Lecture 11 Moving Molecules Reading Assignment and Worksheet

Physiology - question 1 a-c

question: 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…

Question : Ion exchange chromatography (Indicate the right answers) : A- It allows the separation of proteins according to their mass. B- A cation exchange column fixes molecules at a pH being below of their pHi. C- Elution of the proteins follows their increasing size. D- Is constituted by a resin composed of porous beads through which the proteins do transfer more or less fast according to their size. E- An anion exchange column has a negative surface charge.
