It will enable gut enzymes to act on the bolus during digestion.
Explanation:
The acidic presence of HCl (hydrochloric acid) in the gastric juice serves as a stimulus for the intestinal wall to produce secretin.
This hormone will act on the pancreas by stimulating the production of pancreatic juice that will contain <u>enzymes</u> (trypsinogen, amylase, lipases) and <u>HCO3⁻</u> (bicarbonate) salts, which have base composition.
With this composition that will be sent to the duodenum, there will be neutralization of acidic solution coming from the stomach and pH leveling around 8.0 (slightly basic) which is great for the enzymes that work there.
Plants make up most of our oxygen here on earth, because of the carbon cycle and photosynthesis. They take carbon dioxide, and turn it into oxygen. And not only that, but some animals live in trees to protect themselves from birds and other animals.
It is only active at a pH of around 2 because that is around the same pH as the gastric juices in the stomach which is where pepsin is used to break down proteins.
