NEETBotanyPhotosynthesis in Higher Plants
Component of Chloroplast Function A. Grana 1. Site of ATP and NADPH synthesis. B. Stroma Lamellae 2. Connects grana and facilitates the transport of molecules. C. Stroma 3. Site of enzymatic reactions that synthesize sugar from ATP and NADPH. D. Light Reactions 4. Light-driven reactions producing ATP and NADPH.
Options
- AA - 4, B - 2, C - 1, D - 3
- BA - 3, B - 1, C - 4, D - 2
- CA - 2, B - 3, C - 1, D - 4
- DA - 4, B - 2, C - 3, D - 1
Correct answer
D. A - 4, B - 2, C - 3, D - 1
Step-by-step solution
A - 4: Grana are the sites where light reactions occur, involving the synthesis of ATP and NADPH. B - 2: Stroma lamellae connect the grana and facilitate the transport of molecules between them. C - 3: The stroma is where the dark reactions (carbon reactions) occur, using ATP and NADPH to synthesize sugars. D - 1: Light reactions are driven by light and produce ATP and NADPH.
