The activation of chymotrypsinogen, a zymogen, requires the cleavage of a bond between arg-15 and ile-16, and the subsequent attraction of ile-16 and asp-194. complete parts (a) and (b). a) complete the following reaction for the proteolytic cleavage of arg-15 and ile-16 at ph 7.6. specify the enzyme that catalyzes the reaction and modify the given structure to form the products. add or remove bonds, atoms, and charges, and move atoms as necessary.

Now consider the reaction when 45.0 g naoh have been added. what amount of naoh is this, and what amount of fecl3 can be consumed by it?

Which part of earth’s surface receives the most direct rays from the sun? a) equator b) ocean c) poles d) mountains

Problem page combustion of hydrocarbons such as pentane ( c5 h12 ) produces carbon dioxide, a "greenhouse gas." greenhouse gases in the earth's atmosphere can trap the sun's heat, raising the average temperature of the earth. for this reason there has been a great deal of international discussion about whether to regulate the production of carbon dioxide.(a) write a balanced chemical equation, including physical state symbols, for the combustion of liquid pentane into gaseous carbon dioxide and gaseous water. (b) suppose 0.350 kg of pentane are burned in air at a pressure of exactly 1 atm and a temperature of 20.0 degree c. calculate the volume of carbon dioxide gas that is produced.be sure your answer has the correct number of significant digits.
