Processes Details A. Proton Gradient Formation 1. Protons accumulate in the lumen due to water splitting and electron transport. B. Water Splitting 2. Reduces NADP+ to NADPH + H+ by removing protons from the stroma. C. NADP Reductase Enzyme 3. Creates protons and electrons, which accumulate in the thylakoid lumen. D. Proton Accumulation in Lumen 4. Leads to a decrease in pH and creation of a proton gradient across th
Options
- AA - 1, B - 3, C - 2, D - 4
- BA - 4, B - 1, C - 2, D - 3
- CA - 3, B - 4, C - 1, D - 2
- DA - 2, B - 3, C - 4, D - 1
Correct answer
A. A - 1, B - 3, C - 2, D - 4
Step-by-step solution
A - 1: Proton gradient formation occurs as protons accumulate in the lumen due to water splitting and electron transport. B - 3: Water splitting creates protons and electrons that accumulate in the thylakoid lumen. C - 2: NADP reductase enzyme reduces NADP+ to NADPH + H+ by removing protons from the stroma. D - 4: Proton accumulation in the lumen decreases pH and creates a proton gradient across the thylakoid membrane.
