Yeast is able to respire anaerobically. The box on the left contains the opening of a sentence. The boxes on the right contain several possible sentence endings. Draw three straight lines from the left box to the boxes on the right so that three correct sentences are formed. Beginning: Anaerobic respiration in yeast. Endings: decomposes nutrient molecules; counts as a chemical reaction; only happens in ribosomes; makes lactic acid; gives out less energy than aerobic respiration; needs oxygen.
State two biotechnology uses of anaerobic respiration in yeast.
The rate of gas production can be determined using the formula $\text{rate} = \frac{1}{\text{time}}$. Calculate the rate of gas production for the glucose solution concentration of 0.4 mol per dm$^3$. Give your answer to two decimal places.
