Photosynthesis ...

In addition to the 12 molecules of $$NADPH_2$$ the energy required for the synthesis of one mole of hexose by $$C_3$$ and $$C_4$$ pathway is

The structure known as peroxisome is associated with

The $$C_4$$ plants are photosynthically more efficient than $$C_3$$ plants because

Stroma is the ground matrix of

The chlorophyll absorbs mostly

Plastids are different from mitochondria on the basis of which of the following features?

Which of the following statements correctly describes the light reactions and dark reactions taking place during photosynthesis? 
(i) Light reactions occur in grana thylakoids whereas dark reactions occur in stroma of chloroplasts.
(ii) Light reactions generate ATP and $$\displaystyle NADPH_{2}$$ whereas dark reactions consume ATP and $$\displaystyle NADPH_{2}$$.
(iii) Oxygen is released as a by-product during the light reactions as well as dark reactions.
(iv) Light reactions take place in the presence of light and dark reactions are independent of the products formed during light reactions.

$${CO_2}$$ acceptor during the dark reaction of $${C_3}$$ photosynthesis is 

All of the following are constituents of chlorophyll molecules, except

The energy change in photosynthesis is from
