a. The building of starch from glucose, active transport of ions across the membranes of cells, and production of sugars in the Calvin cycle b. 0.25ml c. 0.016 ml/min d. 5. Answer the following questions. a) Describe the relationship between temperature and consumption of oxygen. The amount of oxygen consumed by germinating corn at 22°C is approximately twice the amount of oxygen consumed by germinating corn at 12°C. b) Calculate the rate of oxygen consumption for germinating corn at 12 degrees. (Show calculations) Answer: 0.04 ml/min (0.4 ml − 0 ml = 0.4) x (10 minutes − 0 minutes = 10 minutes). 0.4 ml/10 minutes = 0.04 ml/min.
c) Based on the graph, would you conclude that non germinating seeds respire? Yes, the rate is slow but it still respirates. Extension The following lab was conducted using respirometers to measure change in pressure inside a pipette for non- germinating seeds, germinating seeds, and mealworms. The following data was gathered: Data Table 2: Calculation of Oxygen Consumption Respirometer 1a- Room Temperature, Non-Germinating Seeds Time Interval (min) 0 min 5 min 10 min 15 min 20 min Reading (ml) 0.82 0.82 0.81 0.80 0.79 Δ volume (ml) (reading – time) N/A 0 0.01 0.02 0.03 Respirometer 1b- Room Temperature, Germinating Seeds Reading (ml) 0.87 0.76 0.61 0.50 0.35

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
