Answer:
Pepsinogen is a powerful and abundant protein digestive enzyme secreted by the gastric chief cells as a proenzyme and then converted by gastric acid in the gastric lumen to the active enzyme pepsin.
Explanation:
The role of pepsin and its precursor in protein digestion was first described in the 19th century.
Answer:
At least 50% of the tetramers will be inactive for this individual
Explanation:
A protein resulting from a mutation that is dominant negative will have an detrimental impact on the wild-type protein as well. Especially if the mutated protein can interact with the same substances as the normal, wild-type protein.
For an individual who is heterozygous, there will be one wild-type copy and one mutant copy of the allele present. For each copy, a protein will be expressed and the tetramers from the mutant copy will be defective - so 50% of the protein tetramers will be inactive at least.
