Organic molecules store energy in their arrangement of atoms (bonds) A cell breaks down these molecules to get energy with the help of enzymes This involves a series of oxidation- reduction reactions Oxidation is the loss of electrons Reduction is the gain of electrons (becomes more negative) OIL RIG oxidation is loss, reduction is gain

Enzymes are crucial in the transfer of electrons Coenzymes –a non-protein molecule required for some enzymes to function Act as electron carriers Take part in the oxidation/reduction rxns NADH NAD+ FADH 2 FAD

    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.
