What is the function of the cell/plasma membrane?

• It stores genetic information.

• It synthesizes proteins.

• It allows selective traffic of substances into and out of the cell.

What is the balanced chemical equation for aerobic cellular respiration in mitochondria?

• C6H12O6 + 6O2 → 6H2O + 6CO2

• C6H12O6 + 6CO2 → 6H2O + 6O2
