Q

How does a microrespirometer work

A

measures the decrease of volume of the air in its respiration chamber as oxygen is consumed by larva

Q

What is the purpose of the KOH in the microrespirometer?

A

When in the presence of carbon dioxide it will convert it into a solid; doesn’t as volume to air

Q

How do you expect enzyme activity to change in the different treatments?

A

Measurement of oxygen consumption or carbon dioxide production will effectively reveal the reaction rates of aerobic respiratory enzymes ; in warmer temperature more enzyme activity will be found; the warmer it is the more kinetic energy

Q

What is produced when CO2 dissolves in water, and how does it affect the pH of the water?

A

Carbonic acid (H2CO3), lowers ph of water by donating protons
