Homework Answers
Ans- Correct order of signal transduction pathway are: 4,5,1,6,2,3.
Ligand binds to a receptor.
A receptor undergoes a confirmation so change.
An inactive signal transduction molecule is activated.
An active signal transduction molecule binds to a transcription factor.
A transcription factor enters the nucleus.
A gene is expressed.
Hence, signal transduction pathway is started by binding of a ligand to it's receptor. Ligand is the signal molecule in the signaling pathway. And, after completion of this pathway gene is expressed that results in cellular response.

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....

1. You are interested in how
cyclic-AMP-dependent protein kinase A (PKA) functions to affect
learning and memory, and you decide to study its function in the
brain. It is known that, in the cells you are studying, PKA works
via a signal transduction pathway like the one depicted in Figure
16-15. Furthermore, it is also known that activated PKA
phosphorylates the transcriptional regulator called Nerd that then
activates transcription of the gene Brainy. Which, if any
of the situations described...

1. A person has a mutation in their leptin gene, such that the leptin they make cannot bind to the leptin receptor. What do you predict about their weight/BMI? WHY? 2. A person has a mutation in their leptin receptor, such that it can bind to leptin, but then the receptor fails to activate. Will leptin be a viable treatment for this person? WHY? 3. Insulin binds to an insulin receptor on a cell. The receptor dimerizes and becomes phosphorylated...
