Starch Investigation

After the experiments we did in class, I came to the conclusion that when starch is in the mouth, enzymes in our saliva break it down and turn it into glucose.
My first piece of evidence comes from the investigation where we chewed a cracker with starch for two minutes. As we chewed, the cracker’s taste changed from bland to sweet. As we chewed, the enzymes in our saliva broke down the starch molecules, which caused them to rearrange and create a new product: glucose. My second piece of evidence comes from Reading 4.1, where we collected the evidence that when starch is broken down and mixed with water, it creates glucose. This reading also provided us with the information that saliva is made with water, salts, mucus, antigerm compounds, mouth cells, and …show more content…
I came to the conclusion that when starch molecules are in the mouth, enzymes in our saliva break it down and turn it into glucose. In the cracker investigation, the taste turned from a dull taste to a sweet taste as we chewed it. This was because the enzymes from our saliva broke the starch down, and the water from our saliva combined with the starch subunits to create glucose. From Reading 4.1, we collected the evidence that confirmed what we had learned; that when starch is broken down and mixed with water, glucose is created. Another piece of evidence we found was when the baby food became runny and loose when it was around the spoon that had saliva with enzymes and water in it. This shows that the enzymes helped to break down the molecules in baby food, and the water combined with those molecules. With the evidence we have collected, we are able to come to the conclusion that when starch molecules are in the mouth, enzymes from our saliva help break them down, and then the water from our saliva combines with the starch subunits to create
