Speeds up reaction in all living organisms - Not used up by the reaction—catalyst - Folded molecule with a “pocket” or active site where reaction occurs - Will end in “ase” Enzyme Rules - Very efficient - Very specific - Are catalysts 6. Label the a) activation energy ( energy of activation or E act ) on the energy curve (also called “hill”) below. 7. Draw on the curve above what happens to the energy of activation when an enzyme is used. 8. Define Potential Energy - Has the potential to do work - Stored energy Kinetic Energy - Does work - Energy in motion 9. Define ATP - Powers nearly all forms of work in the cell - Adenosine Triphosphate - Nucleic acid made of base and sugar and 3 phosphates E n e r g y

ADP - Energy for cellular work - Is like an uncharged battery that is low on energy 10. Name the molecule that acts as the immediate source of energy that drives all cellular work. - Catalyst OBJECTIVES FOR MODULE 6.2 CELLULAR RESPIRATION 1. Define the term cellular respiration . - A catabolic process of breaking down glucose to carbon dioxide and water, producing ATP - Fundamental function of cellular respiration is to generate ATP 2. Write the equation that summarizes cellular respiration. 3. Define NAD+ and say what role it plays in cellular respiration - Acts as a shuttle for electron and hydrogen atoms - Called an electron and hydrogen acceptor - Derived 4. For glycolysis, give The starting molecule: ________________ The ending molecule: __________________ The net number of ATP made per 1 glucose: ________ The number of NADH + H + molecules made per 1 glucose: ___________ Location in the cell: ___________________________ 5. For the bridging step plus citric acid cycle (Kreb’s cycle), give The starting molecule: ________________ The ending gas: __________________ The number of ATP made: ________ The number of NADH + H + molecules made: ___________ Location in the cell: __________________________

    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.
