Glucose, O2

CO2, O2

ATP, O2

6.Products of photosynthesis are

CO2; H2O; ATP

Glucose; O2; H2O

CO2; ATP

Explanation / Answer

1. Is gas exchange…produces ATP

2. The two sources of energy that power life on earth are Solar energy and Geothermal energy.

3. Fermentation is necessary in cells that do not have access to oxygen because fermentation leads to the production of NAD+, which is required for the continuation of glycolysis. Glycolysis leads to the production of ATP.

4. The NADH and FADH2 produced during Krebs cycle are used in oxidative pgosphorylation for the production of more ATP. For every NADH molecule, that enters the electron transport chain, 3 ATP are produced. For every FADH2 molecule that enters the lectron transport chain, 2 ATP are produced.

5. CO2, H2O, ATP

6. Glucose; O2; H2O
