If a terminal electron acceptor (such as oxygen, sulfur, or a metal ion) is present, then cellular respiration will occur. Lastly Lactose just like sucrose is a disaccharide but in lactose it only produces on molecule useful in glycolysis, that being glucose the other molecule galactose cannot further be used in fermentation process. Also examining the final pHs of each of the sugars, glucose had a pH of 6.09, sucrose had a pH of 5.79 and lactose had a pH of 6.51, and this further proves that sucrose was the most efficient in producing ethanol through yeast fermentation. consumption

Place the Erlenmeyer flask under the clamp with the pH probe. Hay que medir voltaje, corriente y potencia en el lado del primario 3. Follow all standard laboratory safety procedures. Also sucrose will produce the most amounts of CO2, due to its molecular structure which contains a glucose and a fructose, then followed by glucose since it goes straight into the glycolysis, and last was lactose since it will take more time to break down the molecule into glucose and the other molecule produced, galactose, is a waste product. In this simulation, you will view animal and plant cells under a microscope, identify and label basic cell structures on micrograph images, and label cell structures on animal and plant cell diagrams.
