Purpose: Many plants store their energy in the form of starch‚ a polysaccharide made from repeating units of the monosaccharide glucose. Our bodies break down starch into the individual glucose units‚ which are further metabolized into CO2 and water through the process of glycolysis—this is the process we commonly call digestion. The enzyme amylase is present in our saliva and begins the process of digestion when starch containing foods enter our mouths. In this lab you will measure the amount of

Sucrose Synthesis by D. DeWitt‚ PhD v1.5 11/10/12 Introduction | Condensation Reaction | Plant Synthesis | A. Introduction Although it might seem straight forward‚ the synthesis of sucrose‚ either as a simple condensation reaction (a.k.a. dehydration synthesis)‚ or what actually happens in plants is complicated. Before we explore sucrose’s creation‚ let’s take a look at its structure. In Figure 1‚ the space-filling model is pretty but rather useless at this point in our journey. We

living creatures‚ work together in a certain process that is crucial to existence: the formation of proteins. Although all species differ from each other in various ways‚ the processes by which proteins are synthesized are the same in all. Protein synthesis is a very complex process. In order to understand the process‚ there some basics that are essential for cells to create the proper proteins. DNA is a very long and double-stranded molecule that contains coding‚ through four nitrogen bases (adenine

there is no such thing as animal testing. One day your kid gets sick‚ deadly sick with smallpox‚ you take them to the hospital‚ they inject your kid with a bunch of random medicines to try and help but nothing helps. Your child later dies because there was no way to help‚ all of those doctor bills‚ useless injections‚ and the death of your child could have been avoided if there was animal testing to find the cure. Animal testing is needed in our world‚ we need animal testing to find cures for deadly

Should animals be used in medical research? The use of animals in laboratory research is a very well known debate. Many people wonder if the animals are treated well and if they are taken care of properly; however‚ if medical and scientifical experimentation were done in only human trials the knowledge and understanding of how drugs and procedures can affect human would be decades behind. That is why the use of animals in experimentation is a necessity in order to continue advancing medicine

Digestion begins in the mouth when one eats food. It begins the moment one takes a sandwich bite. The teeth are used to break the sandwich that contains lettuce and pickles into smaller particles or boluses so that the enzymes can digest the food much easier. Lettuce contains carbohydrates‚ proteins and fat. The tongue helps turn food in the mouth and mix with the saliva in the mouth which contains salivary amylase enzyme. It then passes through the esophagus to the stomach which is a mixer and grinder

cava has two part (branches)‚ these two parts are called the superior vena cava and the inferior vena cava. The superior vena cava returns blood from the neck and brain. The inferior vena cava returns blood from the rest of the body. The blood can only flow one way so there are 2 sets of valves which are between th atrium and the ventricles. These valves are called the right and left

The term metabolism is often used to indicate especially the breakdown of food and its transformation into energy. Although weight loss is a matter of sacrifice‚ the reality is that there is a bunch of ways to lose weight quickly. One is to increase metabolism which will help us gain the results so quickly. But how you can speed up metabolism? Big Question! But don’t worry. Here we show 6 ideas for you how to increase metabolism faster. 6 ways to increase metabolism/ foods that increase metabolism

Human Digestion Activity The digestive process involves the mixing of food‚ the movement of food through the digestive tract‚ and a chemical breakdown of large molecules of food into smaller molecules. The digestive system is made up of the digestive tract and other organs that aid in digestion. The digestive tract is a series of hollow organs joined in a long‚ twisting tube from the mouth to the anus. Those twisted tubes include the mouth‚ esophagus‚ stomach‚ small and

Some people think that animal testing is good and some people think it’s bad to have animal testing. Some people think that animal testing is bad because they are hurting innocent animals and some people think it’s good because instead of testing it on humans they will test it on animals to check if its safe and they are trying to figure out how to cure some diseases. Animals should not be used for a scientifical research they should not test on animals because it puts animals in danger‚ the next reason
