Hi guys. I'm in trouble with these who questions: 1)If a patient breathes air with 5% of O2: - His pCO2 grows (I think it's true but I also think he should iperventilate!) - His Davenport pH curve should go to the left ( T or F ?) - Is blood should be acid (T of F) 2) The fact that air has got such big dielectric constant causes its limitate diffusion through the membrane (Is it true?) Please....I'm having the test this week! Thank you so much

Hi Guys! I'm having some troubles with this exercise! Glutamate is marked in C1 and N with a radioisotope. I have to guess which atoms of the following molecules would me marked: Urea ( to me it should be N1) Succinate (C4? I've considered it as entering the TCA cycle) Arginine (N1?) Citrulline( N1?) Ornitine ???? Aspartate (C1??) Can anyone tell me if I'm right? I've thought Glutamate's as being a part of CarbamateP making all the urea cycle , while I've supposed that the C backbone become aKg. Anyway I fear there's something wrong! Help meee
