which is true? group of answer choices a) protein kinase phosphorylation can result in stimulation or inhibition of the activity of effector proteins b) ca2 and cyclic amp are second messengers c) phosphodiesterase converts gmp into cgmp d) both a and b are correct e) all choices are correct



Answer :

Both a and b are correct that is protein kinase phosphorylation can result in stimulation or inhibition of the activity of effector proteins and ca2 and cyclic amp are second messengers.

What are second messengers and protein kinase phosphorylation?

  1. Secondary messengers are the molecules inside the cell that transmit from a receptor to target.
  2. Some of the secondary messengers are cyclic nucleotides a class of secondary messengers.
  3. Cyclic GMP and calcium are also the secondary messengers along with cyclic nucleotides.
  4. Protein kinase phosphorylation , in which protein kinase is an enzyme that modifies molecules mostly proteins by chemically adding phosphate groups to them.
