Enzymes are needed during the process of digestion.
Lysomes are the organelles responsible for holding chemicals needed for digestion.
enzymes
Chemical digestion is needed to break down large molecules into smaller, absorbable nutrients through enzymes and other substances. Physical digestion helps to further break down food through mechanical processes like chewing, mixing, and churning in the stomach, making it easier for enzymes to act on the food particles. Both types of digestion are essential for the body to effectively extract nutrients from food for energy and growth.

To obtain new substances a chemical reaction is needed.
Light is not a reactant or a product in a chemical reaction because it does not undergo a chemical change. While light can provide the energy needed to drive certain reactions (such as photosynthesis), it is not consumed or produced in the process.
Chemical change is needed to break down a compound. It involves breaking the chemical bonds that hold the molecules of the compound together, resulting in the formation of new substances. This process can be brought about by various means such as heat, light, or the presence of other chemicals.
A degree in Chemical Engineering, is required for employment as a chemical process engineer. A background in physics, chemistry and mathematics is also beneficial.
The liver is primarily responsible for producing substances needed by the body, such as bile for digestion and certain proteins for blood clotting. It also plays a key role in metabolizing drugs and detoxifying harmful substances.
