Question

multiple choice question
how does a respirometer measure fermentation?
o by determining the amount of atp produced
o by determining the size of the gas bubble produced
o by determining the amount of carbon dioxide in the atmosphere
o by determining the amount of glucose consumed
need help? review these concept resources.

Explanation:

Fermentation is an anaerobic process. A respirometer measures fermentation by detecting carbon dioxide production. In fermentation (e.g., alcoholic fermentation), carbon dioxide is a by - product. Measuring the amount of carbon dioxide in the atmosphere (trapped in the respirometer setup) helps quantify the rate of fermentation. Glucose consumption is not directly measured by a respirometer in the context of fermentation measurement as presented here. The size of gas bubbles is a less accurate and less commonly used method compared to measuring gas (carbon dioxide) amount. ATP production in fermentation (which is relatively low compared to aerobic respiration) is not typically measured by a basic respirometer setup for fermentation.

Answer:

By determining the amount of carbon dioxide in the atmosphere.
