- Flippases help maintain membrane asymmetry. True FalseLigand binding and response. The following question involves the ligand binding to a receptor and the receptor's response to that ligand. What ligand concentration would be required for a full agonist with a KD of 8 nM to achieve a response of 0.75?role of iron (Fe) in human body by focusing on Structure-Function-Location• how much of FE is present in your body? • what does it do? • where is it found? how long can you survive these conditions, before you will manifest first signs of physiological/psychological (either one, maybe both?) pathology? What will be those symptoms? Can you tell what is the natural cycle of Fe in your body?
- The biochemical pathway impacted by your disease Congential Adrenal Hyperplasia that shows the name of each enzyme/protein in the pathway.True and false - A k+ channel will be just as permeable to Na+ as to K+ because Na+ is a smaller ion - channel proteins are for small things like ions, not larger molecules like sugars - channel proteins have specificity by providing amino acid side chains to H bongs with particular ions in place of those ions binding with water -Ion channels all low ions to pass through in either direction depending on the electrochemical gradient of the ion - the free energy of an ion travelling across the plasma membrane depends completely on the ions concentration inside versus outside the cellstructure of cholesterol, define the three regions of the molecule, know that this molecule regulates membrane fluidity, and distinguish between esterified and unesterifiedcholesterol
- Need help The β chains of HbA and HbS were treated with trypsin, and the sequence of the N-terminal tryptic peptides are as given below. Do these peptides separate from each other in an electric field if the pH is 7.0? Explain in detail the reasoning behind your answer and include your calculations for the charge of each peptide in your answer. HbA: Val-His-Leu-Thr-Pro-Glu-Glu-Lys HbS: Val-His-Leu-Thr1H. please help me in detail. For molecular Mechanism of ATP versus GTP selectivity of adenylate kinaseThe equilibrium potential for a given ion (Eion) is a theoretical value. For a given concentration gradient of an ion, the equilibrium potential is the charge inside the cell required to hold an ion at that concentration. That is, it is the charge required to perfectly oppose the drive of the ion to move down its concentration gradient. So, if the concentration of Nat is higher outside the cell than inside, its equilibrium potential (ENa) must be I and if we add more sodium to the extracellular fluid, then ENa will II.
- Disadvantages of cholesterolresting state of the protein, the Lys 216 Schiff base has pKa = 9.5 and Asp 85 has pKa = 3.5. When the conformational change occurs, the proton that was on the Schiff base moves to Asp 85. This should tell you that one or both of these two pKas changed with the conformational change. How does the pKa of Asp 85 compare with the pKa of the Lys 216 Schiff base after the conformational change?Predicting how variation in membrane lipid composition will affect the fluidity and mobility of integral membrane proteins
