Depending on the exact response, the substance is generally called a pathogen, yet more specifically depending on the nature of the response and origin of the substance, could be an antigen, allergen, carcinogen, etc.

What is the difference between stimulas and response?

A stimulus is an external event or cue that triggers a reaction in an organism, while a response is the specific reaction or behavior that follows the presentation of a stimulus. In simpler terms, a stimulus is something that causes a response.


What binds to a signal molecule enabling the cell to respond to the signal molecule?

A receptor protein on the cell membrane binds to the signal molecule, initiating a series of intracellular events that lead to a cellular response. The binding of the signal molecule to the receptor triggers a signaling cascade that ultimately activates specific cellular pathways.


When cell signaling causes a response in the nucleus what happens?

When cell signaling causes a response in the nucleus, transcription factors are activated. These transcription factors then enter the nucleus and bind to specific DNA sequences, leading to the regulation of gene expression. This can result in the production of specific proteins that mediate the cellular response to the initial signaling event.


An allosteric receptor embedded in a cell membrane will change shape only?

An allosteric receptor embedded in a cell membrane will change shape in response to the binding of a specific molecule or ligand, which causes a conformational change in the receptor. This change in shape can alter the receptor's ability to interact with other molecules or signaling proteins within the cell, ultimately triggering a cellular response.


Difference between stimulus and response?

A stimulus is a change in an organism's surroundings or body which causes it to respond. Hence, a response is an organism's reaction to a specific stimulus.


What is a factor that causes a response?

A stimulus is a factor that causes a response in an organism.


What does an antigen do?

An antigen is a substance that triggers an immune response in the body, by stimulating the production of antibodies. This response helps the body to recognize and destroy harmful pathogens such as bacteria, viruses, or foreign substances.
