Module 2 Lab 2 Flashcards
What product is consumed during aerobic respiration?
Oxygen
What is produced during aerobic respiration?
Carbon dioxide
How are the treatments different in aerobic respiration
Different temperatures
How does a microrespirometer work
measures the decrease of volume of the air in its respiration chamber as oxygen is consumed by larva
What is the purpose of the KOH in the microrespirometer?
When in the presence of carbon dioxide it will convert it into a solid; doesn’t as volume to air
How do you expect enzyme activity to change in the different treatments?
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
How do you expect enzyme activity to change in the different treatments?
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
How are the treatments different in photosynthesis experiment
Testing environmental factor, presence of light
How are the treatments different in photosynthesis experiment
Testing environmental factor, presence of light
When light is present, which gas is produced abundantly more?
O2
How does gas production during photosynthesis affect leaf density in an aquatic plant?
Decreases density, enough to cause the leaves to begin to float
What product is consumed during photosynthesis?
Carbon dioxide
What is produced when CO2 dissolves in water, and how does it affect the pH of the water?
Carbonic acid (H2CO3), lowers ph of water by donating protons
If CO2 was removed from water, how would that affect the pH of the water?
Decrease in carbonic acid and increase in PH
