Which one of these is not an example of intracellular communication?

A nerve cell stimulates a muscle cell to contract.

A signal is translated to cause muscle contraction.

A muscle cell action is coordinated.

A muscle cell maintains homeostasis.

When non-nerve cells become involved in response to signals, which type of receptor goes into action?

enzyme-linked receptor

ion channel-linked receptor

intracellular receptor

endomembrane receptor

Question 1 ) muscle cell maintains homeostasis is not an example of the intracellular communication.

Question 2 ) intracellular receptor goes into action When non-nerve cells become involved in response to signals.

1. The right answer is A nerve cell stimulates a muscle cell to contract (it is intercellular communication).

Cellular communication is the set of mechanisms that allow a cell, tissue, and organism to receive, interpret and respond to signals from other cells or its environment.

All cell types have these mechanisms but some have developed them more:

the nervous system,

organs of the senses,

endocrine system,

immune system.

This allows the body to maintain its homeostasis, its balance, allowing the interaction between these systems.

2. The right answer is the enzyme-linked receptor.

Receptor-enzymes associate on the same protein of the plasma membrane the functions receptor (mediator binding) and effector (enzymatic activity at the origin of intracellular message transduction): these are catalytic receptors. Thus, the receptor itself has enzymatic activity and the fixing of the messenger modulates this activity which may be of several types:

tyrosine kinase

tyrosine phosphatase

*receptors with guanylate cyclase activity
