CHEM 1005 Midterm Questions and Correct Answers | Latest Update 2024/2025 | 100% Pass Changes in the physiological variables listed below can alter the affinity of hemoglobin for oxygen. Which of the following will lower the affinity of hemoglobin for oxygen? - Answer -Increase in 2,3 bisphosphoglycerate (BPG) A decreased affinity will increase the rate of oxygen delivery to the tissues. This will occur when pH is low, there is an increase in CO2, protons or 2,3 BPG. The other scenario...

CMMB 403 Midterm 1Describe the RTK signal transduction pathway when activated by the FGF ligand FGF ligand dimerizes RTK receptor. Receptor is phorphorylated and attracts adaptor/GEF. GEF begins phosphorylation cascade: GEF to Ras to Raf to Mek to Erk to TF. TF transcribes gene Describe the JAK-STAT pathway when activated by FGF FGF ligand dimerizes RTK. JAK2 proteins cross-phosphorylate. Both JAK2s phosphorylate a STAT5 (which is a cytoplasmic tyrosine kinase). The STAT5s dimerize and tr...

Changes in the physiological variables listed below can alter the affinity of hemoglobin for oxygen. Which of the following will lower the affinity of hemoglobin for oxygen? correct answer: Increase in 2,3 bisphosphoglycerate (BPG) A decreased affinity will increase the rate of oxygen delivery to the tissues. This will occur when pH is low, there is an increase in CO2, protons or 2,3 BPG. The other scenarios (a, c, d) will all increase the affinity for O2. Which of the following proteins ...
