Photosynthesis v/s Respiration: Organisms, ATP, Fermentation, Enzymes

1. What types of organisms can use Aerobic Cellular Respiration to break down glucose to produce ATP? Provide examples.

2.   What types of organisms can use Photosynthesis to produce glucose? Provide examples.

3. If oxygen is lacking, how might cells meet their energy needs through fermentation? Explain and give some examples of cells that can do this.

4. Both reactions are examples of complex metabolic pathways, consisting of many linked reactions. Briefly, explain the role of enzymes in chemical reactions and metabolic pathways.
