Parietal cell

Compared to other cells, the Parietal cell is relatively larger than other cells and have secretory canaliculi, more mitochondria, and cytoplasmic tubulovesicles. These cells are located in the inside lining of the stomach, the category the cell falls under is epithelial. The function of the Parietal cell is to produce large quantities of acid at high concentrations, for it is used to break down food in the stomach, it also releases enzymes that regulate receptors on the cell to control the amount of acid secreted and when the acid should be secreted.

Lab of Sweets

During the lab, my partners and I, put different types of sugar (Sucrose, Glucose, Fructose, Glactose, Maltose, Lactose, Starch, and Cellulose) in separate boxed off sections of a paper towel, one by one tasting each of them and rating how sweet they tasted to us. There was a relation between structure and the taste of the sugar, the more complex the structure, the worse it tasted. I can relate some of these sugars to some fruit that I have eaten and more or less, a few sweets, candy.
