Chemistry in Biology

Section 1: Atoms, Elements, and Compounds- On the periodic table, each element has a unique name and symbol.- Water is composed of hydrogen and oxygen.- Atoms of the same element that have different numbers of neutrons are called isotopes. - The half life of an element is the amount of time ot takes for half of a radioactive isotope to decay. - The two main types of chemical bonds are covalemt bonds and ionic bonds. McGraw Hill 2012 pgs 148-155

Section 4: The Building Blocks of Life - Carbon atoms can bond together in straight chais, branched chains, or rings. - Carbon is a component of almost all biological substances. McGraw Hill 2012 pgs 166- 171

Section 2: Chemical ReactionsActivation energy: the minimum amount of energy required for reactants to form products. Catalyst: substance that lowers energy needed to start a chemical reaction.Enzyme: protein that is a biological catalyst. Substrate: molecule that binds to an enzyme.McGraw Hill 2012 pgs 156-160.

Chemistry is the study of matter, its properties, how and why substances combine or separate to form other substances, and how substances interact with energy. http://www.livescience.com/45986-what-is-chemistry.html

Section 3: Water and Solutions- A mixture is a combination of two or more substances in which each substance retains its individual characteristics. - A suspension is a mixture that has a uniform composition throughout. - A mixture of sand and water is a heterogenous mixture. McGraw Hill 2012 pgs 161-165

    Your presentation made the information easy to understand. The information was condensed and simplified. The font choices were excellent and did not distract the audience but brought attention to the text. The pictures support the information and helps to visualize it. The video engaged the audience and was very interesting. What are the building blocks of life? What do they do? Why are they important?

    Thank you! Yours was great too. the building blocks of life are how carbon atoms bond together and form ring chains, branched chains, and straight chains. Carbon is a component of almost all biological substances.

    Your presentation was really easy to read and it had a lot of information. I liked that you put the periodic table of elements on it. Also, its good that you cited your work. You said that a mixture of sand and water is a heterogenous mixture but can you please explain what that is? Also, what are all of the biological substances? Thanks, and good job!

    Thank you! A biological substance is an infectious substance that is not in a form generally capable of causing permanent disability or life-threatening or fatal disease in otherwise healthy humans or animals when exposure to it occurs. https://www.ups.com/content/us/en/resources/ship/hazardous/responsible/diagnostic.html

    In heterogeneous mixture,the composition is not uniform throughout. Rather these consists of two or more parts which have different compositions. It has visible boundaries of separation between various constituents. eg: mixture of salt and sugar,mixture of sand and water,etc.
