A Reese's Buttercup was tested to identify its macronutrients. Starch was present as indicated by a black color change with iodine solution. Glucose was present as shown by a yellow color change with Benedict's solution. Protein was detected turning the solution blue with Buret A and Buret B. Fat was also identified by transparency on filter paper.

6. Food Test
First I mushed the reese’s cup in a pestle and mortar, and then put it in 3 separate test tubes.
In the 1st test tube I put Iodine solution and water in it and left it for while to give it time to stick to the starch. It
turned black which meant starch was present.
In the 2nd test tube I put some of the mushed reese’s in it. I then added some water so the food could mix. After that
I added 10 drops of Benedict solution. If it turned yellow that meant glucose was present.
In the 3rd test tube I put some more mushed food in the test tube and added 1 drop of Buret A and Buret B. If the
food turns blue then it has protein.
First I get a piece of filter paper and then get a piece of my food. I then rubbed my food on the filter paper, if it
turned transparent it meant fat was present.

7. In the mouth saliva is produced. Saliva contains an amylase which starts to break down
starch particles into glucose.
Your saliva contains mucus which helps small pieces of food go down your gullet.

9. First the stomach juices are mixed with the food. Then the food
passes through to the duodenum.

passes through to the duodenum.

11. The enzymes in the Duodenum complete the process of breaking starch into
glucose. Bile then breaks down the fat particles. Then enzymes break down
the fat particles even further.

glucose. Bile then breaks down the fat particles. Then enzymes break down
the fat particles even further.

13. In the Ileum, sugars are in very small particles that are ready to be absorbed.
They are absorbed and transported all around the body to give you energy.
They are absorbed by microscopic things called villi which line the inner
surface of the ileum. What’s left behind is waste and water.

15. This is where all the water from the waste is absorbed into
the body.

16. Colon
This is where all the water from the waste is absorbed into
the body.

17. What’s left is the waste which cannot be digested. When it’s
ready, it is let through the anus and out of the body.
