As humans breathe, oxygen is taken in and carbon dioxide is expelled. This process is frequently called organismal respiration. Cellular respiration is a metabolic pathway that degrades biomolecules like glucose to obtain the energy stored in their chemical bonds. Explain how organismal respiration and cellular respiration are interconnected.As humans breathe, oxygen is taken in and carbon dioxide is expelled.

Why did the beans require pre-soaking for 24 hours before beginning the experiment?

If the "no beans" beaker served as a negative control for this experiment, what was the purpose of including a beaker containing dry beans?

What evidence do you have to prove that cellular respiration occurred in the beans? EXPLAIN!

If beans are composed of plant cells, why was it NOT necessary to include controls to account for the use of carbon dioxide by the photosynthetic pathway for this experiment?

For the aerobic respiration experiment, Jesse started his lab too close to the due date, and did not allow enough time for his pre-soaked beans to incubate in water overnight. Jesse set his beans to soak for only 3 hours before assembling the beakers with bromothymol blue. Which of the following describes Jesse's most likely results?

  • Jesse's soaked beans will not perform any respiration over the 24 hour experimental period.
  • Not all of Jesse's soaked seeds will have begun respiring by the time Jesse begins the experiment, resulting in reduced respiration rates.
  • Having absorbed more water in less time, Jesse's pre-soaked beans will perform respiration at much higher rates.
  • Most of the water absorption occurs during the first few hours, so Jesse's pre-soaked beans should perform respiration at the same rate as beans soaked for 24 hours.
