Question

modeling photosynthesis
use the information from the equation and table to answer the question.
6a + 6b → c + 6d
which row accurately represents photosynthesis when substituted into the equation?
a b c d
1 c₆h₁₂o₆ h₂o co₂ o₂
2 h₂o o₂ c₆h₁₂o₆ co₂
3 co₂ h₂o c₆h₁₂o₆ o₂
4 o₂ c₆h₁₂o₆ h₂o co₂
1
2
3
4

Explanation:

Step1: Recall photosynthesis equation

The general equation for photosynthesis is $6CO_2 + 6H_2O
ightarrow C_6H_{12}O_6+6O_2$.

Step2: Match with given format

Comparing with $6A + 6B
ightarrow C + 6D$, we have $A = CO_2$, $B=H_2O$, $C = C_6H_{12}O_6$ and $D = O_2$. This matches row 3 in the table.

Answer:

3
