If a mixture of these three substrates was presented to elastase with the concentration of each peptide equal to 0.5 , which would be digested most rapidly? Which most slowly? (Assume enzyme is present in excess

If we take the Kcat / KM ratios, we find that PAPAF would be digested more quickly and PAPAG would be slower.

Explanation:

It is important to highlight that elastase is an enzyme that is not only in humans, to degrade elastic fibers, but is also in microorganisms as a virulence factor for the invasion of tissues in our body in less time and in a more destructive way.

tsd is temerature dependent sex determination.

tsd: it is a type of environmental sex determination in which the temperature experienced during embryonic/ larval development (ambient temperature for development) determine the sex of the offspring.

crocodile displays the tsd where the ambient temperature of the developing egg determines the individual's sex. for example in the american alligator's eggs, incubation at 33 ºc produces mostly males, while incubation at 30 ºc produces mostly females. so if the american alligator's egg will get the ambient temperature (33 degree celcius)during embryonic development from egg, the offspring will be male and same for the female sex determination.

the correct answer, according to e2020, is the second choice there is an occluded front in region a and a cold front in region b.
