Question

The stored food material found in muscles is
A. Protein
B. Glycogen
C. Lipid
D. Phosphogen

Answer 1

Hint: Muscle is a type of specialised tissue originating from the mesoderm (middle germ layer). The muscular tissue is made up of specialised cells called myocytes. Storage, contractibility, elasticity and extensibility.

Complete answer:
The stored food material in muscles is glycogen. Glycogen is a multi branched polysaccharide of glucose and it serves as a form of energy in animals, fungi and bacteria. In humans, glycogen is stored primarily in the cells of liver and skeletal muscle.
Glycogen is a glucose polymer. Glycogenesis is the formation of glycogen from the glucose, it is synthesized depending on the demand of glucose (energy). A hormone known as insulin secreted from the beta cells of the islets of langerhans of pancreas converts glucose into glycogen and sends into muscles and liver as a storage food material. When someone runs, lift heavy weights energy in the form of ATP decreases and to gain the energy stored food material in muscles in the form of glycogen converts into glucose by the secretion of hormone Glucagon and it is secreted by alpha cells of islets of langerhans. This process is known as Glycogenolysis.

So the correct answer is option B.

Note: There are three types of muscles:
> Skeletal/striated/voluntary muscles
> Smooth/non-striated/involuntary muscles
> Cardiac muscles
An inelastic connective tissue that connects bone to muscle known as Tendon.
