.
Which of these is not an essential role of salts in the body neuromudcular activity membrane permeability secretory activity or anabolism or proteins?
Anabolism of proteins is NOT an essential role of salts. Roles include: Controlling fluid movements, Excitabilty, Secretory activity, and membrane permeabilty.
Membrane proteins are synthesized on ribosomes that are found?
the endoplasmic reticulum
What biomolecule helps transport molecules across the membrane?
proteins
What molecules located in the membrane assist with facilitated diffusion?
Usually proteins are the molecules doing the selection of what other molecules get into or out of a cell.
Proteins are synthesized from less complex organic compounds known as what?
Proteins are synthesized from amino acids.
