Basics of Chemistry for Biology

Why Study Chemistry in Biology? The physical and chemical laws that govern living systems are not different from those governing non-living systems. We study chemistry to better understand biology, we study physics to better understand chemistry. Reductionism. You are chemistry, change your chemistry and change who you are. Lab requires incubation time—set it up before lecture!

Element Element - a substance made entirely of one kind of atom. All matter consists of elements. Matter has volume and mass. 92 naturally occurring elements in one of three states: solid, gas, or liquid. And a 4 th , plasma. The difference between the three states is the amount of movement (energy) and distance between atoms. For example, water may be liquid, solid (ice) or gas (water vapor).

Example of Three States of Matter Water: Ice, Water, Vapor Each state, solid, liquid or gas, varies in density (distance between molecules) and energy (motion). Water is unusual because ice is less dense than liquid. Solid: Ice Liquid: Water Gas: Vapor

Chemical Symbols Each element is designated by a one or two letter chemical symbol (e.g. C=Carbon, Ca=Calcium, etc.).

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
