Welcome back. Let's look at our next problem, choose the correct function of the hcl secreted by the parietal cells in the stomach. Hcl is hydrochloric acid in the environment of the stomach. It is a very strong acid creating a very low ph in the stomach. So let's look at our answer choices. We do have the all of the above so we need to be aware that all of them might end up being correct. So let's take a choice a breakdown of food Well in a very acidic environment caused by hcl secretion that will denature and break down the proteins in food. So a is a function of hcl secretion. Choice B is activation of Pepsi in again and yes, steps in again when exposed to an acidic environment. So like that caused by the secretion of hcl in the stomach, it unfolds cleaves itself and becomes epson and Pepsi and goes on to break down proteins into smaller polyp peptides as part of digestion. So that is another function of hcl secretion activation of Pepsi in again. Finally ceased as prevention of infections. This is another function because that's extremely acidic environment can kill most germs that might enter the digestive system through food that's ingested. So Choice C also represents another function of the hcl secretion. So our correct answer is d all of the above. Our functions of that hydrochloric acid secretion in the stomach. See you in the next video
