Pepsinogen is produced by __________ and is activated by __________
Ket [755]

Answer:

Pepsinogen is produced by chief cells and is activated by hydrochloric acid secreted by parietal cells.

Explanation:

Pepsinogen is a proenzyme produced in the chief cells (that are located in the stomach lining) that, when gets activated, is transformed into pepsin - a peptidase with the function to degrade proteins into amino acids.

The reason why pepsinogen is released inactive is that it would break down all of the cell's proteins because of its proteolytic nature. For this reason, it is released as a proenzyme and gets activated when reaches the acidic environment provided by the hydrochloric acid secreted by the parietal cells, also in the stomach lining.

Original Codon: CTC GAG
Vesna [10]

The original codons code for Leucine and Glutamic acid. The mutated codons code for Valine and Glutamine.

<h3>Genetic codes and amino acids</h3>

Each of the genetic codes. otherwise known as codons, translates to an amino acid.

Following the table of genetic codes with their respective amino acids:

  • CTC (CUC) codes for Leucine
  • GAG codes for Glutamic acid
  • GTC (GUC)codes for Valine
  • CAG codes for Glutamine

Thus, the glutamic acid in the original codon has been replaced with glutamine in the mutated codon while Leucine has been replaced with Valine.
