Answer #1

Aerobic respiration includes three main stages.
i. Glycolysis: Glucose to pyruvate
ii. TCA cycle: Acetyl CoA to CO2
iii. Electron transport chain: Production of ATP driven by proton gradient generated by NADH and FADH2

The transition reaction oxidatively decarboxylates pyruvate to produce Acetyl CoA.

The combustion of glucose releases a large amount of energy (686 kcal/mol) is a single instantaneous step. The energy is released in the form of heat and light.
Living organisms maintain homeostasis in their bodies. If the reaction releases a large amount of energy, homeostasis can be disturbed. ATP is the usable energy form for all living organisms
So, glucose is sequentially oxidized in multiple steps to capture energy in the form of ATP.
