Answer:
The correct answer is – electron transport system.
Explanation:
There are 3 main stages of cellular respiration (aerobic) that are Glycolysis, the Kreb’s Cycle and the ETS or Electron Transport Chain. The formation of energy in ATPare as follows:
Glycolysis – glucose > 2 Pyretic Acid Molecules =>2 ATP and Hydrogen
The Krebs Cycle – Citric Acid (a derivative of Pyruvic Acid) > 2 ATP in 4 cycles and Hydrogen, carbon dioxide and water.
The Electron Transport Chain > electron carrying Hydrogens > releases the energy as 4 ATP and water
Thus, the correct answer is – The Electron Transport Chain is the stage that produces most of the ATP during cellular respiration.
