A Deficiency on 3-Phosphogtycerate Dehydrogenase Can Affect Amino Acid Metabolism Although serine is a nonessential amino acid, serine deficiency syndrome has been observed in humans. One such form of the syndrome is traceable to a deficiency in 3-phosphoglycerate dehydrogenase (see Figure 25.31). Individuals with this syndrome not only arc serine-deficient but also arc impaired in their ability to synthesize another common ammo acid, as well as a class of lipids. Describe why.
Name one reaction of glycolysis, one anaplerotic reaction, and one reaction of TCA cycle that acetyl-COA allostericqally regulates ( and declare whether it is an activator or inhibitor.)
Fatty acids are activated for breakdown through the action of acyl-CoA synthestase. Which of the following statements regarding acyl-CoA synthetase is not true? ● It catalyzes the addition of CoA to the fatty acid One of the products of the reaction is ADP. O The free energy change for the reaction catalyzed by this reaction is close to 0 kJ/mol, but the subsequent hydrolysis of pyrophosphate drives the reaction forward. O The reaction results in the formation of a thioester bond.

Glucagon secretion inhibits intracellular acetyl-CoA carboxylase activity through a number of different methods. Make a list of everything that comes to mind.
Fatty acid biosynthesis begins with the condensation of a two-carbon acetyl residue from acetyl-COA and oxaloacetate, while oxidation leads to the release of two carbon units, acetyl-CoA and fatty acyl-CoA. However, these two processes are not simple reversal. Compare and contrast these two pathways.

Some bacteria use the citric acid cycle intermediate, α-ketoglutarate, plusacetyl-CoA, as the starting point for lysine biosynthesis. The first partof this biosynthetic pathway uses the same chemical strategy found inthe citric acid cycle. Propose a four-step pathway for the conversion ofα-ketoglutarate to 2-oxoadipate. Draw the three missing intermediates, andindicate the chemistry involved in each reaction. Include any cofactors thatyou think might be required for specific steps.
