1 Answer

Answer :

a single strand of protein is wondering in the cell that makes thymine (one bond) connect with another bond called adenine. then the hydrogen bond (a type of surge) goes in between the different bonds and it acts like glue and is used like glue.

What happens when a chemical bond is formed? (1) energy is always absorbed (2) energy in always released (3) more energy is released than is absorbed (4) energy is neither released nor absorbed Correct (4) Answer – (1) energy is always absorbed Explanation: If a bond is broken, energy is released; and if a bond is formed, energy must have been absorbed. As these occur, a change in the chemical energy of the system also occurs. Within each bond of a molecule is an experimentally determined amount of enemy that upon the breaking of that bond is released into the chemical system. The energy within these bonds are 'stored' and can be easily thought of as potential energy. Upon the breaking of these bonds the energy is released thereby creating usable energy.
