Locomotion and Movement

Question

During strenuous excercise, glucose is converted into

  • glycogen

  • pyruvic acid

  • starch

  • lactic acid

Answer

D.

lactic acid

During strenuous excercise, anaerobic respiration of glucose takes place and Pyruvic acid (a product of glycolysis of glucose) changes into lactic acid. Accumulation of lactic acid is responsible for muscle fatigue. Glycogen is a polysaccharide and stroing material of animal body. It is stored in muscle and liver.

Starch is also a polysaccharide but a storing material of plant body.
