Then a balloon is put over the test tube and the balloon inflates (but my balloon was … Be specific when describing each flask. You will use the following table to mix the proper amounts of water, yeast solution and corn syrup (a source of sugar) in small beakers. Balloon 1: Place a funnel into the opening of the balloon. FERMENTATION RATES FOR DIEFERENT CARBOHYDRATES Fermentation Rate (mL COx/min) Carbohydrate Type Adapted from: Reinking. The equation for yeast fermentation is: C6H12O6 ----> 2CH3CH2OH + 2CO2 (C6H12O6 is a sugar monomer, either glucose or fructose. a day ago. Why was it the control? 1. 2014 Introduction: Fermentation is a metabolic pathway that produce ATP molecules under anaerobic conditions (only undergoes glycolysis), NAD+ is used directly in glycolysis to form ATP molecules, which is not as efficient as cellular respiration because only … Pour 7g of yeast into each bottle. conditions and measure the production of one fermentation product – CO 2. Transfer this water into the conical flask with yeast and sugar ready. Learn vocabulary, terms, and more with flashcards, games, and other study tools.
