Final answer:
Humans convert the chemical energy from consumed food into kinetic energy, which is demonstrated when riding a bicycle. This conversion involves the transformation of chemical energy into ATP, which muscles use to exert physical force and motion.
Step-by-step explanation:
An example of a living thing converting chemical energy into kinetic energy is a human riding a bicycle. In this process, the chemical energy from the food consumed, like an ice cream cone, is transformed through a series of cellular chemical reactions into energy within molecules of ATP (Adenosine triphosphate). This energy in ATP molecules is then used by the muscles to contract, thus creating the kinetic energy necessary for riding the bicycle.
The challenge for all living organisms, including humans, is to obtain energy in the form that they can transform into usable energy to perform work such as movement. As cells perform various types of work such as building complex molecules, powering the motion of cilia or flagella, and contracting muscle fibers, they effectively convert chemical energy stored in organic molecules into kinetic and other forms of energy.
