Question

Use the information from the equation and table to answer the question.

6A + 6B → C + 6D

A 5-column table with 4 rows. Column 1 is unlabeled with entries 1, 2, 3, 4. Column 2 is labeled A with entries C 6 H 12 O 6, H 2 O, C O 2, O 2. Column 3 is labeled B with entries H 2 O, O 2, H 2 O, C 6 H 12 O 6. Column 4 is labeled C with entries C O 2, C 6 H 12 O 6, C 6 H 12 O 6, H 2 O. Column 5 is labeled D with entries O 2, C O 2, O 2, C O 2.

Which row accurately represents photosynthesis when substituted into the equation?

1
2
3
4

Answer 1

3

Because photosynthesis is 6 CO2 + 6 H2O → C6H12O6 + 6 O2, which corresponds to A = CO2, B = H2O, C = C6H12O6, D = O2 (row 3).
