Question

11)which of the following receptors bind to signalling molecules in the cytoplasm ? 12) paracrine signaling occurs QUESTION 11 which of the following receptors bind to signalling molecules in the cytoplasm? ligand-gated ion channels B steroid receptors Rhodopsin D. Tyrosine kinase receptors E. G-protein coupled receptors QUESTION 12 Paracrine signaling occurs A across long distances B within a small volume between near-by cells Cat synapses between neurons. D. A & B E. A B, & C QUESTION 13 A protein kinase Generates CAMP B. Adds phosphate groups to proteins C. Removes phosphate groups from proteins D. Metabolizes CAMP E. Speeds up chemical reactions

Explanation / Answer

Question 11.The correct answer is: B.Steroid receptors

Reason: Steroid hormones are signalling molecules that bind to steroid receptors present either in the cytoplasm or nucleus of the cell.

Question 12.The correct answer is:C.at synapses between neurons.

Reason:Paracrine signalling occurs synapses between nerve cells.

Question 13.The correct answer is : B.Adds phosphate groups to proteins.

Reason: Protein kinase catalyzes the reaction in which phosphate group is transferred from ATP to proteins resulting in phosphorylation of the protein.
