Physical digestion is the term for breaking down large food molecules into small molecules. Mechanical digestion and physical digestion mean the same thing.
The breakdown of large molecules into smaller ones to be absorbed by cells is called digestion. This process involves the breakdown of carbohydrates, proteins, and fats into their smaller components (such as glucose, amino acids, and fatty acids) that can be readily absorbed and used by the body.
chemical digestion
Catabolism is the breakdown of larger, more complex molecules into smaller, simpler ones.Energy is released and some is trapped and made available for work.
breakdown of large molecules to smaller ones by the addition of water
Hydrolysis
We call the chemical that breaks down large molecules of food into smaller molecules "enzymes." Enzymes play a crucial role in the digestion process by catalyzing the breakdown of macromolecules like proteins, carbohydrates, and fats into smaller units that can be absorbed by the body for energy and nutrients.
One example is hydrolysis, where water is used to break the bonds between molecules. Another example is oxidation, where molecules lose electrons and break into smaller fragments. Both of these reactions result in the breakdown of larger molecules into smaller ones.
Large food molecules are first broken down into smaller molecules through hydrolysis reactions. Enzymes facilitate this process by catalyzing the breakdown of bonds within the large molecules. The resulting smaller molecules can then be absorbed and utilized by the body for energy or building processes.
Mechanical breakdown makes food smaller so it wasn't be so large for the chemical breakdown.
This process is known as hydrolysis. Digestive enzymes catalyze hydrolysis by breaking down large molecules into smaller molecules by adding water molecules. The enzymes facilitate the reaction by weakening the chemical bonds in the substrate molecules, allowing for the release of smaller products.
Digestive enzymes break down large food molecules into smaller molecules in the digestive system. These enzymes break down proteins into amino acids, carbohydrates into sugars, and fats into fatty acids and glycerol. This breakdown process allows the body to absorb and utilize the nutrients from food.
