Wood frogs freeze solid during the winter and then thaw in the spring. As the freezing progresses, blood circulation stops. How would you expect cells not being served by the circulatory system to produce ATP during this time, and what by-product would you expect to build up in the cells?

On the basis of the calibration of a Sephadex G-200 column with protein standards of known molecular weights, you estimate the apparent molecular weight of a new protein you have isolated from Drosophila mutants revealing accelerated neurodegeneration to be 68 kDa (or 68,000 g/mol). However, when you subject the same protein to SDS-PAGE, the size […]
