What is the Citric Acid Cycle?
*will also accept Krebs Cycle*
100
This is the fourth stage of cellular respiration.
What is oxidative phosphorylation?
100
How many H+ ions are needed to "rotate" ATP synthase?
What are 3?
200
The first stage of cellular respiration converts one molecule of *blank* to two molecules of *blank*.
What are glucose and pyruvate?
200
This is where pyruvate is broken down.
What is the mitochondrial matrix?
200
The Citric Acid Cycle is a type of this cycle, in which particular molecules enter the cycle while others leave.
What is a metabolic cycle?
200
These are oxidized in O.P. and this is made by phosphorylation.
What are NADH and FADH2, and ATP.
200
This man "discovered" the Citric Acid Cycle.
Who is Hans Krebs?
300
Stage 1 has a net ATP production of...
What is 2?
300
This organic molecule is added to the acetyl group formed by the breakdown of pyruvate.
What is Coenzyme A (or CoA)?
300
In the first step of the citric acid cycle, the *blank* (with two carbons) is removed from acetyl CoA and attached to oxaloacetate (with four carbons) to form *blank* (with six carbons).
What are the acetyl group and citrate (citric acid)?
300
This enzyme synthesizes ATP.
What is ATP synthase?
300
This consists of a group of protein complexes and small organic molecules embedded in the inner mitochondrial membrane.
What is the electron transport chain (ETC)?
400
These steps of glycolysis result in the release of ATP molecules (asking for the step numbers).
What are steps 7 and 10?
400
How many carbon dioxide molecules are released and how many NADH molecules are formed during Stage 2 of cellular respiration?
What are 2 and 2?
400
These two things regulate the Citric Acid Cycle.
What are the availability of substrates and feedback inhibition?
400
This is the maximal amount of ATP that can be made by O.P. (per glucose).
What is 30-34 ATP molecules?
400
*blank* releases an electron to the ETC before *blank*.
What are NADH and FADH2?
500
Why is it necessary to have step 5 of glycolysis?
What is because fructose-1, 6 bisphosphate is asymmetrical and one "half" needs to be modified.
500
The acetyl group is attached to CoA via a covalent bond to this kind of atom.
What is a sulfur atom?
500
These are produced in the Citric Acid Cycle (per glucose):
? CO2
? ATP
? NADH
? FADH2
What are 4, 2, 6, 2?
500
ATP synthase is this kind of "machine".
What is a rotary machine?
500
Because hydrogen ions consist of protons, the H+ electrochemical gradient is also called this.
