Question

a device that can be used to measure the rate of exchange of oxygen and carbon dioxide during energy - acquiring pathways is called a
multiple choice
graduated cylinder.
barometer.
respirometer.
spectrophotometer.
fermentation tube.

Explanation:

A respirometer is a device used to measure the rate of gas exchange (such as oxygen uptake and carbon dioxide release) during energy - acquiring pathways like respiration. A fermentation tube is mainly used for fermentation processes (anaerobic in many cases) and not for measuring gas exchange rates in the context of energy - acquiring pathways like respiration. A spectrophotometer measures light absorption or transmission and is not related to gas exchange measurement. A barometer measures atmospheric pressure. A graduated cylinder is used for measuring the volume of liquids.

Answer:

respirometer
