Answer 1

901). False ... It is done by HDL.  

LDL on the other hand transports Plasma low density lipoprotein (LDL) transports cholesterol from liver to peripheral tissues including the adrenal glands and gonads.... This is also known as bad cholestrol ... As it contirbutes in ibesity and atherosclerosis...

911). True... As

The final product of the fatty acid synthase reactiono is a free rather than an activated (esterified) fatty acid due to the presence of a thioesterase activity which in eukaryotic systems is an integral part of the fatty acid synthase enzyme . The esterase is relatively specific for acyl chains containing 16

)

carbons, resulting in the specific release of palmitic acid in most biological systems....

921). True ... Eicosanoids are formed from arachidonic acid by the enzyme Phospolipase A2 which is inhibited by steroids... Arachidonic acid is an unsaturated fatty acid found ubiquitously in plasma membranes, where it is bound to phospholipid. Its metabolism produces prostaglandins, prostacyclins, thromboxanes, and leukotrienes (eicosanoids). Eicosanoids are chemical mediators of inflammation...

931). True... The precursor molecule for both de novo synthesis and salvage of purines and pyrimidines is the activated form of ribose 5-phosphate, 5-phosphoribosyl-1-pyrophosphate (PRPP). ... The reaction consumes two high-energy bonds by transferring a pyrophosphate group to the ribose sugar....

961 ). True.... Uric crystals deposit in gout which lead to inflammation of small joints ....
