Photosynthesis & Cell Respiration Review (TEKS B.11 A)

Put these in order, beginning with photosynthesis:

• Organisms take in C6H12O6 from food & O2 from air

• CO2 & H2O released as waste back to the environment

• Plants take in matter (CO2 & H2O)

• C6H12O6 & O2 molecules are broken down to release ATP

• Using energy from light CO2 & H2O molecules rearrange to form C6H12O6 & O2
