Humans lack the enzyme needed to efficiently break down cellulose, the main component of plant cell walls. Unlike herbivores like cows and termites, which have specialized gut bacteria to digest cellulose, humans do not possess this capability. As a result, humans cannot extract significant energy from cellulose as a source of nutrition.

The main source of energy in the human die?

Carbohydrates are the main source of energy for the human body. When consumed, they are broken down into glucose, which is used by the body’s cells as fuel to carry out various functions. Other sources of energy include fats and proteins, but carbohydrates are the body’s preferred and most efficient source of energy.


Why can't the human body break down cellulose?

The human body lacks the enzyme needed to break down cellulose, called cellulase. Cellulase is produced by certain microorganisms like bacteria, fungi, and protozoans, which help them digest cellulose in their diet. Since humans do not produce cellulase, we cannot directly break down cellulose for energy.


What does the appendix has to do with inability to digest cellulose?

The human appendix is a vestigial organ that no longer serves a significant digestive function. It is not directly related to the body's ability to digest cellulose, which is a complex carbohydrate found in plants. Inability to digest cellulose is due to the lack of necessary enzymes in the human digestive system.


What is the most abundant and least expensive source of calories in the human body?

The most abundant source of calories in the human body is glycogen, which is stored in the liver and muscles, while the least expensive source of calories is body fat, which is used as a reserve energy source.


What are substances that provide the energy and raw materials that the human body needs?

Carbohydrates, proteins, and fats are the main substances that provide the energy and raw materials that the human body needs. Carbohydrates are the body's primary source of energy, proteins are essential for building and repairing tissues, and fats are important for energy storage and hormone production. Additionally, vitamins and minerals play a crucial role in various metabolic processes in the body.

What is the difference between the function of glycogen amylase and cellulose?

Glycogen amylase breaks down glycogen into glucose for energy storage in animals, while cellulose is a structural polysaccharide found in plant cell walls that provides rigidity and support. Glycogen amylase is involved in energy release, while cellulose provides structural integrity in plants.
