Remaining V Ha Question 17 Triose phosphate isomerase catalyzes the conversion of Glyceraldehyde-3- phosphate to Dihydroxyacetone phosphate. Glyceraldehyde-3-P Dihydroxyacetone phosphate The Km of this enzyme for its substrate Glyceraldehyde-3-phosphate is 1.8 x 10 M. When [Glyceraldehyde-3-phosphate] = 30 uM the rate of the reaction (v) was 82.5 umol/mL/sec and the Vmax was 132 umol/mL/sec. Assuming 3 nanomoles/mL of enzyme was used ([Eotal = 3 nanomol/mL) the kcat for this enzyme is: Select an answer and submit.

Please answer fast The equilbrium constant (Keq) under standard conditions for the hydrolysis of ATP is 200,000 M. This would suggest the reaction is: 1. proceeding in reverse direction 2. proceeding in forward direction 3. in equilibrium However, this does not take into consideration the concentration of substrates/products within the cell. This is can be calculated by determining the reaction quotient, Q by: [ATP] x [Pi] / [ADP] [ATP] + [Pi] / [ADP] [ADP] x [ATP] / [Pi] [ADP] x [Pi] / [ATP] Biochemical reactions commonly involve the transfer of groups from ATP. What is one of the products of pyrophosphate cleavage from ATP? AMP Adenosine ADP Inorganic phosphate Q5-6. The hydrolysis of ATP is often coupled to other reactions. For example: Phosphoenolpyruvate (PEP) + H2O → Pyruvate + Pi (ΔG'° = -63.1 kJ/mol) ATP + H2O → ADP + Pi (ΔG'° = -30.5 kJ/mol) (The standard free-energy changes for the reactions are indicated in brackets) Q5. Given the information above, what is the…
