context_page_description: An electron transport chain is how a cell gets energy from sunlight in photosynthesis. Electron transport chains also occur in reduction/oxidation reactions, such as the oxidation of sugars in cellular respiration.
  In aerobic respiration, each molecule of glucose leads to about 34 molecules of ATP being produced by the electron transport chain. This is by far the most productive part of respiration.
context_section_description: An electron transport chain (ETC) is how a cell gets energy from sunlight in photosynthesis. Electron transport chains also occur in reduction/oxidation ("redox") reactions, such as the oxidation of sugars in cellular respiration.
  In aerobic respiration, each molecule of glucose leads to about 34 molecules of ATP (Adenosine triphosphate) being produced by the electron transport chain. This is by far the most productive part of respiration.
