References | PAGE | 1.0 Introduction Respiration usually occurs in two ways‚ aerobically and anaerobically. Aerobic respiration uses oxygen to function and anaerobic respiration functions without oxygen. Generally‚ anaerobic respiration starts by breaking down the molecules of glucose and produces pyruvic acid. The pyruvic acid then undergoes fermentation to produce ATP‚ the basic energy source in our human body. Although this kind of respiration is less efficient in producing energy‚ because

Goldfish Respiration Abstract The purpose of this experiment is to tests the effects of temperature on the respiration (breathing) rate of goldfish. In order to determine the goldfish respiration change adding small amounts of crushed ice to the water‚ than behavior will be noted. Then‚ the goldfish will experience the same experiment four more times and be noted again. This experiment will be conducted with four students‚ one goldfish‚ a 250 mL and a 150 mL beaker‚ thermometer‚ crushed ice‚

If the yeasts metabolism was slowed down‚ the product would stop rising. This could be done by using the variables‚ light and temperature. Both of these variables would affect the product from rising. 5. Time could have erred and the placement of the tubes into each other. If different tubes were used that fitted closer together would have improved

ABSTRACT The effect of co-factor (MgSO₄) and the nature of substrate on the rate of cellular respiration in yeast were determined using two different set-ups. In the first set-up‚ two test tubes were used where one contains 7m and the other with 7 mL 0.2M MgSO₄ and both containing 7mL 10% yeast suspension. Here‚ data shows that the H₂O mixture showed higher amount of CO₂ evolved than MgSO₄. In the second set-up‚ six Smith fermentation tubes were used each containing different 15mL solution (starch

Cellular Respiration Lab Report Wednesday 8:00 A.M. Lab March 2nd‚ 2005 I. Introduction In this lab we are measuring the amount of oxygen used in both germinating and non germinating peas. We are measuring the oxygen consumption by taking a reading of a respirometer submerged in two water baths. The first bath will be cold water and the second warm to determine the effect of temperatures on oxygen consumption. Our negative control will be glass beads to measure to increase or decrease

Lab 04: Sugar Respiration in Yeast Sugars are vital to all living organisms. The eukaryotic fungi‚ yeast‚ have the ability to use some‚ but not all sugars as a food source by metabolizing sugar in two ways‚ aerobically‚ with the aid of oxygen‚ or anaerobically‚ without oxygen. The decomposition reaction that takes place when yeast breaks down the hydrocarbon molecules is called cell respiration. As the aerobic respiration breaks down glucose to form viable ATP‚ oxygen gas is consumed and carbon
