Unit 2 Reflection

In this unit we learned about atoms which are made of protons which have a positive charge, neutrons which have no charge, a nucleus which is in the center of an atom, and electrons which are negatively charged. We also learned about how water is polar which means that it has an unequal distribution of charge between hydrogen and oxygen molecules, and how on a scale from zero to fourteen, seven is neutral, below seven is acidic, and above seven is basic. 

Later on in the unit we learned about the four macro molecules which include carbohydrates which are rings of carbon, hydrogen, and oxygen, lipids which are large molecules which contain long chains of carbon and hydrogen called fatty acids, proteins which are large molecules made of amino acids, and nucleic acids which are composed of thousands of nucleotides. In the last vodcast of the unit, we learned about the structures of enzymes and factors that affect enzymes which are pH and temperature. 

In this unit, learning the properties of water was the most difficult for me to learn out of all the lessons in the vodcasts that we learned in unit 2. Also from these experiences I learned how to work together with my classmates when we were doing labs, and how to successfully conduct and do a lab without having much knowledge of what you are supposed to do. I think that I am a better student than before because now I have more experience on what to do because of the things we did in class, and I learned new information that I didn't know until we learned it in class. 

I don't have anything that I want to know more about. One question I have is that are there other factors that could affect enzymes besides pH and temperature.
