1 10/04/10 1. Reminder: two ways to make ATP! 2. glycolysis (sugar splitting) overall process 3. Following the C’s & H’s in Krebs Cycle On Wednesday we will act out the electron transport system and make lots of ATP Do you have a bio study group? Invite me to come and answer questions sometime (rbuskirk@mail.utexas.edu) NAD and FAD are hydrogen atom shuttles (in redox reactions) between different parts of cellular respiration. 1. (review) Which reaction, A or B, can be coupled with this one, to move it forward? NOTE-these reactions are redox-coupled . C 4 H 6 O 4 --> C 4 H 4 O 4 (succinic acid) (fumaric acid) A. FAD --> FADH 2 B. FADH 2 --> FAD 2. (new) Is this reaction (C 4 H 6 O 4 -> C 4 H 4 O 4 ) A. endergonic? B. exergonic? in two general ways : (a) substrate-level phosphorylation (phosphate from a sugar substrate onto ADP) (b) oxidative phosphorylation (ATP synthase/membrane) (a separate phosphate ion added onto ADP) Explain the difference to the person next to you:
