Question

During chemical reaction , chemical bonds are

Answer 1

Chemical bonds are broken and formed during chemical reactions. When a chemical bond is broken, it requires energy, and when a chemical bond is formed, energy is released.

Step-by-step explanation:

A chemical bond is the physical process that causes atoms and molecules to be attracted to each other and held together in more stable chemical compounds. During a chemical reaction, bonds are broken and formed. When a chemical bond is broken, energy is required, and when a chemical bond is formed, energy is released.

Answer 2

During chemical reactions, the chemical bonds between atoms are altered. ... Enzymes make chemical reactions take less time by decreasing the activation energy of the chemical reaction. The role of the enzyme-substrate complex is to provide the energy to break or form bonds in chemical bonds.
