Chlorophylls are found embedded in the __________ membranes?
Correct answer: C. Thylakoid
- A. Stroma
- B. Grana
- C. Thylakoid
- D. Intergrana
Explanation
Chlorophyll molecules are embedded in thylakoid membranes, where they form photosystems and absorb light for the light-dependent reactions. The likely alternative is grana, but grana are stacks of thylakoids, not the membranes themselves.

About Cellular Respiration
Cellular respiration releases energy from glucose through glycolysis, the link reaction, the Krebs cycle and the electron transport chain, producing ATP. The pathway differs in oxygen availability: aerobic respiration uses oxygen and yields more ATP, while anaerobic respiration produces much less ATP and forms lactic acid in muscles or ethanol and carbon dioxide in yeast.
