The carbohydrates produced by plants are an important source of energy for animals. When animals eat plants, energy stored in carbohydrates is released in the process of respiration, a chemical reaction between glucose and oxygen to produce energy (for cell work), carbon dioxide, and water.tarch is the usual form in which carbohydrates are stored as energy by plants. Plants can split starch into its simpler glucose units for use as energy when needed. Cellulose is known as a structural carbohydrate because of the fibers formed by its molecules.
the DARPA âcheetahâ is the worldâs fastest running robot, capable of moving at speeds up to 18mph engineers of DARPA (the US defense advanced research projects agency) have set a new land speed record for a legged robot with the âcheetahâ, capable of galloping at speeds of up to 18mph.
Astronauts are by far the fastest traveling humans with the earth as a stationary reference point. One might think the Apollo missions to the moon are the fastest traveling humans, but the speed of that spacecraft was only about 6,300 miles per hour. In fact, an orbiting space shuttle is much faster at 17,600 miles per hour. This is the fastest any man has reached. Although it seems very fast to us, this speed is 0.026% of the speed of light. For unassisted speed using Usain Bolt's time in the 100 meter, his top speed is 23.3 miles per hour (10.4 m/s).
