"'ll AT&T; 1:22 PM 57% EXTRA CREDIT.docx Lys 15C Which change to an equilibrium mixture of compounds 1-4 will increase the ratio of compound 4 to compound 1? A) Adding compound 3 b) Increasing the temperature c) Adding more catalyst and pyridoxal phosphate d) Adding compound 2 15D What thermodynamic and chemical changes (if any) occur during aspartate transamination? A) Since ?G is less than 0, ATP is produced b) Since ?G-0 no ATP is required or produced c) since AG is greater than 0, ATP is required d) since AG is greater than 0 ATP is produced 15E When Asp reacts with pyridoxal phosphate, arn intermediate called pyridoxamine is formed and oxaloacetate is released. The reaction is reversible.Which biological molecule can react with pyridoxamine to regenerate pyridoxal phosphate? A) ATP b) oxaloacetate c) NADH d) FAD+ 16. The overall reaction for glycolysis is: Glucose+ 2NAD+ + 2Pi 2 pyruvate + 2NADH + 2H2ATP+2H2O. This may be broken down into two separate processes (reactions 1 and 2 Reaction I : Glucose + 2NAD+ 2 pyruvate + 2NADH + 2H+ AG for this process is -146 Kj/mol Reaction 2: ADP+Pi-ATP+H2O AG for this process is +30.5 Kj/mol What is the overall ?G for glycolysis? A) -207.0 KJ/mol b)176.5 KJ/mol c) -85.0 KJ/mol d) -54.5 KJ/mol Open With PrintExplanation / Answer
Answer 15C – option d – adding compound 2
Answer 15D – option c – since delta G is greater than 0, ATP is required
Answer 15E – option B – oxaloacetate ( it reacts with an ?- ketoacid to regenerate pyridoxal phosphate)
Answer 16 – option C - -85.5 kJ/mol
