In which part of food molecules is energy primarily stored?
A
In the nucleus of atoms
B
In the electrons orbiting the nucleus
C
In the spaces between molecules
D
In the chemical bonds between atoms
Verified step by step guidance1
Understand that energy in food molecules is stored in the form of chemical energy, which is a type of potential energy.
Recognize that chemical energy is primarily stored in the chemical bonds between atoms within molecules. These bonds include covalent bonds, where atoms share electrons.
Learn that breaking these chemical bonds during metabolic processes releases energy that can be used by cells for various functions, such as ATP production.
Clarify that the nucleus of atoms and the electrons orbiting the nucleus are not the primary locations for energy storage in food molecules. Energy is not stored in the spaces between molecules either.
Conclude that the correct answer is: 'In the chemical bonds between atoms,' as these bonds are the primary source of stored energy in food molecules.
