Principles of Biology

In this unit, it cleared up more than half of my diet misconceptions. Dieting isn't all about what you are eating, it's about what your body needs and how it will use the things you take in. You can eat all of the groups respectfully and will maintain a healthy weight. In class we broke down different things you put into your body and discussed what purpose they served and how your body responds to them. We also learned that our bodies are chalked full of different enzymes to break down most of the chemicals/ substances we put into our body. Weight gain is visible when you put in too much of what your body needs.

We, in class, split things into groups; starches, carbohydrates, sugars, and lipids. Starches are good for long term energy. The link goes in depth and tells the chemical formula and shows what are all considered starches. It also tells that they are made up of glucose monosaccharides bonded with glycosidic bonds.

Sugars are for short term energy and proving some beliefs aren't always bad for you. Many people have the common belief that they are all bad. Sugar in it's natural form and sugar from fruits are very good for your health. Broken down into groups;
Fructose= sugar from fruits.
Lactose= sugar from dairies.
Sucrose= your regular table sugar.
Sugar is a basic food carbohydrate and most commonly heard of by being found in honey and candy.

Carbohydrates
are played off as the bad guy as well, most commonly thought of when thinking about fat. Carbs actually transport energy, works in the immune system, and helps with blood clotting. If you eat the correct amount your body needs to sustain regular activity you will see no weight gain. What causes weight gain is when your body stores some much and doesn't need it and can't get rid of it. Carbs are most commonly found in breads, pastas, rices, and etc.

Proteins are made up of amino acids and you as well need these. They are vital in organisms and they participate in every process within the cell. Many are enzymes that create biochemical reactions and keep up your metabolism. Your metabolism is key in keeping down weight, it is how fast your body breaks down what your putting in.

Lipids are considered the natural occurring molecules such as fat, wax, oil, and vitamins A D E & K. They store energy and signal other molecules. Lipids have a subgroup for fats; Triglycerides and shouldn't be defined as fatty acids!

Virtual Classroom

Our work has certainly come a long way this year. In our short time working in this space (since only September 2009) we have attracted quite a bit of attention for our open approach to learning.  Your sharing, reflection and synthesis have earned two nominations for Edublogs awards in as many years.  Impressive is a good word.In the thread below, please reflect upon our use of free, open online tools to enhance our classroom this year. I'm always proud of how your work ends up being all about…See More

"since my question was a beast of a research topic i have decided to revise it a little. My real question is are humans evolving today, and if so then what is in store for us next"
