Chapter 34: Q. 6 (page 974)

The acidic nature of chyme is neutralized by ________.

a. potassium hydroxide

b. sodium hydroxide

c. bicarbonates

d. vinegar

Short Answer

Expert verified

Option c is the correct answer.

Step by step solution

01

Introduction

The process of digestion involves breaking down large, insoluble molecules into smaller, soluble molecules that may be absorbed by the blood. Gastric fluids and partially digested food in the stomach combine to form chyme. Chyme is moved from the stomach to the small intestine, wherein proteins, carbohydrates, and lipids are completely digested.

02

The explanation for correct answer

Secretin, a hormone, causes the pancreas to create an alkaline bicarbonate solution and transfer it to the duodenum in order to neutralise the acidic chyme.

03

The explanation for incorrect options

The acidic chyme needs to be neutralised in the small intestine. However, chyme is not neutralised by using potassium hydroxide, sodium hydroxide, or vinegar.
