Why is cellulose not digested by human beings?

Question

Answer

Why is Cellulose not Digested by Human Beings?

Cellulose is a type of complex carbohydrate that is found in the cell walls of plants. Although it is an important component of many plant-based foods, it is not digestible by humans. This is due to several factors:

Structure: Cellulose has a unique structure that makes it difficult for human digestive enzymes to break down. Unlike other types of carbohydrates, which have a simpler structure, cellulose is made up of long chains of glucose molecules that are held together by strong bonds.

Lack of Enzymes: Humans lack the enzymes necessary to break down the bonds that hold cellulose together. While other animals, such as cows and termites, have specialized digestive systems that allow them to break down cellulose, humans do not.

Fiber: While cellulose is not digestible by humans, it is still important for our diets. Cellulose is a type of dietary fiber that helps to promote healthy digestion and prevent constipation. It also helps to regulate blood sugar levels and lower cholesterol.

Overall, while cellulose may not be digestible by humans, it still plays an important role in our diets. By consuming plant-based foods that contain cellulose, we can help to promote healthy digestion and overall health.

Answer

Due to the absence of cellulose digesting enzymes

Answer

Cellulose is a carbohydrate than can be digested by ruminants but animals including humans cannot digest cellulose. Animals like deer, cattle etc bacteria present in rumen helps in the digestion of cellulose. So humans cannot digest cellulose

Answer
