What do we call organisms that use inorganic compounds as electron donors in cellular respiration? phototrophes, heterotrophes, organicrophes or lithotrophs.
00:12
So there's really a big distinction here between c and d.
00:15
Organotrophes use organic compounds as electroners.
00:22
Lithotrophes use inorganic compounds as electrononers.
00:27
So the answer here is d, b, lithotrophes.
00:31
And these are very general terms.
00:33
Phototrophes or heterotrophes will fall under one of these.
00:37
For example, we are heterotrophes and we are a type of organotrope, because we get our electrons from organic compounds, for example, glucose.
00:49
Then there are phototrophes, for example, plants, and they get their energy from light, and they use that to bump electrons up energy levels.
01:01
And so they get their electrons, they can, get them from water, which is inorganic.
01:07
So they often use organotrope methods as well in respiration, but in photosynthesis, they're using water.
01:16
So there are a lot of microorganisms that are lyphotrophs, and they use inorganic compounds in aerobic respiration...
