Question

If the pH of the stomach is made 7, which component of food would be affected?
(a) Starch
(b) Protein
(c) Fat
(d) Sucrose

Answer 1

Hint: It is the structural block of the body. Digestion starts inside the mouth. At the point when we bite the food, it's mixed in with saliva, which supplies dampness as well as the carbohydrate digestion enzyme, amylase. When we eat crude food, its proteins work with the salivary amylase to start digestion.

Complete answer:
When the pH of the stomach is made 7 then protein digestion will affect as pepsin work as a pH of 2 to 3 and it does not activate because the enzyme is highly precise about their function.

Additional Information: The stomach plays a critical role within the early stages of food digestion. Asides from crushing and stirring the food bolus, it additionally secretes a blend of mixes, aggregately alluded to as "gastric juice." Digestive juice contains water, bodily fluid, acid, pepsin, and factor of those five segments, pepsin is the essential enzyme associated with protein absorption. It separates proteins into more modest peptides and amino acids which will be handily retained inside the digestive system. Particular cells inside the gastric lining alluded to as chief cells, discharge pepsin in an inactive form, or zymogen structure, called pepsinogen. Pepsin relies upon an acidic climate for protein digestion. Therefore, it's best at a pH of roughly 1.5 to 2.
Low pH permits pepsinogen to separate itself and structure dynamic pepsin. At the point when it arrives at the duodenum, however, it accepts an inactive form because the pH rises above 6.
So, the correct answer is ‘Protein’.

Note: Protein digestion continues to require place throughout the tiny intestines via the consequences of pancreatic enzymes: trypsin, chymotrypsin, elastase, and carboxypeptidase. As such, pepsin isn't essential for all times, and protein digestion can still happen within the absence of pepsin. it's worth mentioning that pepsin remains structurally stable until a minimum of a pH of 8.
