Question

Carbohydrate stored in both the liver and muscle of animals is
A. Glucose
B. Sucrose
C. Starch
D. Glycogen

Answer 1

Hint: Carbohydrates are organic molecules formed by carbon, hydrogen, and oxygen. Carbohydrate is one of the essential nutrients required by the body to function properly. Complex carbohydrates are broken down in the body and utilized as energy. Food reserve in plants is starch and in animals it is glycogen.

Step by step answer:Animals are complex organisms that involve various types of complex life processes. All of the metabolic functions and life processes need the energy to perform work. Energy is derived from food that contains various essential nutrients. Carbohydrate is one of the nutrients required by the body for energy production. Glucose is also a basic sugar that is converted into glycogen inside the animal cells. This glycogen is stored in the cells and acts as a food reserve.
The two main storage sites of glycogen are muscles and the liver. Glycogen is a multi-branched polysaccharide that has the potential to serve as a long term energy reserve. The glycogen stored in muscles is used as an immediate resource of energy when required. During exercise, the glycogen in muscles is broken down through the glycolysis process. This results in the energy production required for exercising. The glycogen reserve in the liver is meant for the long term reserve. It is meant to be used in case of an emergency like starving. In these situations, glycogen from the liver is broken down in energy and is transported to vital body organs like the brain, heart, etc.
Therefore we can conclude that glycogen is the carbohydrate that is stored in both the liver and muscles of the body.
Hence, option D is the correct answer.

Note:Glycogen is one of the two forms of energy reserves in the body. Glycogen is generally a short-term storage source. The other one is triglycerides in adipose tissue is meant for long-term storage. It is also termed as body fat.
