Glucose and Cellular Respiration

evolved than MgSO₄. In the second set-up, six Smith fermentation tubes were used each containing different 15mL solution (starch, lactose, sucrose, glucose, fructose or distilled H₂O). the tubes were then added with 15 mL distilled H2O and 15 mL 10% yeast suspension. Here, results show that fructose had the highest rate of respiration followed by glucose, sucrose, lactose, starch and H₂O. Thus, simpler substrate would mean higher rate of respiration.

Insulin promotes the movement of glucose and other nutrients out of the blood and into cells. When blood glucose rises, insulin, released from the beta cells causes glucose to enter body cells to be used for energy. Also, it sometimes stimulates conversion of glucose to glycogen in the liver. Another pancreatic hormone, glucagon, promotes the movement of glucose into the blood when glucose levels are below normal. It causes the breakdown of stored liver glycogen to glucose, so that the sugar content of...

Yeast Fermentation lab

types of sugar being used in the experiment is glucose, sucrose, and lactose. Glucose is a monosaccharide and is used in the first step of glycolysis in order to help create pyruvates, which are then used to create ethanol as long as there is no mitochondria or oxygen present. Sucrose is a disaccharide, commonly referred to as sugar, it’s used worldwide, and mainly harvested from sugarcanes. Sucrose is composed of two monosaccharide’s being; glucose and fructose, both are used in glycolysis in order...
