Question

quiz 6: cellular respiration quiz
which is the correct sequence of events in aerobic respiration?
o glycolysis → fermentation → krebs
o krebs → electron transport → glycolysis
o glycolysis → krebs → electron transport
o krebs → glycolysis → electron transport

Explanation:

Aerobic respiration first breaks down glucose through glycolysis in the cytoplasm. Then the products enter the mitochondria for the Krebs cycle. Finally, the high - energy electrons from the previous steps are used in the electron transport chain to produce a large amount of ATP. Fermentation is an anaerobic process, so the first option is incorrect. Glycolysis occurs before the Krebs cycle and electron transport in aerobic respiration, ruling out the second and fourth options.

Answer:

Glycolysis → Krebs → Electron Transport
