present. The reason that sugars were found and not starch‚ is because saliva contains an enzyme known as salivary amylase which catalyses the breakdown of starch to produce sugars such as maltose (Sherwood‚ 2013). When testing the effect of the salivary amylase concentration‚ we observed that the solution containing the most saliva (3ml)‚ become colourless faster than the solution which contained the least saliva (1ml). This proves that an increase in enzyme concentration (increase in saliva)‚ will cause

released. These are the most commonly made of recycled and/or natural organic materials. They utilize nature’s abundant supplies to create a replica or substitute for our plastics. One example would be the “Biodegradable plastic bags” made from the starch of the Cassava plant (Manihot esculent). The new plastic has been able to capture the interests of buyers‚ enabling it to advocate the benefits and obvious effects one can receive from using an eco-friendly product. To further elaborate the example
Premium Plastic Polymer Starch
Polymers can be made out of starch which is composed of long chains of glucose molecules. This study focuses mainly on making biodegradable plastics‚ which is certainly safer than non-biodegradable plastics‚ from potato starch. Biodegradable plastics made from raw materials are completely reusable and can be composted easily. Potato starch contains minimal protein and fat. Potato starch is a Polymer made of long chains of glucose units joined together. Potato starch contains two polymers: Amylopectin

I believe that the reason the cell appeared smaller after being exposed to starch solution was because water molecules move out of the cell because the concentration of water inside the cell was greater than outside the cell. I believe this for a few different reasons. We were given 3 different explanations to explain why the cells appear smaller after being exposed to sugar water. These include: That the sugar molecules are not able to enter the cell‚ but the sugar molecules push on the cell membrane

We found that‚ in acidic pH environment‚ the reaction rate of starch being broken down by alpha amylase is less than that of the reaction rate at a neutral and slightly basic pH environment. This finding partially supports our hypothesis. The spectrophotometer readings in our experiment measured the absorbance of 3-amino-5-nitrosalicylic acid‚ a colored molecule formed after dinitrosalicylic acid (DNSA) has reacted with the products of the enzymatic reaction or the simple sugars. Therefore‚ the absorbance

INTRODUCTION OF ENZYMES Enzymes are complex proteins that cause a specific chemical change in all parts of the body (David C. Dugdale‚ 2011). When we understand enzymes we understand cells (Marshall Brian‚ 2001). In many organisms most chemical reactions are catalyzed -when a substance speeds up the rate of a chemical reaction- by enzymes. Each enzyme controls a certain function that happens in a cell. Still each one has its own process and rate that it converts molecules. Studying enzymes shows how chemical

Abstract Enzymes are biological catalysts that speed up the rate of chemical reactions by lowering the reactants’ activation energy. The goal of this lab was conducted to determine the optimal temperature for bacterial and fungal Amylases and evaluate how temperature affects the catabolic rate of enzymes. Enzyme reaction rate was measured using an Iodine test in which drops of starch solution with either fungal or bacterial Amylase exposed to different temperatures were mixed with Iodine. Iodine

1. Cellulose‚ starch‚ and glycogen are very similar‚ yet very different. Describe the process by which each of these molecules is formed. Why does the subtle difference in how the simple sugar monomers are bonded in starch and cellulose affect how the two molecules are used? Cellulose is built from glucose molecules bonded covalently together through a process known as hydrolysis. Hydrolysis is a chemical process in which a molecule of water is added to a substance. Each alternating glucose
