Option 3 : Pepsin

Pepsin:

Pepsin is the digestive enzyme that breaks down proteins.
The Gastric Glands secrete the enzyme Pepsin.
Gastric glands are found in the stomach.
They secrete enzymes like Pepsin, and Rennin which act upon the Proteins.
Glands in the mucous membrane which line the stomach make and store an inactive protein known as pepsinogen.
When pepsinogen is released into the stomach and mixed with gastric juice, it is converted into pepsin.
Pepsin partially degrades proteins into smaller units called peptides.
Without enough hydrochloric acid, pepsinogen does not convert to pepsin which does not allow for protein breakdown
The hydrochloric acid creates an acidic medium that facilitates the action of the enzyme pepsin in the stomach.

Pepsin	It breaks down proteins into smaller peptides, therefore helping in the digestion of protein.
Lipase	It breaks down dietary fats into smaller molecules called fatty acids and glycerol.
Renin	It eventually causes an increase in blood pressure, leading to restoration of perfusion pressure in the kidneys
Ptyalin	It is a form of amylase found in the saliva of humans and some other animals which lubricates the food in the mouth so that it can easily pass through food pipe.

In the question below, are given a statement followed by three courses of actions numbered I, II and III. On the basis of the information given, you have to assume everything in the statement to be true, and then decide which of the following suggested courses of actions logically follow(s) for pursuing. Statement: High-sulphur fuel oil (HSFO), essentially the leftovers of an oil refiner's output, will still flow from refineries around the world even after new rules start up in 2020 curtailing its use in the global shipping fleet.Sixty percent of the 33 refineries in a global survey will still produce HSFO in 2020 although the supply will tighten as 70 percent of these refiners plan to reduce their output. Courses of action: I. Starting that year, ships will use marine fuel, which primarily consists of residual fuel oil, with a maximum sulphur content of 0.5 percent under International Maritime Organization (IMO) rules to reduce air pollution. II. Currently, the global shipping fleet, which includes oil and chemical tankers as well as container ships, uses as much as 3.3 million barrels per day of HSFO with a maximum of 3.5 percent sulphur. III. Refiners will have little incentive to produce HSFO after the regulations though some demand will remain as a small but growing number of vessels are fitted with smokestack scrubbers that remove the sulphur from the exhaust fumes and power plants will continue to consume the fuel. ?

Option 3 : Pepsin

If the stomach did not produce any hydrochloric acid, then Pepsin enzyme which needs a low pH level provided by the HCl in stomach will not function and hence protein digestion would be affected.
