What types of signal sequences are likely to be cleaved off and which are not? Explain why this is the case. - Answer Signal sequences that are a series of hydrophobic aa are most likely to be cleaved off because the protein needs to be soluble and secreted in the membrane. Describe the function of the SRP. - Answer It pauses translation and then docks the protein and ribosome to the ER, then translation resumes after it when it releases it. How do multiple transmembrane proteins get i...

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? - ANSWERSIncrease 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 is likel...
