Photosynthesis & Cellular Respiration Review Answers

1. 6CO2 + 6H2O + light energy (sun) ((( C6H12O6 + 6O2

2. C6H1206 + 6O2 ((( 6CO2 + 6H2O + energy

3. see diagram in notes

4. thylakoid membranes

5. stroma

6. cytoplasm

7. cytoplasm

8. mitochondrion

9. An autotroph uses the energy in sunlight or inorganic substances to make organic compounds.

A heterotroph must eat food (other organisms) to get energy.

10. Glycolysis is the first stage of cellular respiration.

When oxygen is not present, fermentation recycles NAD+, allowing glycolysis to continue.
