Video transcript

Hello, everyone and welcome to today's video. So which of the following is not reabsorbed by the proximal convoluted tubule of A ne as the answer choice A we have sodium and pota as answer choice B we have H2O or water C. We have glucose and D we have penicillin. Well, remember from previous videos that most of the reabsorption that we're going to see in the body is going to happen in the, in the kidneys and most of it is also going to happen in the proximal convoluted tubule within this neph. Now, there are going to be several substances that are reabsorbed here. Some examples are going to be sodium ions or N A plus. We're going to have virtually all nutrients, things like glucose, amino acids, vitamins, and even some other ions. We're going to have water, we're going to have lipid soluble, so solutes. And finally, we're going to have some urea. Now, these are all the substances or the most popular ones that are going to be reabsorbed in the proximal convoluted tubule. Looking at our answer choices, the only substance that's not present here is going to be the, which is penicillin Now penicillin remember is an antibiotic and it's not going to be reabsorbed, it's going to be secreted completely. So we're going to be letting go of it. Therefore, we can highlight answer choice the penicillin as a final answer to our question. I really hope this video helped you and I hope to see you on the next one.
