Biochem
In this unit we learned that water is a polar molecule. What that means is that one of ends of the molecule is slightly positive and the other is slightly negative. One of the most familiar and common polar molecules on Earth is water. In water, two hydrogen atoms are bonded to one oxygen atom. The oxygen atom has a greater electronegativity than the hydrogen atoms and so receives a greater share of the molecule's shared electrons. This means that the hydrogen side is more positively charged than the oxygen side. Study Resources This website will explain what a polar molecule is and give examples of them that will give you further knowledge of what they are and what they do. When you click on this link it will take you a site that will tell you how enzymes work and why they are so needed in life to help us survive and their purpose. In this article by Science Matters, it will give examples of biomolecules and the element carbon. Biomolecules are compounds that center around the element, carbon. Carbon, because of its valence structure, is actually quite versatile and probably responsible for the great variation of life on this planet In this unit we learned about enzymes and its purpose and structure. Enzymes are shaped kind of like pac man. An enzyme has a very important purpose in the human body. They are protein molecules that are manufactured by all plant and animal cells. All cells require enzymes to survive and function. We also learned about macromolecules or monomers. Monomers are multiple polymers bonded together to make one big molecule. Another important thing we learned about was biomolecules. A biomolecule or biological molecule is any molecule that is present in living organisms, including large macromolecules such as proteins, carbohydrates, lipids, and nucleic acids. I actually really enjoyed this lesson. I enjoyed it because we learned about elements that we already knew about but went into further detail. For example, I knew that there were 2 hydrogen and 1 oxygen atoms in a water molecule. But thanks to this unit, I now know that it’s a polar molecule. I wouldve never known that if it werent for his unit. |
