True or False: Pyruvate’s “haircut and conditioning” occurs after it has been through the citric acid cycle.
False
True or False: Assuming the ideal condition we discussed in class, a glucose molecule will eventually yield 32 net ATP throughout the entire cellular respiration process.
True
True or False: Lactic acid fermentation will occur in the presense of oxygen.
False
Which of the following is NOT a photoautotroph A. Algae B. Cyanobacteria C. Fungi D. Flowering herbs like thyme and basil

B
Why are (most) plants green?
A. Chlorophylls A and B reflect green light
B. Chlorophylls A and B absorb green light as the source of energy for photosynthesis

D. All photosynthetic pigments are colored green
A
True or False: The carbon atoms used to construct sugars during the Calvin Cycle originally come from CO2.
True
True or False: Rubisco, the enzyme responsible for the fixation of carbon into its organic form during the Calvin Cycle, functions optimally in aerobic (oxygen-rich) conditions.
