Based upon the information in the passage, the renal clearance of glucose in a healthy adult is most likely:

A. 0 ml/min

B. 60 ml/min

C. 125 ml/min

D. 145 ml/min

I picked C because that was the only information they gave in the passage regarding this, yet the explanation is that All glucose is reabsorbed in a healthy adult and you should know this. WTF? The question specifically said look to the passage for this answer. Is this not misguiding? Is the actual MCAT anything like this in its misdirection and trickery?

I thought that was an especially sinister question as well. Don't worry, the MCAT won't be THAT tricky. It'll just be a little tricky (don't really know how to quantify this).

Haha thanks for the reply! I guess I was just looking for some agreement. I've taken AAMCs recently, so now I know this is not the case at all!! lol actually quite easy.

Hey btw I'm a big fan of yours and your MCAT improvement! I saw your post in 30+ habits using just EK. It would be cool if you could PM me what you did in the final stretches to get such a score--as Ive got my exam coming up and have similar preparation! Ive been using EK and I just have a few more in class exams to finish but finished content review otherwise. But Ive scored 11/9/10 AAMC3 and 12/8/12 AAMC 4...most trouble with verbal :/

I felt EK exams are definitely more sinister than the MCAT. Although there are VR questions....hah

Ah not really helping but as a quick guess i chose A too... but my reasoning is twisted in outside knowledge. Diabetes Mellitus = sweet urine, thats how they used to test for it, by tasting the urine (jeez, i just made this thread sick huh?). If we lost glucose in the urine as healthy adults it would be a little difficult then in the olden days to test for diabetes mellitus...

Yeah... I know, weird. The way I see it, Bio = VR that you're supposed to bring outside knowledge in to eliminate/select answer choices.

I stopped using EK 30 min exams because 85 percent of questions can be solved with outside knowledge. That's not how the MCAT is tested. TBR passages Reflects the style of MCAT passages better.

Not sure how this pertains the passage. I'm not a big fan of EK's 30 minute exams. I don't think they are any indication of what the MCAT is like. I think it's pretty important though to realize that in a healthy individual, 100% of glucose is reabsorbed. TPRH and EK, I recall both mentioned that. Glucose is essential nutrient as it is the primary molecule responsible for the production of ATP. Most of the glucose, along with amino acids and other essential nutrients are absorbed in the proximal convoluted tubule. As the above person mentioned, the only time we lose glucose in our blood stream is if our blood glucose is too high. Normally after a sugar heavy meal, our body releases insulin to uptake glucose and store it as polymer glycogen. In diabetes, insulin receptors or the insulin hormone is defective so glucose isn't actively absorbed from our blood stream. As a result, glucose levels in the blood become extremely high. This damages many areas of the body including our nervous system among other organs. In the nephrons of the kidney, Glucose/Sodium pumps become saturated so some of the glucose leaves the body as urine. It might be helpful to know that most reabsorption occurs in the proximal convoluted tubule of the nephron. If you're interested in learning more about this, check out the excretory system section in EK or TPRH. I think both do a really good job of explaining this process. Hope this helps!

I stopped doing them for this reason too. I can get by the typos, but the poor explanations and the ridiculous (unrealistic) questions became too much.

I'll do them during my last week for quick recall purposes, but won't lose sleep over anything I miss or disagree with.
