- Question 11. // Hint: Isoelectric focusing separates proteins based on their pI values, and can separate proteins that only differ by a net charge of ±1.±1. Recall that an amino acid residue with a negatively charged R group has a relatively low isoelectric point (pI) where it has zero net charge. Likewise, an amino acid residue with a positively charged R group has a relatively high isoelectric point (pI) where it has zero net charge. Order from Low pH to High pHQuestion: 1.

CHEL 114 – Session 11 - Lab Report sheet Khan, Rajpara, Heidary - 8/2020question: Increasing the rate of breathing is a more effective strategy to increase alveolar ventilation than increasing depth of breathing. answer should clearly state whether or not the statement is correct and then concisely explain why. the answer should be like a few sentences and address all of the points in the statement. Here is an example: Both transmembrane carrier proteins and transmembrane channel proteins can mediate active transport of a hydrophilic solute through a cell plasma membrane. This statement is incorrect. Movement of a solute through a channel protein is always passive, whereas carrier-mediated transmembrane transport can be either passive or active. A transmembrane channel protein creates a pore through the membrane allowing for simple diffusion of a hydrophilic solute down a concentration gradient through the membrane. In contrast, transmembrane carrier protein interacts with and 'escorts' a hydrophilic solute through the membrane and is capable of…
