During photosynthesis,energy is transferred from the light reaction to the dark reaction in the form of .........

The separation of water into hydrogen and oxygen during photosynthesis is aided by

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?

Which step of non-cyclic photophosphorylation is inhibited by $DCMU$?

The synthesis of $ATP$ during photosynthesis is called:
