Q. Select the correct pathway for electron transport during photosynthesis
A) $CO_{2} \rightarrow RUBP \rightarrow$ Glucose- ATP
B) $H_{2}O \rightarrow PS$-$I \rightarrow PS$-$II \rightarrow NADPH \rightarrow H^{+}$
C) $H_{2}O \rightarrow PS$-$II \rightarrow PS$-$I \rightarrow NADPH \rightarrow H^{+}$
D) $H_{2}O \rightarrow PS$-$II \rightarrow PS$-$I \rightarrow$ ATP
Explanation
Electrons during photosynthesis goes from the $H_{2}O$ to the PS-II then by various cytochrome carrier. It reaches to PS-I then reaches to the $NADP^{+}$ and reduces it in the presence of $H^{+}$ to form $NADPH + H^{+}$
