New cards

Which gas is produced as a result of alcohol fermentation by yeast?

carbon dioxide

2
New cards

A device that can be used to measure the rate of exchange of oxygen and carbon dioxide energy- acquiring pathways is called a _____

respirometer

3
New cards

How is a respirometer used to measure fermentation?

by the size of the gas bubble produced

4
New cards

Students conducted an experiment in which they set up respirometers that contained yeast and 2% glucose solution. Each respirometer was placed at a different temperature. The height of the bubble contained in the respirometer was measured every 5 minutes for 20 minutes.

What is the independent variable in this experiment?

temperature

<p>Respirometers were set up that contained yeast and either a solution containing a carbohydrate or distilled water. The height of the bubble contained in the respirometer was measured every 5 minutes for 20 minutes. The results can be seen in the graph below. </p><p>Which of the respirometers is the most likely to contain distilled water + yeast? </p>

<p>A student set up respirometers to measure fermentation of two different carbohydrates by yeast. She measured the height of the bubble (in mm) in each respirometer every 5 minutes for 20 minutes. Her data can be seen in the table below. </p><p>Which of the errors listed below could have caused these result? </p>

Which of the errors listed below could have caused these result?

She forgot to add the yeast.
