Catabolic pathways involve the breakdown of nutrient molecules (Food: A, B, C) into usable forms (building blocks). In this process, energy is either stored in energy molecules for later use, or ...

Enzymes control metabolic pathways. The enzymes change the substrate at each step in the metabolic pathway in order to get the final product at the end. There are different types of metabolic ...

anabolic – this type of pathway requires energy and is used to build up large molecules from smaller ones (biosynthesis). catabolic – this type of pathway releases energy and is used to break ...
