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.
