A 20-year-old woman with sickle cell anemia whose usual hemoglobin concentration is 8 g/dL(80 g/L) develops fever, increased weakness and malaise. The hemoglobin concentration is 4 g/dL{40 g/L) and the reticulocyte count is 0.1 %. The most likely explanation for her clinical picture is:

Amylase becomes denatured at a temperature of 80°c. during an experiment to study the effect of varyingtemperature on enzyme activity, amylase’s reactivity with starch was measured at body temperature (37°c), andthen again at an increased temperature of 42°c. how would this increase in temperature affect the experiment
