Which of the following statements regarding second messengers (or signal transduction) is FALSE? They are needed to mediate the action of nonpolar regulatory molecules They are released from the plasma membrane into the cytoplasm of cells. They are produced in response to the binding of regulatory molecules to receptors m the plasma Membrane. They produce the intracellular actions of polar regulatory molecules. PLEASE CIRCLE TRUE OR FALSE (1 point each): True/False Steroid molecules are structurally different than triglycerides yet they are still classified as lipids because they are polar and soluble in water. True/False In paracrine scaling, hormones are secreted and enter the Wood and earned to all cells in the body. True/False Examples of second messengers include cyclic AMP. Ca^2+ ion, phosphoinostitol and cyclic GMP. True/False The two primary processes of intercellular bulk transport are diffusion and osmosis. True/False Most of the enzymes that perform primary active transport are transmembrane ATPases. True/False In coupled transport (or secondary active transport), the energy used to transport molecules across a plasma membrane relies on an electrochemical potential difference created by pumping ions in/out of a cell. SHORT ANSWER QUESTIONS: What are the functional (physiological) differences between white adipose and brown adipose?
35. The statement which is FALSE out of four statements is:
They are needed to mediate the action of nonpolar regulatory molecules.
Rest all the statements are true for a secondary messanger.
36. FALSE
Steroids are not water soluble and structure is also slight different tan triglycerides. But they are classified as lipids because they are also composed of fatty acyl estrs.
37. FALSE
In paracrine signalling, signalling mo,ecules are secreted to act on the nearby cells, by inducing some changes in the nearby cells. The signalling process in which the signalling molecule travels through blood, to act on the target cells, is Endocrine signalling.
38. TRUE
39. TRUE
40. TRUE
41. TRUE
42.
In the brown adipose tissue, the metabolism of glucose has been reported to be high. White adipose tissue has high expression of cytosolic malate dehydrogenase enzyme
