Choose the correct option from the following:
$(i)$ The light reactions of photosynthesis occur in the thylakoid / stroma of the chloroplast.
(ii) The membrane-less organelle is the lysosome / ribosome.

Assertion $:-$ There is not a complete one-to-one overlap between the absorption spectrum of chlorophyll $a$ and the action spectrum of photosynthesis.
Reason $:$ Most of the photosynthesis takes place in the blue and red regions of the spectrum,but some photosynthesis does take place at the other wavelengths of the visible spectrum.

What percentage of usable radiant energy entering a reaction site of photosynthesis is converted to potential energy (in $\%$)?

Provide the differences between:
$(1)$ Light reaction (Light phase) and Dark reaction (Biosynthetic phase)
$(2)$ Mesophyll cells and Bundle sheath cells

$RuBP$ carboxylase,$PEPcase$,pyruvate dehydrogenase,$ATPase$,cytochrome oxidase,hexokinase,lactate dehydrogenase. Select/choose enzymes from the list above which are involved in $(a)$ Photosynthesis $(b)$ Respiration $(c)$ Both in photosynthesis and respiration.

Photophosphorylation differs from oxidative phosphorylation in:
