18 Questions
What is the first step in the process described where DNA is converted to a protein?
The DNA is transcribed into mRNA
What is the role of the ribosome in this process?
The ribosome reads the mRNA and synthesizes the protein
Where does the protein go after it is synthesized by the ribosome?
The protein goes to the Golgi apparatus
What type of modifications does the protein undergo in the rough ER?
The protein is folded and assembled
What is the final form of the protein after it leaves the Golgi apparatus?
A fully packaged glucagon
What is the purpose of the protein synthesis process described in the text?
To produce glucagon in response to low glucose levels
What is the first step in the process of insulin production inside the cell?
The insulin gene undergoes transcription to produce mRNA.
What is the role of the ribosome in insulin production?
The ribosome reads the mRNA and synthesizes the insulin protein.
What is the purpose of the modifications that occur to the insulin protein in the rough ER?
To ensure the insulin protein is properly folded and functional.
What is the main function of the Golgi apparatus in the process of insulin production?
The Golgi apparatus packages the insulin protein into vesicles for secretion.
What is the role of mRNA in the process of insulin production?
mRNA carries the genetic instructions for insulin production to the ribosome.
What is the purpose of the modifications that occur to the insulin protein in the rough ER?
To ensure the insulin protein is properly folded and functional.
What is the mechanism called when Pi3k and Atk convert glucose to glycogen in the liver?
Glycogenesis
Which receptor is stimulated by Pi3k and Atk to allow glucose entry into muscle cells?
GLUT-4
What type of molecule will glucose convert to before entering the muscle cell through GLUT-4?
G-3p
Which step involves conversion of amino acids to proteins in the muscle cell?
Protein synthesis
What is the primary product of the mechanism known as Glycolysis?
ATP
Which process involves the conversion of glucose to pyruvate, acetyl CoA, and then fatty acid chain?
Lipogenesis
Test your knowledge on the process of gene transcription, MRNA synthesis, protein synthesis, and protein packaging in cells. Learn about how glucagon is activated in response to low glucose levels in the body.
