Answer: 1. Cyclic AMP(cAMP) concentration increases;
2. cAMP then binds to the two regulatory subunits;
3. A change in the conformation of enzyme results. The autoinhibitory sequences move away from the active site of the catalytic subunits;
4. The catalytic sites are now free to catalyse the various reactions of PKA.
(Note: The question did not list the steps to be placed in the correct order)
Explanation:
The inactive form of Protein Kinase A (PKA) contains two identical sub-units (C) and two identical regulatory sub-units (R). Two auto-inhibitory sequences of the regulatory subunits occupy the catalytic sites of the catalytic subunits. After the reaction of adenylyl cyclase, this inactive form of PKA is activated in the following steps:
1.<em> </em><em>Cyclic AMP</em><em>(</em><em>cAMP</em><em>) concentration increases;</em>
<em>2. </em><em>cAMP</em><em> then binds to the two regulatory subunits;</em>
<em>3. A change in the conformation of enzyme results. The autoinhibitory sequences move away from the active site of the catalytic subunits;</em>
<em>4. The catalytic sites are now free to catalyse the reactions various of </em><em>PKA</em><em> which includes the regulation of glycogen, sugar, and lipid metabolism. </em>
Answer:
It’s probably darker because it may have more minerals than the other soils.
Answer : The energy released by an electron in a mercury atom to produce a photon of this light must be, 
Explanation : Given,
Wavelength = 
conversion used : 
Formula used :
As, 
So, 
where,
= frequency
h = Planck's constant = 
= wavelength = 
c = speed of light = 
Now put all the given values in the above formula, we get:
Therefore, the energy released by an electron in a mercury atom to produce a photon of this light must be,
D. Chemical to thermal and electromagnetic
I think It's a value that depends on another
