Chlorophyll are found embedded in the_membranes.
Correct answer: C. Thylakoid membrane
- A. Stroma
- B. Grana
- C. Thylakoid membrane
- D. Intergrana
Explanation
The thylakoid membranes are the sites within chloroplasts where chlorophyll pigments are embedded. These membranes are integral to the light-dependent reactions of photosynthesis, as they house the photosystems that capture and convert light energy into chemical energy. The stroma, while important for the Calvin cycle, does not contain chlorophyll. Grana are stacks of thylakoid membranes, but the chlorophyll is specifically within the membranes themselves. 'Intergrana' is not a recognized term in the context of chloroplast structure.

About Bioenergetics
Cellular respiration explains how cells release energy from glucose through glycolysis, the link reaction, Krebs cycle and electron transport chain. It includes ATP production, substrate-level and oxidative phosphorylation, aerobic versus anaerobic respiration, and the roles of mitochondria, oxygen and fermentation in energy transfer.
