Chapter 9.3, Problem 2LO
Summary Introduction
To determine: The signal transduction pathway through intracellular receptors.
Introduction: The intracellular receptors are the receptors that are present within the cell and help in the process of signal transduction. The receptors are present in the cytoplasm and on the nucleus. These receptors are used by the steroid hormones and the thyroid hormones.
