Question

Why is glycolysis considered to be one of the first metabolic pathways to have evolved?

Answer 1

One of the earliest reactions is Photosynthesis and Glycolysis.

Explanation:

Photosynthesis is one of the earliest reactions where carbon dioxide and water come together to form glucose. In glucose the energy of the sun is trapped. Glycolysis breaks down glucose molecules in carbon dioxide and water. Breaking down glucose releases energy.
Most of the cells respire anaerobically. All these cells have glycolysis in their metabolic pathway. Therefore it is one of the earliest metabolic pathways
