During glycolysis an enzyme, TPI, converts dihydroxyacetone phosphate (DHAP) to glyceraldehyde 3-phosphate (GAP) according to the balanced equilibrium equation shown
below.
DHAP GAP
At equilibrium, GAP has a concentration of 0622 M and DHAP has a concentration of 0.018 M.
What is the equilibrium constant for this equilibrium?

question, enter the unrounded value. Carmen may add or remove zeros from your response, your
submission will still be graded correctly if this happens.

All cells are made of four types of acids, lipids, proteins, and carbohydrates.

Lab reagent, hypothesis test. a reference solution used as a lab reagent is purported to have a concentration of 5 mg/dl. six samples are taken from this solution and the following concentrations are recorded: (5.32, 4.88, 5.10, 4.73, 5.15, 4.75) mg/dl. these six measurements are assumed to be an srs of all possible measurements from solution. they are also assumed to have a standard deviation of 0.2, a normal distributin, and a mean concentration equal to the true concentration of the solution. carry out a significance test to determine whether these six measurements provide reliable evidence that the true concentration of the solution is actually not 5 mg/dl.
