Question

Determination of Caloric Content of Three Foods1. Compare the calorimeter that you built to a bomb calorimeter. How are they similar and different?2. Although protein was part of the composition of the foods in this experiment, it was not the main macromolecule component of any of the foods. Why do you think a food consisting primarily of protein was omitted from these tests, based on what you learned about the way the fuel is "burned" in the body?

Answer 1

Answer:

The answers to both parts (1 and 2) are given below.

Explanation:

1. The calorimeter is similar to the bomb calorimeter in a way that both measure the changes in heat that occur as result of the chemical reaction taking place inside them. They are different in the sense that a bomb calorimeter provides an isolated system with constant volume and pressure, whereas a regular calorimeter allows pressure to equalize with the environment.

2. Carbohydrates are the molecules that break down and provides energy for cellular functions. Whereas, proteins are not meant for the production of energy but for the production of amino acids to function as structural units for protein synthesis. Simply, the breakdown of protein is for the synthesis of more proteins by providing several units of amino acids rather than the production of energy.
