process by which cells communicate with each other

Question 2

basic components of cell signaling

Answer 2

1. ligand
2. receptor

Question 3

ligand

Answer 3

a signaling molecule; produced by a cell

Question 4

receptor

Answer 4

a protein located in or on a cell that binds the ligand

Question 5

signal transduction

Answer 5

chemical or physical signal is transmitted through a cell as a series of molecular events which ends in a cellular response

Question 6

stages of signal transduction

Answer 6

1. reception
2. transduction
3. response

Question 7

purpose of signal transduction

Answer 7

enable cells to respond to changes in the environment and coordinate activities in various cells in the body

Question 8

direct contact

Answer 8

direct physical contact between neighboring cells. can be done by a receptor and ligand binding from different cells

Question 9

cell communication can occur via

Answer 9

gap junctioning

Question 10

paracrine signaling

Answer 10

a type of cell signaling in which a cell produces a signal
to induce changes in nearby cells, altering the behavior of those cells

Question 11

synaptic signaling

Answer 11

type of cell communication
wherein a neuron communicates with its target
cell; type of paracrine signaling

Question 12

endocrine signaling

Answer 12

type of cell signaling in which hormones
are released into the bloodstream and act on distant target cells

Question 13

hormone

Answer 13

class of signaling molecules in
multicellular organisms that are sent to distant organs by
complex biological processes to regulate physiology and
behavior.
