Signal transduction is a mechanism in which the cell responds to a signal from the environment by activating several proteins and enzymes that will give a response to the signal. Feedback mechanism might involve negative and positive feedbacks. In the negative feedback, the pathway is inhibited and the result of the transduction pathway is reduced or limited. In positive feedback, the transduction pathway is promoted and stimulated to produce more products.

Nettet18. des. 2016 · It should be noted that the feedback mechanisms work by reversing the stimulus, whichever direction that stimulus is going. In the blood sugar example, the pancreas releases insulin when blood sugar levels are increasing. This causes blood sugar levels to decrease, reversing the trend back to normal. csulb international businessNettet3. apr. 2024 · Previous studies have found that blood glucose levels affect insulin absorption because of the blood glucose–insulin feedback mechanism (Fernqvist-Forbes et al., 1988).
