Answer:
binding regulatory subunits and inducing their release from the catalytic subunits
Explanation:
cAMP molecules diffuse into the cytoplasm where they bind to an allosteric site on a regulatory subunit of a cAMP-dependent protein kinase ( protein kinase A, PKA).
-In its inactive form, PKA is a heterotetramer comprised of two subunits namely, regulatory (R) and two catalytic (C) subunits.
-The regulatory subunits normally inhibit the catalytic activity of the enzyme. cAMP binding causes the dissociation of the regulatory subunits, thereby releasing the active catalytic subunits of PKA.
-cAMP stimulates glucose mobilization by activating a protein kinase that adds a phosphate group onto a specific serine residue of the glycogen phosphorylase polypeptide.
I believe the answer you are looking for is or are marsupials..
Answer: A squirrel climbing up a tree is a way squirrels use kinetic energy to survive. A squirrel colliding with a tree.
Explanation: I know this because the motion of climbing up the tree creates the contact of an object moving over a distance through motion . Therefore energy is lost from the squirrel but that energy is transferred.
Answer:
C. On hilly, mountainous farmland.
Explanation:
[] Terrace farming is where the slope is shifted to create a flat area for growing that also provides the ability to catch water.
[] Contour farming means that the fields suit the natural shape of the slope without changing it.
Both of these farming methods most likely would be found where there are slopes and inclines, the only option providing us with this is "C" which gives us our answer.
Have a nice day!
