Hi everybody. Here's our next problem. According to Chemie osmotic theory, the transferring of blank down in the electron transport system yields blank through a series of oxidation reduction reactions. We have a little hint here from the words electron transport system because we are talking about the transferring of electrons down an electron transport chain. These are proteins, search proteins embedded in the cell memory. And as the electrons are transferred, they're coming from a higher energy state to a lower with each step. And that releases energy. That energy is then captured in the form of a T. P. And we know that these reactions are redox reactions or oxidation reduction reactions because they involve the transfer of electrons as they are occurring. So according to kenya's monarch theory, the transferring of blank down the electron transport system. Well that would be electrons. So let's look at our answer choices that have that as the first choice and choice B. And choice C. Have electron as the first word. So let's eliminate the ones that don't have electron. Their choice A and choice D are not our answer. And then our second word, we have yields blank through a series of oxidation reduction reactions. While we see that the energy that's released as electrons go down electron transport chain yields a T. P. So that would be found an answer. Choice C. Which is our correct answer and not answer. Choice B. Which offers water as the choice for the second answer. So according to kimmy osmotic theory, the transferring of choice. See electrons down the electron transport system yields a teepee through a series of oxidation reduction reactions. See you in the next video.
