Cell Respiration


What are the 2 types of Catabolic Reactions which yield ATP? 1. Substrate Phosphorylation 2. Oxidative Phosphorylation
What is Substrate Phosphorylation? DIRECT ATP formation - w/o O2
How does Substrate Phosphorylation make ATP? by removing a PO4 from Substrate + ADP = ATP - 1 step
Where does Substrate Phosphorylation occur? throughout the Cytoplasm
What is Oxidative Phosphorylation? INDIRECT ATP formation
How does Oxidative Phosphorylation work? Coenzymes NAD and FAD accept H+ from substrates --> pass electrons through ETS - 2 step
Where does Oxidative Phosphorylation take place? concludes in the Mitochondria
What role does O2 play in Oxidative Phosphorylation? final e- (H+) acceptor
What are Cyotchromes? small, Iron-containing Proteins
Where are Cytochomes located? arranged side-by-side along the INNER Mitochondrial Membrane
How many Cytochromes does the average cell have? some 24, some 12, some 0 - depending on cell's need/ability to produce ATP
What are 2 differenced between NAD and FAD? NAD: yields 3 ATP, accepts 2 H+; FAD yields 2 ATP, accepts H Atoms
What would happen if there were no O2 at the end of ETS? entire process would back up --> no ATP --> death
How many electrons can each Cytochorme hold at 1 time? 1 - they play "hot potato"
How do NAD and FAD move into/out of the ETS? Passive Diffusion: HIGH --> LOW

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.
