How do I Construct a table to compare the products and reactants in photosynthesis and cellular respiration

katen-ka-za [31]

Explanation:

Create the column headings "Reactants" and "Products". The two row headings should be "Photosynthesis" and "Cellular respiration".

Before filling in the table, make sure you know what the products and reactants from photosynthesis and cellular respiration are.

Remember reactants are the 'before' on the left, and products are the 'after' on the right.

<u>Photosynthesis</u>:

$CO_{2} + H_{2}O+light =>O_{2}+C_{6}H_{12}O_{6}$

<u>Cellular Respiration</u>:

$O_{2}+C_{6}H_{12}O_{6}=>CO_{2} + H_{2}O+ATP$

See attachment for how the table could look.
