Question
Chapter 45.3, Problem 3CC
Summary Introduction
To check knowledge of concepts: What are the similar properties and effects of epinephrine and auxin (plant hormone).
Concept introduction:
Hormones are signaling molecules produced by animals or plants. Hormones bind only to specific cells based on the corresponding receptors and trigger cellular response. In animals, the secreted hormones reach target cells through the bloodstream, whereas in plants, hormones act locally. Epinephrine and auxin are hormones produced from animals and plants, respectively. They are signaling molecules and they stimulate particular cellular responses in their corresponding organisms.

- Signaling molecules interact with cells through specific macromolecular receptors. For each of the four receptors identified below, list all characteris- tics, by number, which accurately describe that receptor. (a) An adrenergic receptor (b) A steroid receptor (c) The LDL receptor. (d) The insulin receptor, (1) Located at the cell surface (2) Associated with the protein clathrin (3) Ligand binding stimulates the activity of phospholipase C (4) A transmembrane protein (5) A DNA-binding protein (6) Located in the cell interior (7) Receptor-ligand complex moves to the lysosome (8) Receptor-ligand complex becomes concentrated in the nucleus (9) Receptor activation can inhibit the synthesis of glycogen (10) The hormone-receptor complex activates specific gene transcription (11) Internalization decreases the synthesis of cholesterol estersarrow_forwardFill in the gap Although signal transduction pathways are modeled mostly by ----------, there are some underlying difficulties in the modeling.

Explain the signal transduction pathway that occurs. 1. Is there a short term description for signal transduction, instead wrting multiple words to descripte the type of signal transduction?

Based on my understanding, active singal transduction is for the fast react transdcution, while inactive signal transduction meanly refers the hormonal affacts on the system. 2.
