QUESTION 43 The central receptors in the medulla oblongata adjust the breathing rate in levels response to O 0₂ CO₂ OO 2,3-DPG

question: In a red blood cell entering the left atrium in a human, hyperventilation leads to a decrease in the amount of CO2 bound to hemoglobin but little or no increase in the amount of O2 bound to hemoglobin.   answer should clearly state whether or not the statement is correct and then concisely explain why. the answer should be like more than three but less than 5 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…
