Question

The sodium concentration in a cell is 10 times less than the concentration in the surrounding fluid. How can the cell move sodium out of the cell? (Explain your answer.)
a. passive transport
b. receptor-mediated endocytosis
c. active transport
d. facilitated diffusion

Accepted Answer

Hello everyone and welcome to today's video. So we need to choose the incorrect statement from the below options. Remember that we're looking for the false statement as we solve this problem. So all the answer choices are talking about hyper tonic and hype photonic solutions and their content. So in order to solve this problem we're going to have to visualize what a hypersonic versus a hype atomic solution entails in a hype atomic solution. Remember that we're talking about the outside of the cell. We have very little salutes and a lot of water because we have solid or solids whereas in a hyper tonic solution as we see here which is the outside of the cell we have a lot of salutes and very little water because those salutes are occupying the space of the water. Now let's go over answer choices so that we may begin solving this problem. Beginning by answer choices and be hypothermic solutions have high water and low solute concentrations. If we look at what we wrote here, hypothetic solutions do in fact have low solute and high water concentration. So we're going to be able to cancel these two out. Then we have a high hyper tonic solutions have high solute concentrations as we see here, hyper tonic solutions definitely have very high solid concentrations. So we're going to cancel this out as well. Remember that we're canceling these out because they're correct statements and we're looking for the incorrect one. Then we have answer choice. The hyper tonic solutions have high high water concentrations. Well as we see here these hyper tonic solutions are going to have lower water concentrations. So this is an incorrect answer choice and it is going to be the answer choice that we're looking for. So we will highlight it as a correct answer to this question. I really hope this video helped you and I hope to see you on the next one.
