The statements that correspond to cellular respiration are:
2) CO2 diffuses passively out of the cell.
6) O2 is pumped in and forces CO2 out
Cellular respiration in animals produces carbon dioxide as waste products. Cellular respiration is presented like this:
oxygen + glucose → energy + carbon dioxide + water
Conduction: I would explain why I think so, but I think the answer itself explains why well enough so that I don't exactly have anything to add
