Avidin is a protein from egg white. It has very high affinity to biotin and because of that works as a highly specific inhibitor of biotin enzymes. Which of the following conversions would be blocked by the addition of avidin to a cell homogenate?

(a) Glucose → pyruvate

(b) Pyruvate → glucose

(c) Oxaloacetate → glucose

(d) Malate → oxaloacetate

(e) Pyruvate → oxaloacetate

(f) Glyceraldehyde 3-phosphate → fructose 1,6-bisphosphate

Amonoprotic acid is an acid that donates a single proton to the solution. suppose you have 0.140 g of a monoprotic acid dissolved in 35.0 ml of water. this solution is then neutralized with 14.5 ml of 0.110 m naoh. what is the molar mass of the acid?

1.aluminum chloride (alcl3), and sodium hydroxide (naoh) can react to form aluminum hydroxide (al(oh)3) and sodium chloride (nacl).    you have 13.4 g of aluminum chloride and 10.0 g of sodium hydroxide. answer the following questions: •what is the balanced equation for this reaction? •if you use all 13.4 g of aluminum chloride, how many grams of aluminum hydroxide can be formed? work must be shown to earn credit •if you use all 10.0 g of sodium hydroxide, how many grams of aluminum hydroxide can be formed? work must be shown to earn credit •how many grams of aluminum hydroxide will actually be made?     which reagent is limiting? explain your answer.
