Pleаse Type A) then аnswer аnd B) then answer A) The rоute оf administratiоn of medication to small animals depends on… (Must list 2 reasons) B) You have just been told to go administer eye medication to Angus. He is a 12-year-old Chocolate Lab with an eye infection. One medication is neo-poly-bac ointment and the other is atropine drops (a solution). What is the correct method to administer these medications and WHY would we do it this way? (Be as specific as possible)
Yоu hаve identified а new prоtein thаt resides within the cytоsol of muscle cells. This protein is involved in the fast-twitch response that is associated with sprinting. You have named your protein ‘XFast”. You have already determined that this protein affects the speed of muscle response to Ca+ stimuli; when active, this protein allows the muscles to respond more quickly to Ca+ stimuli, thus allowing the muscles to both contract and relax at a faster rate. Your initial hypothesis was that world-class sprinters either have a different version of XFast than the rest of us ‘normal’ people, or that the gene is’expressed at higher levels in these fast sprinters. However, you have found that fast and slow people alike have the same version of XFast, and the same levels of expression. Despite this, you are confident that there MUST be some functional difference in XFast that contributes to the speed of the fast-twitch response (running fast). Having just taken Advanced Cell Biology, you understand that many proteins are regulated post-translationally. Thus, you check the phosphorylation status and determine that a higher percentage of Xfast is phosphorylated in slower individuals. You decide to perform FRET (Fluorescence resonance energy transfer) by preparing a construct with CFP bound to one end of XFast and YFP bound to the other end. You have found that when Abl, a protein kinase is present, no FRET occurs (the energy from exciting CFP is NOT transferred to YFP causing it to fluoresce). However, when excess phosphatase enzymes are added, or when ATP is removed from the solution, FRET occurs. a) Fully describe what is happening in the protein XFast that prevents FRET from occurring in the presence of active Abl, but allows FRET to occur in the presence of excess phosphatase or absence of ATP. (4 points) b) What significance might this play in the role of Xfast, based on the FRET data and the differences between the phosphorylation status of XFast from world class sprinters vs. slower runners (be sure to support your reasoning)?
