Compare optimal temperature and optimal ph for catalase to the physiological conditions of a cell.

The optimal temperature for catalase to the physiological conditions of a cell is 37 degree Celsius. The optimal pH for the enzyme is neutral, that is, 7.0. Catalase is generally used by the majority of animals to catalyze hydrogen peroxide into water and oxygen.  

Hydrogen peroxide is one of the harmful byproducts of certain kind of metabolic procedures and must be transformed quickly post creation to inhibit damage.  

1. a host loses nutrients to a parasite

2. a parasite only benefits when the host is alive (cause if the host dies the parasite dies with it )

3. producers to consumers

4. the tapeworm is a parasite

5. they convert energy from the sun (photosynthesis)

6. sunflower-robin (i think im 80% sure)

7. producer

8. consumer

9. prey

10. fresh water snails ( cause the green algea is the producer and the snails are the primary consumers and the small fish consumer so is the big fish)
