An 90 kg subject consumed a snack that contained 80 g of carbohydrate. Before eating the snack the subject’s blood glucose was 6.0 mmol.L-1. Calculate the concentration of glucose (mM) that would be reached in the blood after consuming the snack.Assume that all the carbohydrate in the snack was converted to glucose, rapidly absorbed and distributed throughout the extracellular water (ECW) within 30 minutes. Assume ECW is approximately 20% of body weight and the glucose is not metabolised further.
The equilibrium expression for any weak acid can be written as
HA (aq) + H20 (1) = A- (aq) + H;O+ (aq)
1. Write the K value expression based on the equation above (remember that pure liquids are not
included in the K expression). This is given the special symbol Ka.
2. In this experiment, you will be using pH to find [H3O+]. The relationship is [H3O*] = 10-PH .
For a pH of 7.4, find the [H3O+].
2. A reaction in the cell has a STANDARD Gibbs Free Energy of -200 kcal/mol.
Does this reaction need an enzyme to make sure it happens?
