Sample questions
Plan an investigation to determine the effect of temperature on the rate of respiration in yeast. [6]
Yeast cells produce an enzyme called invertase. Invertase catalyses the breakdown of sucrose into reducing sugars. Sucrose is not a reducing sugar. A student investigated the effect of two different concentrations of invertase extract on a sucrose solution. The student used this…
A student investigated the effect of glucose concentration on the rate of anaerobic respiration in yeast. Anaerobic respiration in yeast breaks down glucose to form ethanol and carbon dioxide. Anaerobic respiration in yeast causes the blue dye, methylene blue, to become colourles…
