Paracrine Your Answer: Paracrine signaling Identify the type of signaling shown in the figure: Question 2 2 /^2 pts Correct! False True True or False. Intracellular signaling is a type of cellular communication that occurs among two or more cells. Question 3 2 /^2 pts
Endocrine function for regulatory processes include each of the following except: Blood pressure Blood volume Correct! (^) Vision Energy metabolism Growth Sexual reproduction Correct! Synaptic Autocrine Paracrine Endocrine Multiple Choice: Insignaling, the ligand is not transported through the blood, but is transported by diffusio Question 5 2 /^2 pts
Question 6 2 /^2 pts
Fill in the blank. signaling is characterized by ligands, manufactured and stored within neu blood to reach the target cell. Your Answer: paracrine Question 8 0 /^2 pts
Neuroendocrine Pheromones Your Answer: Pheromones Fill in the blank. are ligands that are released into the external environment by animals wh claim territory. Question 9 2 /^2 pts
hydrophilic hydrophobic external/cell surface (GPCR is also acceptable answer) cell surface AND intracellular (need both answers) intracellular Your Answer: external G-protein cell surface receptor or if lipid soluble will bind to intracellular receptor do not bind to cell surface but bind intracellularly to directly change gene expression in th Listed below are the types of hormone ligands. Name the type of receptor that each will b polypeptide amine steroid Question 11 3 /^3 pts
Multiple Choice: Question 12 2 /^2 pts
Steroid Your Answer: steroid Fill in the blank. hormones are a class that is characterized as non-polar, lipid soluble ligan receptors of target cells. Question 14 2 /^2 pts
Correct! Correct! Correct! activation of neighboring receptors activation of neighboring cells alteration of enzyme activity second messenger activation change in cell membrane permeability The binding of a ligand to receptor can cause the following (select all that apply): Question 15 2 /^2 pts
Correct Answer (^) adenylyl cyclase activates cAMP ou Answered (^5) Correct Answer (^) cAMP activates protein kinase A Correct! 6 protein kinase A inhibits adenylyl cyclase is activa cAMP activates protein Question (^17 5) / 5 pts Below is a signal transduction pathway that pertains to the production of vitellogenin in birds and frogs. Fill in the missing terms: Estradiol, a 1 hormone, is transported to the target cell. It migrates through the 2 and binds to the estradiol receptor located in the 3. Once bound, the 4 translocates into the nucleus. The complex will attach to a specific gene along the DNA. Binding causes the 5 of mRNA for a protein, vitellogenin. Your Answer:
- hydrophobic
- plasma membrane
- cytosol
- receptor horomone complex
Multiple Choice: Autocrine and paracrine signaling are associated with each of the following ligands except: Question 19 2 /^2 pts
cytokines prostaglandins Correct! estrogen nitrous oxide inhibitory Your Answer: inhibitory neurotransmitters Fill in the blank. Neurotransmitters that increase the electrical threshold of the post-synaptic cell are classified as. Question 20 2 /^2 pts naanssweereded . Question 21 0 /^4 pts The following paragraph pertains to neurotransmitter signaling. One key event has been omitted. Explain the missing event. Neurotransmitters are synthesized and stored within synaptic vesicles at the axon terminal. An electrical impulse is propagated down the axon, and the permeability of the axon terminal is changed. The neurotransmitter ligand binds to extracellular ion-gated ligand channels on the postsynaptic cell.
