Metabolism Chamber - ME-6936

ME6936_MAIN.jpg

Overview

The Metabolism Chamber is a 250 mL sample bottle with 2 holes cut specifically for PASCO gas sensors to allow simultaneous measurements of carbon dioxide gas and oxygen gas.

One of the most popular methods to explore cellular respiration in the biology lab is to measure the production of carbon dioxide by germinating seeds using a carbon dioxide sensor. The study of cellular respiration becomes richer when students simultaneously obtain carbon dioxide gas data and oxygen gas data.

How It Works

Germinating peas are placed in the Metabolism Chamber at room temperature. Students use PASCO sensors to collect measurements of COgas and O2 gas in the chamber (and possibly temperature as well) over time to see how they vary.

Students should also use non germinating (dry) seeds as a control and can vary the temperature of the seeds (slight heating or chilling) to note the effects on metabolism.
