Digestion
Nutrient molecules pass from the small intestine into the through tiny structures called villi.
Mechanical digestion. The actual grinding and physical breaking down of food. Chemical digestion breaks down food using chemicals/enyzyms and chemical reactions.
The part of the cell brakes down food and old cell parts is call lysosome...
into your small intestine.
After the enzyme amylase breaks down a starch molecule, it breaks it into smaller sugar molecules called maltose.
cellular respiration

something breaks down stored food molecules i think
The organelles where energy is released from nutrient molecules are called mitochondria. These organelles are often referred to as the powerhouse of the cell because they produce the majority of the cell's energy currency, known as adenosine triphosphate (ATP), through a process called cellular respiration.
Fat is broken down through a process called lipolysis, which involves the breakdown of triglycerides into fatty acids and glycerol by enzymes such as lipase. These fatty acids can then be utilized as energy by the body through a process called beta-oxidation.
The process you are referring to is called catabolism. Catabolism involves breaking down large molecules into smaller ones, releasing energy in the process. This process is essential for producing energy and building blocks for anabolic reactions in cells.
Hydrolysis is the chemical reaction that breaks down large molecules into smaller molecules by adding water. Hydrolysis involves the cleavage of chemical bonds through the addition of water molecules.
