Question

Would you describe metabolic pathways as inherently wasteful or inherently economical, and why?

a) Inherently wasteful; involve excessive energy consumption
b) Inherently economical; maximize energy efficiency
c) Both wasteful and economical aspects
d) Neither wasteful nor economical

Answer 1

Metabolic pathways are inherently economical as they maximize energy efficiency by efficiently breaking down larger molecules for energy and synthesizing larger molecules that require energy. These pathways work in coordination to maintain the cell's energy balance.

Step-by-step explanation:

Metabolic pathways can be described as inherently economical because they maximize energy efficiency. These pathways involve a series of interconnected chemical reactions that allow for the efficient breakdown of larger molecules to generate energy (catabolic pathways) and the synthesis of larger molecules that require energy (anabolic pathways). These processes work together to maintain the cell's energy balance. Additionally, metabolic pathways often utilize feedback inhibition and the sharing of intermediates between pathways, further optimizing energy usage.
