Description : Without saturation of transport proteins and under same concentration gradient how can the speed of simple diffusion be compared to the speed of facilitated diffusion ?
Last Answer : The action of facilitator proteins in facilitated diffusion makes this type of diffusion faster than simple diffusion under equal concentration gradients of the moved substance.

Which of the following statement(s) is/are true ... physiologic role of acute phase proteins are to reduce the systemic effects of tissue damage
Last Answer : Answer: c, d IL-6 is now recognized at the cytokine primarily responsible for the alteration in hepatic synthesis recognized as the acute phase response. Glucocorticoid hormones augment ... that generally inhibit the tissue destruction that is associated with the local initiation of inflammation

Description : Give examples for allosteric inhibition.
Last Answer : ALA synthase, aspartyl trans-carbamoylase, HMG CoA reductase
Description : Give examples for suicide inhibition.
Last Answer : Ornithine decarboxylase (ODC) is inhibited by difluro methyl ornithine (DFMO). Another example is Allopurinol which is oxidised by xanthine oxidase to alloxanthine that is a strong inhibitor of xanthine oxidase.

Last Answer : Di-isopropyl fluoro phosphate inhibits trypsin, fluoride inhibits and enolase.
Description : Give examples of clinical application of competitive inhibition.
Last Answer : Sulfonamide inhibits PABA incorporation in bacteria, and so acts as an antibacterial agent. Methotrexate inhibits folate reductase system, dicoumarol inhibits vitamin K.
Description : Give examples of competitive inhibition.
Last Answer : Malonate inhibits succinate dehydrogenase.
Description : Give some examples of co-enzymes involved in reactions other than hydrogen transfer.
Last Answer : Thiamine pyrophosphate, pyridoxal phosphate, biotin, co-enzyme A, ATP.

Description : Give some examples of anionic precipitating agents.
Last Answer : Tungstic acid, phosphotungstic acid, trichloro acetic acid, picric acid, sulphosalicylic acid and tannic acid are protein precipitating agents.
Description : Give examples of decarboxylation reactions.
Last Answer : Histidine to histamine; tyrosine to tyramine; tryp- tophan to tryptamine.
Description : Give examples of derived amino acids.
Last Answer : Hydroxy proline, hydroxy lysine, ornithine, cit- rulline, homocysteine.

Last Answer : Sodium dependent glucose transporter (SgluT) (Fig.8.31). Phlorhizin, an inhibitor of sodium-de- pendent cotransport of glucose, especially in the proximal convoluted tubules of kidney, produces renal damage and results in renal diabetes. Amino acid transport is another example for symport.
