Question

On hydrolysis of starch, we finally get

• A. glucose
• B. fructose
• C. Both (a) and (b)
• D. sucrose

Answer 1

The Correct Option is A

To understand the hydrolysis of starch, let's break down the chemical process involved:

Starch is a polysaccharide composed of a large number of glucose units joined by glycosidic bonds. During the hydrolysis of starch, these glycosidic bonds are broken down, leading to the formation of simpler sugars.

1. Starch consists mainly of two molecules: amylose and amylopectin. Both are polymers of glucose.
2. The hydrolysis process breaks these polymers down into their monosaccharide components, under the action of enzymes like amylase.
3. Finally, the hydrolysis of starch results in the formation of glucose.

Now, let's consider the given options:

• Glucose: This is the correct answer, as detailed in the explanation above.
• Fructose: Fructose is not a product of starch hydrolysis. It is a different monosaccharide found in other sugars like sucrose.
• Both (a) and (b): Incorrect, because only glucose is formed from starch hydrolysis, not fructose.
• Sucrose: Sucrose is a disaccharide composed of glucose and fructose, not a product of starch hydrolysis.

Therefore, the correct answer is glucose.

In summary, starch undergoes hydrolysis to yield glucose, which can be further utilized in various metabolic processes in living organisms.
