In Botany class, teacher explains, Synthesis of one glucose requires 30 ATPs in `C_(4)` plants and only 18ATPs in `C_(3)` plants. The same teacher explains `C_(4)` plants are more advantageous than `C_(3)` plants. Can you identify the reason for this cont

Explanation

`C_4` plants requires 30 ATPs and 12 DPH `+H^+` to synthesize one glucose, but `C_3` plants require only 18 ATPs and 12 DPH + `H^+` to synthesize one glucose molecule. If then, how can you say `C_4` plants are more advantageous?
`C_4` plants are more advantageous than `C_3` plants because `C_4` photosynthesis is advantages over `C_3` plant, because `C_4` photosynthesis avoids photorespiration and is thus potentially more efficient than `C_3` plants. Due to the absence of photorespiration, carbon di oxide compensation point for `C_4` is lower than that of `C_3` plants.
