Describe endocrine, paracrine, and autocrine signaling. correct answers Endocrine: An endocrine cell releases a hormone into the blood stream to target a receptor on the target cell. Paracrine: A signaling cell releases a local mediator to target cells (neighboring cells). Autocrine: A cell releases a chemical signal to target itself. How does a hormone that is released generally throughout the body end up having different effects on (or no effects on) different cells? correct answers H...

BIO 1A03 Test 2 Questions and Answers Already Passed one gene-one enzyme hypothesis each gene contains the information needed to make an enzyme What did George Beadle and Edward Tatum research? Relationship between genes and proteins using the Neurospora Crassa One gene-one enzyme hypothosis (Neuroposa Example) Neurospora can grow well on minimal medium (simple sugar, vitamins, inorganic salts), and therefore it must have enzymes produced by a certain gene that that transform these materials i...

What is dimerization? Ans: The process of 2 receptors coming together at 2 half sites. Heterodimer - examples Ans: - pituitary - placenta gonadotropin - follicle stimulating hormone Homodimer - examples Ans: (RNP) - Ribosome 2 - Nucleosome - Proteasom

CPPS 325 FINAL EXAM QUESTIONS WITH CORRECT ANSWERS 2023/2024 Graded A+. What is the only example of conformational change activation? - Correct Answer-Insulin receptor kinase. All other RTKs are activated through forms of dimerization. What are the two forms of dimerization? - Correct Answer-i) Receptors exist as unactivated dimers until ligand binds (Twist theory) ii) exist as monomers that are brought together and activated by ligand binding. What is the most common method of dimerizatio...
