A Science Odyssey: DNA Workshop: Protein Synthesis

PPI plays a big role in the cell-signalling cascade; for instance, dephosphorylation of glycogen synthase by protein phosphatase-1 results in glycogen synthesis.

Since many of the proteins made are enzymes, genes control the cell's internal chemistry.

Interestingly, a single bout of exercise stimulates protein synthesis within 2-4 hours after the workout which may remain elevated for up to 24 hours (Rasmussen and Phillips, 2003).

Protein Synthesis -Translation and Regulation

Protein Synthesis is the process whereby DNA codes for the production of essential proteins.

It is suggested that the new, popular periodization models of exercise training, which include light, moderate and high intensity training phases, satisfactorily overload the different muscle fiber types of the body while also providing sufficient rest for protein synthesis to occur.


The smooth endoplasmic reticulum plays a major role in synthesizing by means of enzymes embedded in these smooth membranes. It produces the and used in membrane formation, and along with the membrane proteins produced by the rough ER it can synthesize more membrane for itself, for the Golgi complex, the , , and others.

Protein Synthesis in the Liver - Provet Pet Health Information

Before the
synthesis of a protein begins, amino acids are attached to the tRNA
molecule, which transport and attach them to the mRNA with the aid of
rRNA, this is known as translation.


The IGFs play a primary role in regulating the amount of muscle mass growth, promoting changes occurring in the DNA for protein synthesis, and promoting muscle cell repair.
Insulin also stimulates muscle growth by enhancing protein synthesis and facilitating the entry of glucose into cells.
