Uses 1 ATP/pyruvate for active transport ACETYL CO-A CHARGING (B-vitamin coenzyme) Co enzyme A receives carbons from pyruvate feeds them into Krebs cycle Enzyme removes CO 2 from pyruvate producing Acetyl CoA Each glucose produces 2 C0 2 + 2 NADH KREBS (CITRIC ACID) CYCLE Releases 6 original carbons in glucose as 6 CO 2 ; Stores energy in NADH/FADH 2 Occurs in Mitochondrial MATRIX OAA (oxaloacetic acid) receives 2 carbons from Acetyl CoA to make CITRIC ACID Each glucose requires TWO turns of cycle 1 GLUCOSE produces: 6 CO 2 , 2 FADH 2 , 2 ATP, 8 NADH

ELECTRON TRANSPORT- stage that produces the MOST ATP Attached to CRISTAE inner membrane Uses energy from NADH & FADH 2 to create proton gradient and make ATP Includes: THREE transmembrane PROTON PUMPS; Carrier molecules between pumps = UBIQUINONE (Q); and CYTOCHROMES Each NADH makes 3 ATP (drops its electrons at top of ETC; hits all 3 proton pumps) Each FADH 2 makes 2 ATP (drops its electrons at Q; skips 1 st proton pump; so makes less ATP) Electrons passing down ETC provide energy for pumping H +

    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.
