This lab aims to study aerobic respiration and alcoholic fermentation through experiments with seeds and yeast. Students will measure oxygen consumption of germinating and ungerminated pea seeds over 60 minutes using a volumeter. They will also observe gas production from yeast fermenting glucose, starch, and starch treated with amylase. The document provides background on metabolism, respiration, ATP, aerobic respiration, and fermentation. It outlines the objectives, materials, procedures, and data table for the oxygen consumption experiment and fermentation demonstration.
