#### Which of the following equations is the summary of photosynthesis? (a) $6CO_{2} + 12H_{2}O \rightarrow C_{6}H_{12}O_{6} + 6O_{2} + 6H_{2}O$ (b) $6CO_{2} + H_{2}O + Sunlight \rightarrow C_{6}H_{12}O_{6} + O_{2} + 6H_{2}O$ (c) $6CO_{2} + 12H_{2}O + Chlorophyll + Sunlight \rightarrow C_{6}H_{12}O_{6} + 6O_{2}+ 6H_{2}O$ (d) $6CO_{2} + 12H_{2}O + Chlorophyll + Sunlight \rightarrow C_{6}H_{12}O_{6} + 6CO_{2}+ 6H_{2}O$

Ans.(c)
Photosynthesis is a multi-step process that requires sunlight, carbon dioxide, and water as substrates.
