Chapter 2.15, Problem 1MQ
Summary Introduction
Some Archaea and Bacteria are planktonic and possess the ability to float in the water with the help of gas vesicles. Gas vesicles provide buoyancy to aquatic microbes and allow the microbes to locate themselves in the region suitable for their

Extension Questions
Which of the following sequences correctly represents the flow of electrons during
photosynthesis?
A) NADPH 02 → CO2
B) H₂O
NADPH →Calvin cycle
C) NADPH chlorophyll →Calvin cycle
D) H2O
E) NADPH
photosystem I → photosystem II
electron transport chain → 02
Place these events in the correct order: absorption of electromagnetic radiation by chlorophyll,
synthesis of sugars, utilization of carbon dioxide by Calvin cycle enzymes, synthesis of
NADPH, synthesis of ATP, conversion of water into molecular oxygen.
Is NADP+ oxidized or reduced during the light reactions? How do you know this?
What would you expect to happen if you inactivated the NADP+ reductase?

- CHCASE Dashboard A student conducts two experiments to observe the effects of different factors on ATP production during aerobic cellular respiration. In the first experiment, the student isolates mitochondria in a test tube, adds oxygen to the test tube, and measures the amounts of ATP produced at three temperatures. In a second experiment, the student keeps the temperature the same and varies the concentration of oxygen added to the test tube for each trial, The student records all data in the table shown.

Both Photosynthesis and respiration rely on electron transport. Although there are many differences, what do these electron transport chains have in common? In both, the electron donor (water in the case of photosynthesis, NADH in the case of respiration) is a strong reducing agent In both, the proteins which shuttle the electrons (Plastoquinone in photosynthesis, Ubiquinone in the case of respiration) are oxidized and reduced In both, electrons move spontaneously from high to low redox potential. In both, chemiosmosis results in the production of ATP A. 1,2 and 3 B. 1 and 3 C. 2 and 4 D. 4 only E. All of 1, 2, 3 and 4 are correctarrow_forwardNeed help with #6 and 5 pleasearrow_forward
