The correct answer is option 2. glucose.

The starches found in breads, cereals, and pasta are made up of long chains of glucose. So the answer is: glucose.

Here's why:

Starch: This is a complex carbohydrate found in plants and serves as a form of energy storage.

Glucose: This is a simple sugar, also known as blood sugar, and is the primary source of energy for our bodies.

Cellulose: This is another carbohydrate but serves primarily as a structural component in plant cell walls. It is not readily digestible by humans.

Maltose: This is a simple sugar formed by the linkage of two glucose molecules. While present in small amounts in some starches, it's not the main building block.

Galactose: This is another simple sugar but is not a major constituent of starches.

Therefore, the long chains of glucose molecules in starch provide our bodies with readily available energy for various functions.
