Signal amplification is an essential step in signal transduction. Which of the following steps of signal transduction amplify the signal (select all that apply)?
Group of answer choices
a) ligand binding to receptor
b) release of GTP bound form of G protein from receptor
c) binding of GTP bound form of G protein to target enzyme
d) generation of second messenger by activated target enzyme
e) activation of gene expression
Homework Answers
1. Option a. Ligand is bound to the receptor
2.Option c. the receptor is activated when GDP is replaced by GTP. In GDP bound form the receptor is inactive. In GTP bound state the receptor is active.
3. Option d. Secondary messenger is generated by the active target enzyme.
4. Option e. Gene expression is upregulated by the activation of the secondary messenger.

Place the events in the correct sequence to explain signal transduction Molecular messenger transmits signal to effector proteins. Plant cell exposed to increased gibberellins. Effector proteins influence gene expression. Receptor molecule senses stimuli. The proteins produced influence cell division and elongation. Receptor molecule is converted to activated form. Receptor molecule senses stimuli.

2. You discover a signal transduction pathway that regulates actin polymerization. SigC is the ligand, which binds to and activates a receptor tyrosine kinase (RTK). Activation of the RTK leads to the activation of the Ras protein, which then activates the protein kinase PK1 that phosphorylates the RingA protein on S34. When SigC plasma membrane phosphorylated, RingA binds EXTRACELLULAR to the gene regulatory SPACE inactive Ras protein activated Ras protein protein, AP1....
