Final answer:
The secretory pathway involves the steps of Protein Folding, Post-Translational Modification, and Secretion, starting with transcription followed by translation. The correct option is b.
Step-by-step explanation:
The secretory pathway refers to the process by which proteins are synthesized, processed, and transported out of the cell. In terms of protein synthesis specifically, mRNAs are process before they leave the nucleus and contain the codons which dictate the amino acid sequence of the resulting polypeptide.
The correct steps involved in the secretory pathway that lead to protein production are: Protein Folding, Post-Translational Modification, Secretion. This process begins with transcription, where the DNA is used to make RNA, including messenger RNA (mRNA), which exits the nucleus and enters the cytoplasm.
Ribosomes then use the mRNA sequence to synthesize the protein through a process called translation. This protein can then undergo various modifications such as folding and post-translational modification before it is secreted from the cell. The correct option is b.
