Energy in ATP is used to power skeletal muscle contraction. This is an example of what type of energy conversion?
- a. chemical energy to mechanical energy
- b. light energy to mechanical energy
- c. chemical energy to light energy
- d. electrical energy to chemical energy
Introduction:
The skeletal system is that organ system that is related to movement. It is composed of skeletal muscles and bones. It consists of 206 bones, tendons, and ligaments. It also provides supports, production of blood cells, calcium storage and regulation of the endocrine system.
Answer to Problem 1DYKB
Correct answer:
Energy in ATP is utilized in providing strength to skeletal muscles for contraction. This is an example of conversion of chemical energy to mechanical energy. Therefore, option a. is correct.
Explanation of Solution
Reason for the correct statement:
Option a. is given as “chemical energy to mechanical energy”. Chemical energy is the energy that is stored in chemicals or compounds. Mechanical energy is that type of energy that is related to motion and position of anything or any organism. When there is a muscular contraction then there is the use of ATP which is a chemical compound. So, there is a conversion of stored chemical energy to mechanical energy as a result of which there is a contraction in the skeletal muscles. Hence, there is the conversion of chemical energy to mechanical energy in the case of muscular contraction.
Hence, option a. is correct.
Reasons for incorrect statements:
Option b. is given as “light energy to mechanical energy”. Energy stored in ATP is chemical energy and not light energy. Hence, option b. is incorrect.
Option c. is given as “chemical energy to light energy”. There is a use of mechanical energy and not light energy in the process of contraction of muscles. Hence, option c. is incorrect.
Option d. is given as “electrical energy to chemical energy”. In ATP there is chemical energy and not electrical energy. Hence, option d. is incorrect.
Hence, options b., c., and d. are incorrect.
In the process of contraction of muscles of the skeleton, there is the conversion of chemical to mechanical energy as the energy stored in ATP is chemical energy.
