Direction: The following question consists of two statements - Assert...
Assertion : Digestion breaks large complex molecules to simple smaller molecules which can be easily absorbed.
Reason : Digestion is necessary for the absorption of all molecules.
The correct answer is option 'C' - A is true but R is false.
Explanation:
Digestion is the process by which large complex molecules are broken down into simpler molecules that are easier to absorb. This process occurs in the digestive system, where enzymes break down carbohydrates, proteins, and fats into smaller molecules such as glucose, amino acids, and fatty acids.
Assertion (A) is true because digestion does indeed break down large complex molecules into simple smaller molecules. This breakdown allows for easier absorption and utilization of nutrients by the body. For example, carbohydrates are broken down into glucose, which can be easily absorbed and used for energy by cells.
However, the reason (R) is false because not all molecules require digestion for absorption. Some molecules, such as water and certain vitamins, can be directly absorbed by the body without the need for digestion. These molecules are small enough to pass through the walls of the digestive system and enter the bloodstream directly.
In conclusion, digestion is necessary for the absorption of many molecules, especially large complex molecules like carbohydrates, proteins, and fats. However, there are also molecules that can be directly absorbed without the need for digestion. Therefore, Assertion (A) is true but Reason (R) is false.
