How will the individual's nutrition be impacted by this deficiency?Question:: Acyl CoA synthetase hydrolyzes ATP to AMP + PPI (pyrophosphate) as part of the activation of fatty acids to fatty acyl-CoA. Explain the role played by the enzyme inorganic pyrophosphatase in this reaction (in the activation of fatty acids to fatty acyl CoA) in the space provided below.
- Question 1: The overall process enabled by the glyoxylate cycle is: (2acetyl-CoA) + (NAD+) + (2H2O) → (succinate) + (2CoA) + (NADH) + (2H+) Dissect this process further by writing down all of the reactions that are actually involved in making one succinate from two acetyl-CoA units.

Given that the enzyme pyruvate carboxylase converts Pyruvate into Oxaloacetate and this is an anapleurotic reaction. In the liver, what is most of the OAA converted into under these conditions? Please explain. 1. When blood glucose levels are low and the energy charge in the cell is high. 2. When mitochondrial acetyl-CoA levels are high and the energy charge is low.Question 1: Part a: Assume that the standard free energy of ATP hydrolysis is -31 kJ/mol. Assume the following values for the standard free energy changes of the four reactions: HK -16.7 kJ/mol; PFK -14.2 kJ/mol; PGK -18.9 kJ/mol; PK -31.7 kJ/mol. (from bio.libretexts.org).

In gluconeogenesis, this step is simply reversed; i.e. it is not one of the three steps in gluconeogenesis that is driven by using different chemistry than that of glycolysis. How can this be? (Be specific: what specific factors could enable reversal of this step?)
