During digestion, carbohydrates are broken down to form which of the following compounds?

Glucose

The correct answer is option 1. Glucose.

During the process of digestion, complex carbohydrates are broken down into simpler molecules that can be absorbed by the body. Carbohydrates are primarily found in foods like grains, fruits, vegetables, and dairy products. The main types of carbohydrates are starches, sugars, and fiber.

When you eat foods containing carbohydrates, the digestion process begins in the mouth, where enzymes like salivary amylase start breaking down complex carbohydrates into smaller molecules. However, the majority of carbohydrate digestion occurs in the small intestine.

In the small intestine, enzymes such as pancreatic amylase and intestinal enzymes continue to break down complex carbohydrates into their simplest form. This process involves breaking the bonds between glucose molecules in starches, glycogen, and other complex carbohydrates, leading to the release of individual glucose molecules.

Once broken down into glucose, the molecules are small enough to be absorbed through the walls of the small intestine and into the bloodstream. From there, glucose is transported to cells throughout the body, where it serves as a primary source of energy for cellular processes.

So, during digestion, carbohydrates are broken down into glucose, which is then absorbed and used by the body for energy. Other compounds like amylose and cellulose are forms of carbohydrates, but they are not the end products of carbohydrate digestion. Instead, they are types of starch and fiber, respectively, found in certain foods.
