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

- Q1) For primary producers such as plants, photosynthesis requires carbon dioxide (CO2), water (H2O), and sunlight. As a result of photosynthesis, plants produce glucose (C6H12O6) and oxygen (O2). The CO2 is used to make glucose. Energy from sunlight is used to power the reaction that creates the glucose molecules. The data set below is the results of a study that investigated how light intensity (distance from a light source; cm) affects photosynthesis (bubble production; #O2 bubbles) in Elodea (aquatic plant). # of bubbles produced @ 5 cm # of bubbles produced @ 10 cm # of bubbles produced @ 20 cm # of bubbles produced @ 30 cm Group 1 0 9 7 0 Group 2 2 12 6 3 Group 3 2 9 9 2 Group 4 0 8 10 0 Group 5 1 10 7 5 Group 6 3 13 4 4 Group 7 3 10 8 4 Please identify the independent variable and the dependent variable in this study.

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.
