The amount of CO 2 Post by klhjbh62604 » Tue Jan 15, 2013 1:51 am . I hypothesize that that Saccharomyces cerevisiae will grow best and produce the most CO2 at 30 degrees Celsius, then 50 degrees, and lastly, 4 degrees Celsius. Moderators: kgudger, bfinio, MadelineB, Moderators. Then as temperatures rose too high the enzymes denatured and could not catalyse the reaction.
The results from our experiment do not support my hypothesis that S. cerevisiae would grow best at 30 degrees Celsius but instead suggest that it releases the most CO2 at 50 degrees Celsius. Is yeast a living organism? Y is for Yeast Experiments. This experiment shows that carbon dioxide production from yeast increases with increased temperature, as the number of carbon dioxide bubbles increased as the temperature rose. This indicates that 35°C is in the optimal range of temperatures that maximize the metabolic rate of enzymes responsible for breaking down sugar in yeast. 9). This is an excellent opportunity for students to design their own experiments to determine which variables affect the yeast’s ability to produce CO 2.. Yeast is a fungal microorganism that feeds on sugar and produces carbon dioxide (CO 2) plus ethanol.As the yeast feeds on the sugar, it produces carbon dioxide gas. Aerobic respiration in yeast: Glucose + Oxygen =====> Carbon dioxide + Water Anaerobic respiration in yeast: Glucose =====> Ethanol and Carbon dioxide Both forms of respiration produce carbon dioxide as a waste product so… production in baker’s yeast (Saccharomyces cerevisiae) Hillary Janssens, Lisa Kim, Icel Lee, Melody Salehzadeh ABSTRACT We conducted an experiment to find the optimal temperature for cellular respiration of Saccharomyces cerevisiae. Glucose produced the most with a gas bubble of 132mm while sucrose yielded 102mm of carbon dioxide. Yeast is a single celled fungus that can respire aerobically when oxygen is available and anaerobically in the absence of oxygen. ... Yeast, sugar and CO2 production.

This experiment aims to investigate the relation between the temperature of the solution as an environment in which yeasts carry out aerobic respiration and the carbon dioxide production by yeasts.
Respirometers were incubated in water baths at temperatures of 25°C, 30°C and 35°C. The results show that the closest temperature out of the ones that were tested is 35°C. The different types of sugars used in fermentation had a significant impact on the amount of carbon dioxide produced. Ask an Expert: Yeast, sugar and CO2 production.

The A to Z Science series for toddlers and preschoolers at Inspiration Laboratories continues with the letter Y. Y is for Yeast Experiments. Questions to ask to get our yeast experiment going: What makes bread rise? Students use yeast to explore CO 2 production by living organisms..

Hello gbailey00: ... it produces a lot less carbon dioxide in the same amount of time that the yeast/flour mixture can. Name: Da Eun Kim Partners: Charles and Eileen Date of experiment: Oct 20th, 2010 Yeast Experiment Aim: To find how much gas is produced whe… Slideshare uses cookies to improve functionality and performance, and to provide you with relevant advertising. This was observed when two 1.5 L bottles each containing 7 g dry yeast+100 g sugar+1 L water were used for the production of yeast-produced CO 2 and when one 25 L container with 70 g of dry yeast, 1 kg of sugar and 10 L of tap water was used (P = 0.007, n = 278 respectively P < 0.001, n = 371).
