Round Robin-- Krebs, & ETC. Chpt. 9
- Goal of krebs cycle is breaking down the acetyl CoA and having the NADH + H+ and the FADH2 to go to the ETC with electrons
- In order for pyruvate to move into the mitochondrial matrix to be broken down/oxidized.. What molecule has to be present? :: Oxygen
- Pyruvate must move through what two membranes to get to the mitochondrial matrix? :: Outer membrane and inner membrane of the mitochondria
- Pyruvate has to get oxidized… what molecule does that :: NAD+
- What is the name of the step prior to Kebs cycle/citric acid cycle :: Link reaction/transition step
- What is the product of the transition step : Acetyl Coenzyme A (CoA)
- How many acetyl coA molecules will go into Krebs Cycle after transition step :: 1 (This process is happening twice, once for every pyruvate molecule or said differently, twice for every glucose molecule)
- Another name for Pyruvate? :: Pyruvic acid
- 2 Acetyl CoA interacts with what molecule when it enters the Krebs Cycle? :: Oxaloacetate
- When Acetyl CoA interacts with Oxaloacetate a byproduct is produced that can and goes back to link reaction. What is this molecule? :: CoA
- Another name for the Krebs Cycle is..? :: Citric Acid Cycle
- What molecules do we get to help rearrange the Oxaloacetate? :: NAD+ and FAD. Both are oxidizing agents.
- What is the energy that is produced in the Krebs Cycle? :: 2 ATP
- After electrons are obtained by NADH + H+ and FADH2 in the Krebs Cycle, where do they go? :: Electron Transport Chain (ETC)
- ETC :: Electron Transport Chain
- How many ATP is made with every FADH2 molecule? :: 2 ATP
- How many ATP is made with every NADH + H+ molecule? :: 3 ATP
- What is the name of the mobile proteins used in the ETC? :: Cyt C (Cytochrome C) and Q (Coenzyme Q)
- 3 proton pumps in ETC
- Where do the protons/ Hydrogen ions collect? :: The intermembrane space
- What is the goal of the ETC? :: to get H+ ions (protons) to the gradient The goal of the ETC is to make the Hydrogen ion gradient.
- Total CO2 of link reaction and krebs cycle :: 6 CO2
- Protons pass through ATP synthase (enzyme) to make ATP in :: Chemiosmosis
