The method that would help determine whether the bacterium is a chemotroph is:
- Growing the bacterium in a sulfur solution to see if it breaks the inorganic molecules down.
Chemotrophs obtain energy by breaking down inorganic molecules, such as sulfur, to generate ATP. By observing whether the bacterium is capable of breaking down the inorganic molecules in the sulfur solution, one can determine if it is a chemotroph.
Your teacher gives you an unknown bacterium to observe. Select the method that would help you determine whether the bacterium is a chemotroph
growing the bacterium in a sulfur solution to see if it breaks the inorganic molecules down
exposing the bacterium to direct sunlight to see if it converts light to chemical energy
exposing the bacterium to carbon dioxide to see if it fixes carbon
growing the bacterium in an agar tube filled with protein to see if it breaks the organic molecules down
