AP Biology

I'm doing an AP Lab on Cellular Respiration that is Ward's AP Biology Lab 5 with the germinating and non-germinating peas.

One question asks what is the purpose of KOH in this experiment? I wrote Potassium Hydroxide is used to remove the CO2 produced during cellular respiration. How does KOH remove CO2?

Another question asks lists 3 controls in this experiment. I put down temperature, type of peas. I need another one. I think it somewhat deals with the respirometer.

I'm stuck on this question:
During aerobic respiration, glucose is broken down to form several end products. Which end products contain the carbon atoms from glucose? The hydrogen atoms from glucose? The oxygen atoms from glucose? The energy stored in the glucose molecules?

If anyone is familiar with this lab, can I get some help? Thank you!

  1. 3. the end products are 6 CO2 and 6 H2O, otherwise known as carbon dioxide and water.
    the carbon dioxide contains the carbon and 2/3 of the oxygen, and the water contains the hydrogen and the 1/3 of the oxygen. don't forget that during aerobic respiration for every glucose molecule six molecules of oxygen (O2) are broken down along with the glucose, which accounts for 12 of the 18 oxygen atoms

  2. The answer preceding mine is correct except that it forgot about the energy. The energy goes into the 36 ATP produced by cellular respiration. By the way I am also currently doing this lab and the preceding answer just saved me.

  3. The other control was the beads that you used to fill the vial upto the same amount when the water was in the gradulated cylinder

  4. yes, the beads are the final control, and I'm doing a write-up on the exact same lab... and how the KOH removes the O2 is still a mystery...

  6. KOH doesn't get rid of the CO2 it simply combines with it to form a precipitate.

  7. The KOH absorbed the carbon dioxide and caused it to form a precipitate at the bottom of the vial.

  9. CO2 contains the carbon atoms from glucose
    H2O " " hydrogen atoms " "
    CO2 + H2O both contains the oxygen atoms from glucose.
    Energy is converted to ATP
