g Glucagon is a hormone that is released when the level of glucose in the blood is low. Glucagon uses a G protein signalling pathway to promote glycogenolysis. Put the steps of the signal transduction pathway in order after the release of glucagon into the blood before glycogen phosphorylase is activated leading to glycogenolysis. 1. Glucagon binds extracellularly to G protein-coupled receptor. 2. G protein releases GDP and binds GTP. 3. Activated G protein activates adenylyl cyclase. 4. Adenylate cyclase converts ATP to cAMP. 5. Cyclic AMP activates protein kinase A.

The fish shown above is a tarpon. it is a fast-swimming and powerful open-water fish. its closest relatives, oddly, are burrow-dwelling conger eels that stay on the bottom. both eels and tarpon developed from snake-like larvae that float in the plankton during the first stages of life. once they mature, tarpon and eels are not found near one another in the ocean. the tarpon and the eel illustrate all of the following except

An enzymatic hydrolysis of fructose-1-p, fructose-1-p(aq) + h2o(l) - fructose (aq) + pi (aq) was allowed to proceed to equilibrium at 25°c. the original concentration of fructose-1-p was 0.2 m, but when the system had reached equilibrium, the concentration of fructose-1-p was only 6.52 x 10^-5 m. calculate the equilibrium constant for this reaction and the free energy of hydrolysis of fructose-1-p.
