the feedback loop is part of the linear model of communication
Models of communication This is a one-way model to communicate with others. It consists of the sender encoding a message and channeling it to the receiver in the presence of noise. In this model there is no feedback or response which may allow for a continuous exchange of information (F.N.S. Palma, 1993).
Allosteric regulation Allosteric regulations are a natural example of control loops, such as feedback from downstream products or feedforward from upstream substrates. Long-range allostery is especially important in cell signaling.[1] Allosteric regulation is also particularly important in the cell's ability to adjust enzyme activity.
