Question

The correct sequence for aerobic metabolic breakdown of glucose is

• A. glycolysis--preparatory reaction--cirtric acid cycle--electron transport system
• B. preparatory reaction--glycolysis--electron transport--citric acid cycle
• C. electron transport system--citric acid cycle--preparatory reaction--glycolysis
• D. light reactions--electron replacement--ATP production--calvin cycle

Answer 1

The correct option is A

glycolysis--preparatory reaction--cirtric acid cycle--electron transport system

Aerobic respiration is the process of producing cellular energy involving oxygen.
Cells break down food in the mitochondria in a long, multistep process that produces roughly 36 ATP.
The first step in is glycolysis, the second is the citric acid cycle and the third is the electron transport system.
This takes place in the cytoplasm and is common for both aerobes and the anaerobes.
