dermatitis venenata, enables to form an inflammation on the person’s skin because
of various causes such as mineral substances, chemicals, cosmetic products and
other surfaces that may be of contact to the skin in which it causes the skin
to cause inflammation.
Answer:
The answer is B and D.
Explanation:
PKA ( Protein Kinase A) is an enzyme which becomes active with the presence of cAMP molecules in the cell and the cAMP molecules need to bind to R subunits to become active which happens at a ratio of 1:2.
The example given in the question states that the Ro sububit can bind to 8 molecules of cAMP rather than the conventional 2.
This means that the activation of the Ro subunits is harder than the activation of R subunit because of the requirement of higher cAMP concentrations.
B is correct, full activity of PKA with Ro subunits needs a higher concentration of cAMP.
Because Ro binds to eight units of cAMP, the dynamic range of activity of PKA with Ro is going to be over a wider range of cAMP concentration.
