Question

Illuminated isolated chloroplasts release $O_2$ in the absence of $C{O}_2$. Which will increase oxygen output?

• A. $H_{2}O$
• B. $NAD{P}^{+}$
• C. $NA{D}^{+}$
• D. Green light

Answer 1

The correct option is B $NAD{P}^{+}$

The factors that affect photosynthesis are carbon dioxide concentration, oxygen concentration, temperature and pH of the soil.

when the light falls on the PS of chloroplasts, they induce electron movement. An increase in the amount of NADP⁺ results in the splitting of water that takes place in the photosystem II and this release oxygen in cells.

So, as the amount of NADP⁺ increases then the concentration of oxygen also increases.

So, the correct option is ' NADP⁺ '.
