What gas was produced in this process? Carbon dioxide gas
Which set up was the control group? The set up with no sugar
What is the independent variable (what was changed) in this experiment? Presence of sugar
What is dependent variable (what was measured) in this experiment? Production of carbon dioxide gas
Explain how the experiment may have produced data that was incorrect (sources of error) Improper mixing of reactants could have led to less production of carbon dioxide, thus, giving false impression

What waste product of yeast respiration is useful in making beer/wine? Alcohol
Write down the equation for cellular respiration
Glucose + Oxygen Carbon Dioxide + Water + ATP (Energy)
C 6 H 12 O 6 + O 2 CO 2 + H 2 O + ATP
In this equation, what is being reduced and what is being oxidized
Reduced - Oxygen; Oxidized - Carbon
Why do living organisms carry out the process of respiration? Respiration helps absorb oxygen and expel carbon dioxide in animals and vise versa in plants
