Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which sequence correctly traces the path of a protein in the cell?
A
nucleus to ribosome to endoplasmic reticulum to Golgi to cell membrane
B
nucleus to ribosome to endoplasmic reticulum to chloroplast
C
endoplasmic reticulum to lysosome to Golgi to cell membrane
D
mitochondria to endoplasmic reticulum to cell membrane
Explanation: 

Detailed explanation-1: -So, the correct answer is ‘Rough ER →→ Golgi apparatus →→ Cell membrane’.

Detailed explanation-2: -So, the correct answer is ‘Rough ER →→ Golgi apparatus →→ Cell membrane’.

Detailed explanation-3: -What is the correct sequence for secreted protein movement through the endomembrane system? See Section 7.5 (Page 158) . Correct. Synthesized proteins move first to the RER, then through the Golgi for processing, and then travel to various destinations via vesicles.

Detailed explanation-4: -Nucleus → Endoplasmic reticulum → Ribosomes → Golgi apparatus → Lysosomes → Plasma membrane.

Detailed explanation-5: -In eukaryotes, ribosomes get their orders for protein synthesis from the nucleus, where portions of DNA (genes) are transcribed to make messenger RNAs (mRNAs). An mRNA travels to the ribosome, which uses the information it contains to build a protein with a specific amino acid sequence.
