Question

The text claims that the evolution of an oxygen-rich atmosphere paved the way for increasingly efficient cellular respiration and higher growth rates in organisms. Explain.

Accepted Answer

Hi everyone. Here's our next question. The process by which a cell utilizes oxygen to produce a maximum of usable energy is termed as well. Let's look to our answer choices. Choice A says photosynthesis. Well, photosynthesis um is not where the cells utilizing oxygen to produce energy and photosynthesis. The plant cells obviously utilizing energy from sunlight to synthesize sugar molecules. So kind of the reverse process, Choice B says cellular respiration. Well, this is our answer to this question. Again, we can if we want a little trick to help remember that. For a test, you think of respiration? You think of breathing? So cellular respiration is that process of using the oxygen we breathe in to produce energy. So I see a cellular oxidation, oxidation is part of respiration. Um as we recall, we transfer electron from one compound to another uh in a process of oxidation. Were oxidizing the glucose molecule during respiration. Um So it's part of the process but it's more of a generic term um anytime you're transferring electrons from one compound to another. And so therefore it's not the description of what's using oxygen to produce energy. So part of the process, but not our answer here. And choice D homeostasis. Homeostasis is that reference to maintaining equilibrium. So we want living organisms need to maintain homeostasis that constant state of the conditions in their cell. So maintaining equilibrium. So not our answer choice here. So again, the process by which a cell utilizes oxygen to produce a maximum usable energy is choice be cellular respiration. See you in the next video
