Fatty acid biosynthesis occurs through a series of reactions involving fatty acid synthase (FAS), a polypeptide multienzymecomplex. The result of this synthesis is a saturated fatty acid with up to 16 carbon atoms (palmitic acid). Longer fatty acids andunsaturated fatty acids result from modifications to fatty acids produced by FAS activity.What saturated fatty acid gives rise to myristoleic acid, CH3(CH2)3CH=CH(CH2),COOH?H₂H₂OHཔཱལིནཊྛདྡྷིསཏྟཔཱཎཱསིངྒཱརཨིནྡྷནཾ ཀིཾསུfatty acid + O2 + NADPH + H+H3CHHmyristoleic acid+ 2 H2O + NADP+Modufy the given molecule of myristoleic acid to show the fatty acid used to produce myristoleic acid.H₁C||НHOH

Can u help me to explain to me, please? I stuggled my homework and i need help to understand it
(b) Biotin is a coenzyme required for a key step in gluconeogenesis. (i) To which enzyme is biotin linked and what is the nature of the bond? (ii) What properties do the biotin and the linkage have that enable biotin to interact with two distinct active sites in this enzyme? (iii) What chemical steps take place at each of these active sites (no need to specify the complete reactions)?
Which of the following statements are descriptions of metal ion catalysis or examples of metal ion catalysis? Choose all correct answers a Zn²+ cofactor may properly orient the substrate in the active site through ionic interactions. a covalent bond forms between enzyme and substrate lowers the energy or stabilizes the transition state or intermediate catalyst retains its original form after reaction occurs catalysts may participate in oxidation-reduction reactions by changes in the oxidation state
Which of an alpha-D-2,3-di-O-methylglucopyranose or alpha-D-2,3, 6-tri-O-methylglucopyranose represents a glucose unit in glycogen which was originally carrying an (alpha 1-->6) glycosidic bond?
Draw the products that would be produced from phospholipase C cleavage of a glycerophospholipid with a phosphoserine head group, an alpha linoleic acid attached to C2 of glycerol and a linoleic acid attached to C, of glycerol. Draw these products at pH=1. Be sure to number the fatty acid carbons in your products.
Compare and contrast the biological roles of the following amino acids the following pairs ofamino acids. Once you have documented these role state which member of the pair is most important and why.
Fatty acid biosynthesis provides for energy storage over [ Select ] ["longer", "shorter"] time periods than that of glycogen. It is assembled by sequential addition of [ Select ] ["three carbon units", "2 carbon units, acetyl-CoA"] . Fatty acid synthesis occurs in [ Select ] ["the mitochondrial matrix", "the cytoplasm"] and generation of [ Select ] ["Malonyl-CoA", "acetyl-CoA"] is rate limiting. Fatty acid synthase, by multiple rounds of carbon molecule addition, achieves the generation of palmitate, with the consumption of [ Select ] ["ATP and NADPH", "phosphocreatine and NADH"].
Why does it make good metabolic sense for phosphoenolpyruvate carboxykinase, rather than pyruvate carboxylase, to be the primary target for the regulation of gluconeogenesis at the level of control of enzyme synthesis?
