As with just about everything else involving the human body, it is absolutely amazing that we can chow down on various things and somehow use this basic action to grow, move, breathe, and all other kinds of things. This article answers the question of how the human body turns food into useful energy.

This article was full of useful information when learning about engery and how our body uses it. What I found most helpful was the comparisons it used to make it more relatable and understandable to whoever is reading.

If you were absent the days your biology instructor talked about energy conversion in the body with ATP turning into ADP then this article is a must read for you. We as humans would not exist without air, water and food that takes matter and converts it into usable energy for our bodies to continue life processes. This simple article gives you the short but necessary explanation of how our amazing human bodies do this.

This article is a good read before reading about the processes of photosynthesis. The analogy of the pushing the boulder up the hill makes the concept easy to understand. The explanation of APT to ADP transformation is presented in a simple easy to understand format as well. Adding the explanation of how the Atkins diet is supposed to work in our bodies simply ‘adds the icing on the cake’ so to speak. This is an important article to read and a good start to understanding what happens when human eat.

The author ,Dr. Bill Robertson, has a talent for describing complex processes in a clear, concise manner. In this article he describes how the energy from foods is released so it may be used by the body. He begins with an analogy that illustrates the process, then dives deeper into the biochemical processes. I really enjoy reading these 101 articles such as this one. Even if I am very familiar with the topic, I generally think about the topic in a new light. Dr. Robertson's simple analogies are also a great tool to use when discussing these processes with students.

This article provides a brief summary of the process of turning food into energy with an easily relatable analogy for both teachers or students to understand. Gives good background information for teachers.
