Epinephrine is a signaling molecule for
WebCell signaling depends on the ability to detect a signal molecule. Not all cells have receptors for epinephrine. Only cells with such receptors are capable of responding. Signal transduction may result in changes in gene expression and cell function, which may alter phenotype in an embryo. WebMar 6, 2024 · Epinephrine (Figure 7.142), also known as adrenaline, is a catecholamine that plays an important role in the body's 'fight or flight' response. In response to stressful stimuli, epinephrine is secreted into the blood, to be carried to target organs whose cells will respond to this signal.
