Answer:
B. Sugar + O₂→ ATP + CO₂+ Water
Step-by-step explanation:
The flowchart given in the question is steps of cellular respiration. It is a process which takes place all living cells. Glycolysis occurs in the cytoplasm whereas, Krebs cycle and electron transport chain occurs in the mitochnodria. In this process the respiratory substrate such as sugrar is oxidised completely in presence of oxygen to produce ATP, carbon dioxide and water.
