Catabolism
Catabolism is the breakdown of food components (such as carbohydrates, proteins, and fats) into their simpler forms, which can then be used to provide energy and the basic building blocks needed for growth and repair.
Anabolism
Anabolism is the metabolic process by which your body is built or repaired. This process takes smaller units like nutrients, cells, or amino acids and bonds them together to create bigger structures. Anabolism requires energy that ultimately comes from our food.
