Are there any Carbons lost in glycolysis?
How many energy molecules are produced in glycolysis (Gross)? How many does it take to run glycolysis (Net)?
What is the starting point of glycolysis? The end point?
How would submariners ultimately die if they were trapped and the air scrubbers that add oxygen to the air were defective?
If you did not have glucose in your diet, could you make ATP? Why or why not?
What happens in the muscles of free divers that allows them to dive so deep without oxygen? Does this
happen to you? When?
Would letting oxygen into your vat of fermenting wine spoil the wine? Why?
Why do most organisms use aerobic respiration rather than anaerobic respiration?
Flouride can disrupt the electron transport chain what would happen to you if you had flouride poisoning? Why?
Where does glycolysis take place?
Does Citric Acid Cycle require Oxygen?
How many energy molecules are produced in Citric Acid Cycle?
Where does the Citric Acid Cycle take place?
Does Oxidative Phosporylation require Oxygen?
Where does the Oxidative Phosporylation take place?

Hot or Dry Photosynthesis becomes
difficult O2 wants to bind to RuBP (Calvin Cycle) CAM and C4 pathways are the solution for some plants So there is no C to make G3P or sugars Where does photosynthesis take place?
How does a plant let in CO2?
Is glucose the ultimate product of photosynthesis?
Are there any reactions in photosynthesis that do NOT require light energy?
Is chlorophyll the only pigment present in plants?
Why could it be advantageous to have more than one pigment for photosynthesis?
What type of photosynthetic pigment is responsible for donating electrons in Photosystem I and II?
What molecule is responsible for replacing lost electrons in chlorophyll?
What is the ultimate product of photosynthesis? What can it be used for?
When is CO2 used? Why is this important? Can you use CO2 in a similar way?
What molecule is recycled in the Calvin cycle that allows the cycle to repeat?
What molecule does RuBiSCO have a higher affinity for CO2 or O2? Does the affinity for O2 cause problems for the plant?
How have plants evolved to stop the problem?
Where does most of our O2 come from?
How is it possible for you to create glycogen if you cannot incorporate Carbon from inorganic molecule into your body?
Where does excess carbon come from in our environment? Does this cause problems? Are these problems exacerbated by loss of forests and wilderness? http://en.wikipedia.org/wiki/Leaf stoma (pl. stomata) plant 'noses' for gas exchange Solar energy H2O ATP NADPH CO2 G3P O2 During photosynthesis, plants absorb carbon dioxide and sunlight to create fuel—glucose and other sugars—for building plant structures. This process forms the foundation of the fast (biological) carbon cycle. (Illustration adapted from P.J. Sellers et al., 1992.) This diagram of the fast carbon cycle shows the movement of carbon between land, atmosphere, and oceans. Yellow numbers are natural fluxes, and red are human contributions in gigatons of carbon per year. White numbers indicate stored carbon.
