Question
Chapter 38, Problem 17TYU
Summary Introduction
To determine: Whether expanding knowledge of the molecular basis of plant signaling molecules could improve agricultural productivity in the future.
Introduction: Plant hormones are chemical molecules produced by plants in extremely low concentration for regulating growth and development. Many of the signaling molecules in plants are also involved in defensive response against disease and insects.

Give an example for each type. What are the signaling molecules in the plant? Please describe each of them briefly.arrow_forwardDuring signal transduction (a) the cell converts an extracellular signal into an intracellular signal that leads to a change in some cell process (b) a signaling molecule directly activates or represses several genes (c) each enzymecatalyzes production of one molecule of product (d) enzymes in the signal cascade remain active until the last component of the pathway alters a cellular process (e) the signal is terminated by cyclic AMParrow_forward

They decrease the speed of signal transduction in the pathway.arrow_forwardPlease answer question 3arrow_forwardIf an animal cell suddenly loses the ability to produce GTP, what will most likely happen to its signaling system? It will not be able to activate G proteins on the cytoplasmic side of the plasma membrane. O It will be able to carry out reception and transduction but would not be able to respond to a signal. O It will use ATP instead of GTP to activate G proteins on the cytoplasmic side of the plasma membrane. O It will not be able to activate receptor tyrosine kinases.arrow_forward
