Direct intercellular signaling = A signaling molecule passes between the cytosol of adjacent cells through a cell junction Show Contact-dependent signaling = A membrane-bound signaling molecule binds to a receptor on the surface of another cell. Autocrine signaling = A signaling molecule binds to a receptor on the same cell that secreted the signal. Paracrine signaling = A signaling molecule affects target cells nearby but not the cell that secreted the signal. Endocrine signaling = A signaling molecule acts on target cells distant from the cell that secreted the signal. What is the first step in this signal transduction pathway?1. Reception: A cell detects a signaling molecule from the outside of the cell. A signal is detected when the chemical signal (also known as a ligand) binds to a receptor protein on the surface of the cell or inside the cell.
What is the role of cAMP in a signal transduction pathway quizlet?What is the role of cAMP in a signal transduction pathway? Correct This answer choice is correct because cAMP is a second messenger; it carries a signal from the G protein-coupled receptors to the beginning of the phosphorylation cascade.
What is the correct order of a signal transduction pathway quizlet?What are the four steps of signal transduction? (1) signal molecule binds to receptor that (2) activates a protein that (3) creates second messengers that (4) creates a response. What happens during amplification?
What occurs during the process of signal transduction?Signal transduction is the process in which binding of an extracellular messenger to the cell surface receptor is translated into changes in biochemistry, cell biology, and gene transcription that make it possible for the cell to respond to the information that was received.
