Answer #1

Phosphorylation.

Phosphorylation can cause the protein molecule to be activated, inactivated or give the protein molecule specific functions by compartmentalizing the specific protein molecules. Phosphorylation is simply the addition of phosphate. Here, the phosphate is added to the protein molecule to make it activated or inactivated or compartmentalized. In this, the protein is modified in a way which involves the phosphorylation of amino acid residue in the protein by a protein kinase.

Let’s assume that one molecule of epinephrine binding to the cell activates one G-protein, which activates one adenylate cyclase. From there, assume that every enzyme catalyzes 10 reactions (for example, each activated adenlylate cyclase produces 10 molecules of activated cAMP dependent protein kinase). Finally, assume that each activated glycogen phosphorylase “frees” 10 molecules of glucose to be released from the cell into the bloodstream. Consider that the epinephrine is only present when you see the jaguar, so prior to that...

Signal transduction pathways are central to the regulation of cellular processes. Which of the following statements is not true of signal transduction pathways? Group of answer choices Signal transduction pathways typically involve the activation of protein kinases and protein phosphatases. When a hormone binds to a G-protein-coupled receptor, a conformational change in the receptor activates the associated GTP-binding protein. Intracelluar second messenger molecules include cGMP, calcium ions and inositol trisphosphate. A receptor protein has an extracellular domain that is responsible...

The Central Dogma Explain how our genes control our traits with a specific example. Your explanation should contain the following words: transcription, translation, gene, mRNA, and protein. You should include the name of a specific gene and a specific protein, and try explain how the role of that particular protein relates to the trait (example: the pigment melanin is a protein that results in brown eyes, skin and hair). To demonstrate that you have understood how transcription and translation works,...

You are investigating the regulation of the eukaryotic fledermaus gene (fm). Analysis of many types of data have indicated that the gene products listed below are all involved in regulating the expression of fm. For each gene product, state the most likely mechanism by which it regulates expression of fm and whether it most likely inhibits the gene, activates the gene, or whether there is insufficient information to say. The gene sequence of this protein shows that it has a...
