Chapter 6, Problem 10R
NAME IT A prokaryotic cell hitched a ride to Earth on a space shuttle from some unknown planet. The organism is a psychrophile, an obligate halophile, and an obligate aerobe. Based on the characteristics of the microbe, describe the planet.

Flasks A and B contain broth, and are inoculated with an identical number of bacteria that are facultative anaerobes. Flask A contains a triglyceride lipid as the sole nutrient source, and Flask B contains a monosaccharide called fructose as the sole nutrient source. Both flasks are incubated at 30°C with aeration (oxygen is added to the broth). Assume the bacteria are capable of catabolism of both fructose and triglycerides.
Mark all the correct statements pertaining to these cultures.
A. Under anaerobic conditions, cells in flask A will produce more ATP
B. Cells from flask B will produce more carbon dioxide
C. Cells from flask B will produce more ATP
D. Flask A will have the greater cell mass
E. Cells from flask A will produce more ATP
F. Cells from flask A will produce more carbon dioxide
G. Flask B will have the greater cell mass
H. Under anaerobic conditions, cells in flask B will produce more ATP
