- My question is Explain why you feel numbness when using a topically applied pain cream that contains lidocaine.Lewis structures of mescaline, a hallucinogenic compoundin peyote cactus, and dopamine, a neurotransmitter in the mam-malian brain, appear below. Suggest a reason for mescaline’sability to disrupt nerve impulsesYou can choose one or more than one option The dissociation constant (Kd) of a receptor is: BIOCHEMISTRY basic the concentration of a ligand that produces 100% occupancy of the receptor the concentration of a ligand that produces 50% of the maximal effect. the measurement of specificity between ligand and its receptor. the measurement of speed by which a ligand will dissociate from its receptor. the measurement of affinity between a ligand and its receptor and the inverse of the association constant. During an experiment with Drosophila, it was discovered that all females had red eyes. unlike males. A conclusion based on this observation would be: MOLECULAR BIOLOGY basic The gene for eye color is located on the X chromosome. The females are homozygotes The gene for eye color is dominant. The eye color results from multigenic linkage. The eye color phenotype is sex-linked A secondary lysosome: CELL BIOLOGY advanced a lysosome that provides a backup to the primary…
- added ligand concentration of 10 µM is 5 × 10³ s¹. What is the value of the reverse rate constant k_1 = 1 ×10-4 Incorrect Macmillan Learning You have not correctly calculated the value of the reverse rate constant. To begin, calculate the value of k₁ by dividing the rate of receptor-ligand complex formation (the rate of the forward reaction) by the ligand concentration. k₁ = rate forward [L] Then, calculate the value of the reverse rate constant, k_₁, by multiplying the dissociation constant, Kd, and the forward rate constant, k₁. k_1 = Kak₁The Table below shows the names of proteins whose functions are regulated through the binding of their ligands. Complete this Table by filling in the correct ligands for each of the proteins, the corresponding K, value, the affinity of this protein for its ligand and the source where the protein is found. Example Protein Avidin 1 Insulin receptor 2 Anti-HIV immunoglobulin 3 Nickel binding protein 4 Myoglobin 5 Myosin 6 Acetyl-CoA carboxylase 7 Cannabinoid receptor 1 (CB1) 8 Guanylyl cyclase Ligand Biotin Kd (M) 1 x 10-15 Affinity high Source/Organism Egg white2 of 16 Compound Binds to Elicits biological receptor response A Yes Yes B Yes No C No No Refer to the table above. Compound X is the natural ligand that binds to a receptor and stimulates a signal transduction pathway associated with the receptor. Based on the information given in the table, what are the roles of compounds A, B, and C? O A is an antagonist, B is an agonist, and C is a ligand. A is an agonist, B is an antagonist, and C has no role. A is a ligand, B has no role, and C is an antagonist. A is an agonist, B is an antagonist, and C is an agonist. A has no role, B is an agonist, and C is an antagonist.
