Fill in the blanks: (1) The provides a point-to-point rapid coordination among organs. The ..2.. coordination is fast but short lived (3) As the ...3 do not innervate all cells of the body and the cellular functions need to be continuously regulated, a special kind of coordination and integration has to be provided. This function is carried out by ..4...A. l-endocrine system, 2-neural, 3-nerve fibres, 4-hormonesB. l-neural system, Z-neural, 3-nerve fibres, 4-hormonesC. l-neural system, 2-endocrine, 3-hormones, 4-neuronsD. l-endocrine system, 2-neural, 3-hormones, 4-neurons |
|
Answer» Correct Answer - B The neural system provides a point-to-point rapid coordination among organs. (ii) The neural coordination is fast but short-lived. (iii) As the nerve fibres do not innervate all cells of the body and the cellular functions need to be continuously regulated, a special kind of coordination and integration has to be provided. This function is carried out by hormones. |

Answer» Correct Answer - C Insulin is a protein hormone which is water soluble. Water so,luble hormone require extracellular receptors that generatre second messengers for carrying out their activity. Insulin binds to its specific receptor molecule located on the plasma membrane to form the hormone receptor complex, (HRC) which in turn generate second messengers that regulate cellular mechanism. Water soluble hormones (a.g., amono aci dderivatives, peptides and protein hormones) do not enter the target cell. |
