biology

Atoms are the building blocks of matter. protons, neutrons & electrons make up a atom. An element is a pure substance that cannot be broken down. There are over 100 known elements. A compound ia a pure substance formed by two or more elements. There are MILLIONS of known compunds and thousands more discovered each year.

Most cells store small carbon compounds that serve as building blocks for large molecules. Macromolecules are large molecules formed by joining smaller organic molecules together. Polymers are molecules made from repeating units of identical or nearly identical compounds are called monomers that are linked together by a series of covalent bonds.

A chemical reaction is the process by which atoms or groups of atoms in substances are reorganized into different substances. A chemical equation shows the reactants in the starting substances & the products are the substances formed during the reaction. The reactants that bind to the enzyme are called substracts.

A chemical reaction is the process by which atoms or a groups of atoms in substances are reorganized into different substances. Chemical bonds are broken and/or formed during a chemical reaction. A chemical equation shows the reactants at the starting substances and the products form during the reaction.

Molecules that have an unequal distribution of charges are called polar molecules. This mean is has opposite charges. In water, the electrostatic attraction is called a hydrogen bond. This is weak interaction involving a hydrogen atom, oxygen or nitrogen atom.

In unit 6 I learned that there are a lot of different elements. Protons, neutrons & electrons make up an atom. I also learned that Most cells store small carbon compounds, but what got to me the most was that chemical bonds have to be broken down to make an reaction
