- Please help me with this question. More than one answer may be correct. THe graph relating to the information is included below. The above figures show the rate of actin polymerization in the presence of various concentration of profilin (Pfn). In the top figure, flourescence intensity is a measure of total actin that has been polymerized, and this is plotted versus time in seconds. The shade of blue of the lines in the top figure correspond to the shaded blue bars representing various concentrations of profilin in the lower figure. The lower graph shows the initial rates of polymerization of actin plotted again concentration. Which of the following is true: Question 21 options: profilin in a molecular motor profilin is a promoter of actin polymerization profilin replaced G-actin in an F-actin strand and breaks the filament profilin is an inhibitor of actin polymerization profilin binds to G-actin, preventing it from polymerizingarrow_forwardPlease answer fastarrow_forwardOtto Warburg and his coworkers first described “aerobic glycolysis”, which has come to be known as the Warburg effect.

Salmoneus, who is 60 years old, agrees to deliver Callisto to face charges for war crimes. On the way, their cart crashes down a ravine. Salmoneus dies. When a cell dies its plasma membrane becomes “leaky”; i.e., it becomes permeable to ions that were unable to freely cross the membrane during life. Thus, after death, calcium ions leak across the sarcolemma of muscle fibers. This calcium leak causes rigor mortis, a temporary stiffness of the muscles after death. Apply your understanding of the mechanism of skeletal muscle contraction (specifically regarding events within muscle fibre) and explain the molecular basis of the phenomenon known as rigor mortis.arrow_forward
- What sort of cellular changes would you expect a sailor sick with scurvy to experience? O Their collagen (an extracellular matrix component) would be diminished, resulting in fewer binding sites for integrins. The end result would be less adherent cells. O Their collagen (a cytoskeletal fiber) would be diminished, resulting in a loss of contractile motion within the cell, affecting both cell migration and muscle function.arrow_forwardpQLScB3CBS-8U2yQp5UAPJA-R3spS6YB8srqTGBoSwdXc_EattnA/viewform dvisor Main...
