Variable Review

• Dependen (DV): the variable that is measured in an experiement. DRY: dependent, results, Y-axis

  
  

• Independent (IV): the variable that changes in an experiment. MIX: manipulated (means changed), independent, X-axis

Multiple Choice

STAMP

The experiment was set up in three bottles. The first bottle had only yeast and water. The second bottle had only sugar and water. The third bottle had all three. 

To collect our results we measured how big the balloon got which meant the amount of gas that was produced. 

STAMP continued...

Cell respiration occurred in the third bottle because the balloon inflated. The balloon in the other trials did not inflate, which meant that no cell respiration occurred. 

These results make sense because in the third bottle there was the yeast and the reactant it needed for cell respiration which was the glucose. In this bottle when cell respiration occurred, it produced carbon dioxide which caused the balloon to fill up.

Multiple Choice

What does metabolism mean?

• Converting energy into food

• Making light reactions happen

• Converting food into energy

• Burning off fat

Multiple Choice

What is the correct equation for cellular respiration?

• 6O₂ + C₆H₁₂O₆ -> 6CO₂ + 6H₂O + Energy

• 6O₂ + C₆H₁₂O₆ + Energy -> 6CO₂ + 6H₂O

• 6CO₂ + 6H₂O -> 6O₂ + C₆H₁₂O₆ + Energy

• 6CO₂ + 6H₂O + Energy -> 6O₂ + C₆H₁₂O₆

Multiple Choice

ATP is called a cell's "energy currency" because

• ATP catalyzes all metabolic reactions
• ATP allow one organelle to be exchanged for another between cells
• glucose is made of ATP
• most of the energy that drives metabolism is supplied by ATP
