cell signalling

Question 1

describe direct cell signalling

Answer 1

transfer between pores/connections on adjacent cells

Question 2

describe paracrine cell signalling

Answer 2

a molecule carries a cell signal from one cell to another

Question 3

describe endocrine cell signalling

Answer 3

hormone released into the blood and carried to a cell of another organ

Question 4

describe synaptic cell signalling

Answer 4

neurotransmitter released into a synapse in order to transfer signal to the next cell

Question 5

describe autocrine cell signalling

Answer 5

ligand is released from its own cell, attaches to the membrane, causing change

Question 6

what happens at ligand gated receptors

Answer 6

ligand binds to ion gated channel, opening the channel

Question 7

what happens at G protein coupled receptors

Answer 7

the receptor is transmembrane- hormone binds to the receptor on outside of the cell, causing the inside to bind to another protein triggering a secondary messenger

Question 8

what happens at steroid receptors

Answer 8

hormone binds to receptor on cytoplasm and signal is carried to the nucleus

Question 9

what happens at enzyme linked receptor

Answer 9

ligand binds to receptor sit, causing a kinase cascade
