- 1What is the difference between endocrine signalling & NT signalling?Endocrine = Long range signals, hormonal, high-affinity receptors, longer diffusion distance, slower response rate
Synaptic = Short range signals, NTs, low affinity receptors, shorter diffusion distance, faster response rate - 2What is a chemical messenger?Biomolecule
- 3What is a receptor protein?h
- 4What determines speed of a message?h
- 5What determines speed of response to a message?h
- 6What is the relationship between the location of a hormone receptor & nature of message?h
- 7Why are gap junctions important in cell signalling?h
- 8Differentiate between endocrine, paracrine & autocrine signallingh
- 9Can one signalling molecule act differently on identical cells? Why?h
- 10Can one signalling molecule act differently on different cell types? Why?h
- 11What advantages come from having multiple locations for receptors?h
- 12What are the advantages/disadvantages of gap junctions over classical receptors?h
- 13Which signalling mechanism would you regard as more complex - Hormone or RTK pathways?h
- 14What is the significance between the different conc.s of hormones vs NTs in body?h
- 15Why do hormones travel relatively slow in comparison to NTs?h
- 16Name the most common mechanisms by which signals are terminatedh
- 17What are the most common protein hormones derived from?h
