(a) | Splitting of the water molecule takes place on the inner side of the membrane. |
(b) | Protons accumulate within the lumen of the thylakoids. |
(c). | The primary acceptor of electrons transfers the electrons to an electron carrier. |
(d) | NADP reductase enzyme is located on the stroma side of the membrane. |
(e) | Protons increase in number in stroma. |

I: | A possible location where this could be happening is in the stroma lamellae. |
II: | While the membrane or lamellae of the grana have both PS I and PS II, the stroma lamellae membranes lack PS II as well as NADP reductase enzyme. |

1. | Sugar beet and Cabbage | 2. | Carrots and Tomatoes |
3. | Wheat and Sugar beet | 4. | Tomatoes and Bell pepper |
I: | Water stress can cause the stomata to close, hence, reducing the carbon dioxide availability. |
II: | Water stress also makes leaves wilt, thus, reducing the surface area of the leaves and their metabolic activity as well. |
