- Question- Some of the reactions of NO in the blood do not cause problems at low concentrations but can upset the normal reactions of hemoglobin if there is a large concentration of NO. The same reactions can cause trouble if a synthetic blood substitute contains a molecule similar to hemoglobin but does not contain all the other enzymes normally contained in red blood cells. Explain what this problem is and how it arises.Cells and Membranes a. Give two examples of molecules that can pass through cell membranes without the need for energy, why can they do so?Recall from your BI110 class that metabolically active tissues produce CO2 as a by-product of cellular respiration. Those metabolically active tissues require the O2 that is brought by hemoglobin for the same process (cellular respiration). Explain why the effect of pH on hemoglobin’s affinity for oxygen is consistent with delivering it to actively metabolizing tissues. (Hint: think about what effect the presence of CO2 has on the tissues…)
- (No more than one page). Explain why quaternary structure is necessary for cooperativity and allosteric regulation. Use hemoglobin as an example. Include the various allosteric effectors that influence oxygen binding."Hemoglobin can be in either an oxy- or deoxy- state at a given pH. Given the appropriate pKa values, calculate fraction protonated at a given pH" How would I do this?they said that oxygen radicals are reactive, and unsaturated fatty acids are reactive too. does it mean that unsaturated fatty acids are considered radicals? yes or no? please explain
- they said that oxygen radicals are reactive, and unsaturated fatty acids are reactive too. does it mean that unsaturated fatty acids are considered radicals? is it true or false? please explainCells and Membranes b. Give two examples of molecules that require energy to pass through cell membranes, why do they need energy to do so?they said that oxygen radicals are reactive, and unsaturated fatty acids are reactive too. does it mean that unsaturated fatty acids are considered radicals? this statement is false, state a counterargument
