Enzymes in your gastrointestinal tract digest your lunch. these chemical reactions are categorized as catabolism.
<h3>What is
catabolism?</h3>
The series of metabolic processes known as catabolism reduces molecules into smaller pieces that are then either oxidized to produce energy or utilised in other anabolic processes. Large compounds are divided into smaller components through catabolism.
<h3>What is a prime illustration of catabolism?</h3>
Catabolism happens as you are breaking down food. For instance, a piece of bread is broken down into simple components your body may absorb, such glucose, through this process (blood sugar).
<h3>What is difference between catabolism and anabolism?</h3>
The series of metabolic processes known as catabolism reduces molecules into smaller pieces that are then either oxidized to produce energy or utilised in other anabolic processes. The process of anabolism produces the molecules the body needs to function. Energy is released during the catabolism process. Energy is needed for anabolic processes.
