What disrupts cell signaling?
Different cells can respond in different ways to the same signal. The way a cell responds to a particular signal depends on the signal transduction pathways present in the cell.For example, sensory cells in the skin respond to the pressure of touch, whereas similar cells in the ear react to the movement of sound waves. In addition, specialized cells in the human vascular system detect changes in blood pressure — information that the body uses to maintain a consistent cardiac load.Example: Apoptosis

For example, most animal cells have receptors that interact with the extracellular matrix, a supportive network of proteins and carbohydrates. If the cell moves away from the extracellular matrix, signaling through these receptors stops, and the cell undergoes apoptosis.

What else could interfere with proper functioning of the pathway : Factors that could interfere with proper functioning of the signal transduction pathway include environmental conditions causing proteins to be denatured, mutations, and presence of inhibitors or activator molecules.

What are examples of cell signaling responses

Cellular responses can be extremely rapid – for example, the opening of ion channels to effect a change in the membrane potential or the contraction of muscle fibres, which occur within milliseconds of signal reception, or may take minutes, such as whole cell movement, synthesis of new proteins or changes in metabolic …

What causes the cellular response : Many signaling pathways cause a cellular response that involves a change in gene expression. Gene expression is the process in which information from a gene is used by the cell to produce a functional product, typically a protein. It involves two major steps, transcription and translation.

Termination of a signal at the appropriate time can be just as important as the initiation of a signal. One method of stopping a specific signal is to degrade the ligand or remove it so that it can no longer access its receptor.

How might a cellular response be inhibited In G protein systems that inhibit adenylyl cyclase, a different signaling molecule activates a different receptor, which in turn activates an inhibitory G protein.

What can disrupt signal transduction pathways

A Signal Transduction Pathway may be disrupted because of internal or external factors. Internal factors include changes in the cells themselves, commonly called mutations. External factors include environmental parameters like temperature, PH, Chemicals, and many more.Cell communication can be disrupted in several different mechanisms. One way is by altering one or more proteins of the signaling cascade so that they cannot receive and amplify the signal. Chemical messengers can also be blocked from traveling or reaching the target cells.There are four basic categories of chemical signaling found in multicellular organisms: paracrine signaling, autocrine signaling, endocrine signaling, and signaling by direct contact.

The different types of cell signalling include:

  • Paracrine signalling.
  • Autocrine signalling.
  • Endocrine signalling.
  • Direct Contact.

How might a cellular response be inhibited : How might a cellular response be inhibited In G protein systems that inhibit adenylyl cyclase, a different signaling molecule activates a different receptor, which in turn activates an inhibitory G protein.

What changes can alter cellular response : Changes in signal transduction pathways alter cellular response by altering the protein and enzyme synthesis, thereby affecting processes like binding messenger molecules to the receptor.

How is cell signaling halted

The most obvious method for turning off a signal is the dissociation of the ligand from the receptor. Ligand dissociation can be induced (a cellular process),or can occur due to a decrease in the circulating ligand concentration.

For example, most animal cells have receptors that interact with the extracellular matrix, a supportive network of proteins and carbohydrates. If the cell moves away from the extracellular matrix, signaling through these receptors stops, and the cell undergoes apoptosis.The binding of cellular receptors to the extracellular matrix initiates a signaling cascade within the cell. However, if the cell moves away from the extracellular matrix, the signaling ceases, and the cell undergoes apoptosis. This system keeps cells from traveling through the body and proliferating out of control.

How are signaling pathways inhibited : In this process, small molecules called signal transduction inhibitors block the communication between different molecules of the pathway. These signals control many cellular processes, including growth, cell division, and death.
