Question
NSULIN causes fat, liver, and muscle cells to take in glucose. In this situation the effector protein for the signaling pathway is ---, a metabolic enzyme a transport protein a tyrosine kinase receptor a transcription regulator a leukotreine an actin-binding protein QUESTION 12 Signaling molecules are released all over the body. Target cells must express the correct gene encoding the protein in order for a ligand to find them. QUESTION 13 Match each item to the correct mode of signaling. Cancer cells near a blood vessel А. paracrine release a growth factor called VEGF, which binds to receptors on B. synaptic blood vessel cells. The blood С. contact-dependent (juxacrine) vessel cells begin to undergo mitosis (divide). D. no class of signaling Transmembrane proteins on a skin E. endocrine cell bind to transmembrane proteins on a neighboring fibroblast cell. The fibroblast cell rearranges its cytoskeleton and changes its shape. A neuron releases GABA, which binds to receptors on a neighboring neuron, causing them to open an ion channel to change membrane potential. Cells in the adrenal gland release cortisol, which binds to receptors on immune cells in the bone marrow. The immune cells begin to express anti-inflammatory proteins.

QUESTION 14 Neurotransmitters most often bind to --- receptors. QUESTION 15 What do all ligands/signaling molecules have in common? Check all that apply They are all molecules They can all enter the cell They can all bind to a receptor they start off the signal transduction pathway They are all proteins QUESTION 16 What do all receptors have in common? Check all that apply. they are all linked to G-proteins they are all transmembrane proteins when a ligand binds to them, they change shape they are all proteins all cells possess the same set of receptors QUESTION 17 What do ion channel receptors & G-protein coupled receptors have in common? Select all correct answers they trigger signaling pathways that include kinase cascades they stick out from the surface of cells they produce second messengers they change shape when a ligand binds to them they are 7pass transmembrane proteins
