Biology Review for Cellular Respiration Test

Review for Cellular Respiration and Photosynthesis Test

1.  Why do we begin this section of the course with a detailed look at:

a.  Cellular structures; especially cell membrane

b.  Enzyme function

c.  Energy molecules in the cell

2.  Be able to label the diagram of cell membrane, and describe structure/functions of major membrane components.

3.  Be able to distinguish between passive and active transport. Name and describe the different examples of each.

4.  What do we know about enzymes? What makes them specific? Sensitive? How can they be regulated? What energy molecules did we discuss and why?

5.  Record the NET equation for cell respiration. Why do we use net equations? How are these deceiving?

6.  List, in order, the four main stages of cell respiration. What are the KEY things that happen in each stage? Where does this take place? How are the three stages connected? (What molecule links one stage to the next?)

7.  Be able to label the diagrams of the four stages of cell respiration. (Fill in the blanks on the diagrams.)

8.  HOW do all the molecular conversions take place? (What molecular “hands” do all the work of converting one molecule into the next?)

9.  How many ATP are produced from ONE glucose molecule? What does ATP stand for?

10. Please be able to write the equation for the formation of ATP. Is this endo or exothermic? How is the phosphate attached? (name for the process)

11. What happens in the cell under anaerobic conditions? (What does anaerobic mean?)

12. What are the two KEY products in Krebs’ cycle? Which one is a waste product? Which one is useful? Why?

13. What does REDUCED mean (in chemistry terms). When we talk about reduced coenzymes…what does this mean??

14. What do these reduced coenzymes do?

15. Please be able to describe the key events of stage III in words! Try it!

16. Do you die without glucose? Why or why not? How does the glucose get to the cell?

17. Why do you die without oxygen? What actually happens if O2 is not present?

18. How does oxygen become water?

19. Why do we need to breathe ALL the time, but can go days without eating?

20. Record the net equation of cellular respiration; list which body systems are responsible for shuttling these components into and out of the cell. During which phase of cell respiration is each reactant or product used up or produced?

21. Explain how photosynthesis is in many ways a mirror image of cell respiration. What are some exceptions to the “mirror image” idea?

22. This looks a lot like God had the original idea behind “reduce, reuse, recycle”! Explain!

23. Be able to LIST the stages of photosynthesis in order and provide a description of the MAJOR events in each stage. (nice summary diagram on pg 147)

24. Why are leaves green? What other pigments are involved in photosynthesis?

25. Know the parts of a chlorophyll molecule. What role does chlorophyll play in the light reaction? How is chlorophyll “regenerated”?

26. How do we know that leaves must be translucent?

27. What is a stoma and why do plants need to regulate stomatal opening/closure?

28. Why do plants die without water?

29. What adaptations have plants that live in hot, dry climates made?

30. Review your notes and diagrams. You are responsible for all material taught and assigned from your textbook as well.
