To draw: A pathway of signal transduction including a ligand, receptor and a transcription factor that activates a gene that inhibits the receptor. Concept Introduction: Cell signaling involves a ligand, an extracellular molecule that acts as a signal to activate a membrane receptor protein which in turn, inhibits or activates the molecule. Inhibition refers to stop any reaction.

BIOLOGY: HOW LIFE WORKS (LOOSE-LEAF), Chapter 19.5, Problem 13SAQ

Fig 1: Pathway of signal transduction.

Explanation:

Signal transduction stands for a group of reactions that occur when a molecule such as hormone attaches to the receptor of cells. Signal transduction has three stages:

1. Reception: a protein molecule (ligand) primary messenger will detect chemical signals. Binding of ligand to receptor occur in this step.

2. Transduction: this will occur with the help of secondary messenger which will help in the stimulation of cells or some changes will take place in the cell.

3. Cellular responses: these can either be positive or negative. If the responses are positive then, it will activate some reactions and if they are negative then, they will inhibit the reactions.

Changes in gene expression occur because of the activation or inhibition.

Conclusion

In this cell signaling is done by using ligand. A ligand is an extracellular molecule that acts as a signal to activate a membrane receptor protein which in turn, inhibits or activates the molecules present in the membrane.

Discussion entries must be at least 250 words to fulfill the assignment requirements. You must complete your entry before you will be able to see the responses of other students. Responses to other students are encouraged but not required. Grading for discussion entries will be based on application of course concepts, proper grammar, and correct punctuation. Read one the attached article and explore the Human Development Index (https://hdr.undp.org/data-center/human-development-index#/indicies/HDI). In your opinion, is the Human Development Index a good measure of the well- being of the people of a nation? Are the items measured in the HDI valid and relevant in the modern global economy? How are they related to the political economy of a nation? The attached articles propose some alternative measures of well-being. In your opinion, are there other measures of well-being that might be better alternatives to the items in the current HDI?

A patient visits her doctor with symptoms typical of a bladder infection. She is immediately prescribed an 800 mgdose of antibiotic (bioavailability = 1/2, t½ = 12 h). The corresponding plasma concentration of drug is found to be 96 micrograms/ml. What is the volume of distribution of this drug? Please round to the nearest liter.

A 10 mg/Kg dose of a drug is given by intravenous injection to a 20 Kg dog. What would the volume of distribution be if the drug had been given orally and only 50% of the drug was absorbed (the concentration of drug at time = 0 is 0.1 mg/L)? Be sure to show your work.
