Cell Respiration (O2)

Figure from experiment 14B from Agricultural Science with Vernier

Introduction

Cell respiration refers to the process of converting the chemical energy of organic molecules into a form immediately usable by organisms. Glucose may be oxidized completely if sufficient oxygen is available according to the following equation:

C6H12O6 + 6O2(g) → 6 H2O + 6 CO2(g) + energy

All organisms, including plants and animals, oxidize glucose for energy. Often, this energy is used to convert ADP and phosphate into ATP. Peas undergo cell respiration during germination. Do peas undergo cell respiration before germination? Using your collected data, you will be able to answer the question regarding respiration and non-germinating peas.

Objectives

In this experiment, you will

  • Measure gas production.
  • Study the effect of temperature on cell respiration.
  • Determine whether germinating peas and non-germinating peas respire.
  • Compare the rates of cell respiration in germinating and non-germinating peas.

Sensors and Equipment

This experiment features the following Vernier sensors and equipment.
