Final answer:
The breakdown of sugars is a catabolic process, while the synthesis of amino acids is an anabolic process.
Step-by-step explanation:
The breakdown of sugars occurs via catabolic pathways, whereas the synthesis of amino acids occurs via anabolic pathways. Therefore, the correct answer to the question is b) Catabolic; Anabolic. Catabolic pathways involve the breakdown of larger molecules into smaller ones, releasing energy in the process. In contrast, anabolic pathways use energy to build larger molecules from smaller ones. These pathways are essential for maintaining the cell's energy balance, as they manage both the construction and deconstruction of molecules within the cell.
