Only oncopic receptors are membrane protein clonotropic receptors are directly linked and metabotropic receptors are indirect linked to lon channels d. Neurotransmitters are only involved with incroc receptors. e longropic receptors act owly, while metabotropic act quiddy w ould explan th 32. In an experiment, the membrane potential of a neuron is hyperpolated -120 mW. When an inhibitory neurotransmitter is...
With the aid of diagrams, compare and contrast the muscarinic (Gq-coupled) and nicotinic receptors with respect to location, structure, signalling and timescale of response.
Compare and contrast the structures of T cell receptors and MHC class II molecules. Relate the differences in structure to the function of the molecules in an immune response.

The following questions will require you to compare and contrast cell surface receptors and steroid hormone receptors. (a) Which type of receptor is more likely to have a hydrophobic ligand? (b) which type of receptor results in changes in gene transcription? Explain. (c) do peptide ligands usually travel to the nucleus with their receptors? (d) what is the benefit of a multistep signalling pathway over a single step signalling pathway?
Compare and contrast top-down vs. bottom-up approaches to starting lean. Answer with one paragraph.
6. Compare and contrast yeasts and molds: each
4. (6 Points) Compare and contrast the metabolism of “normal” versus tumor cells. What are tumor cells doing with the items they take in as “food?”
2. Compare and contrast the general sites and mechanisms of action of reserpine, clonidine, and methyldopa with those of drugs that block adrenergic receptors (for example, propranolol and phentolamine). 3. Explain the factors that lead to and the characteristics of the “rebound” phenomenon associated with sudden discontinuation of clonidine. 4. How responses to the main classes of adrenergic agonists would be affected.
