Answer:

The statement is false.

Explanation:

Passive transport moves molecules from one side of the membrane to the other with the energy of the chemical gradient (or concentration gradient). Otherwise, active transport uses the hydrolyzation of ATP to gain energy in order to move molecules across the membrane without taking into account the gradient.

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.
