The entire process of photosynthesis consists of a number of reactions. Where in the cell do each of these take place? Synthesis of $ATP$ and $NADPH$ occurs in/at:

The first electron acceptor from an excited chlorophyll molecule of Photosystem-$II$ is .......

When a chlorophyll $a$ molecule loses $1$ electron from its outer orbit,what does it gain?

The following $(I-VI)$ are the main steps of chemiosmotic $ATP$ synthesis in the light reaction. Arrange them in the correct order:
$I$. $H^+$ concentration gradient established
$II$. $H^+$ diffuses through $ATP$ synthase
$III$. Carriers use energy from electrons to move $H^+$ across the membrane
$IV$. Electrons from $PS-II$ pass along the electron transport chain
$V$. Light excites electrons in $PS-II$
$VI$. Energy of $H^+$ flow is used by $ATP$ synthase to make $ATP$

How many total water molecules are required by green plants to reduce $6$ molecules of $CO_2$ into a hexose sugar?

The primary electron acceptor for the electron released by $P_{680}$ in the light reaction is ......... .
