Metabolism Metabolism: all the chemical reactions that occur in the body o 2 types of metabolic processes: 1. Catabolic: break down 2. Anabolic: build up Oxidation: chemical reaction where electrons move up and down energy levels Reduction: chemical reaction where electrons move up an energy level Enzymes: aka catalysts o 3 types of enzymes 1. Proteins 2. Substrate specific 3. Optimal pH and temperature o Apoenzyme: protein portion of an enzyme o Cofactor: nonprotein portion of an enzyme necessary for function o Holoenzyme: apoenzyme + cofactor/ functional enzyme o Coenzyme: small/ organic/ derived from vitamins/ used to transfer electrons 1. NAD+: Nicatinamide Adenine Dinucleotide 2. FAD: Flavin Adenine Dinucleotide Cellular respiration: process of using O2 to oxidize molecules to provide ATP Glucose Catabolism

    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.
