New cards
Breaking down the acetyl CoA and having the NADH + H+ and the FADH2 to go to the ETC with electrons is the goal of the
\
\
krebs cycle
2
New cards
In order for pyruvate to move into the mitochondrial matrix to be broken down/oxidized.. What molecule has to be present?
\
\
Oxygen
\
\
3
New cards
In order for pyruvate to move into the mitochondrial matrix to be broken down/oxidized.. What molecule has to be present?
\
\
Oxygen
4
New cards
Pyruvate has to get oxidized… what molecule does that
\
\
NAD+
5
New cards
What is the name of the step prior to Kebs cycle/citric acid cycle
Link reaction/transition step
\
\
6
New cards
What is the product of the transition step
\
\
Acetyl Coenzyme A (CoA)
7
New cards
How many acetyl coA molecules will go into Krebs Cycle after transition step (This process is happening twice, once for every pyruvate molecule or said differently, twice for every glucose molecule)
\
\
1
8
New cards
Another name for Pyruvate?
\
\
Pyruvic acid
9
New cards
2 Acetyl CoA interacts with what molecule when it enters the Krebs Cycle?
\
\
Oxaloacetate
10
New cards
When Acetyl CoA interacts with Oxaloacetate a byproduct is produced that can and goes back to link reaction. What is this molecule?
\
\
CoA
11
New cards
Another name for the Krebs Cycle is..?
Citric Acid Cycle
12
New cards
What molecules do we get to help rearrange the Oxaloacetate? Both are oxidizing agents.
NAD+ and FAD
13
New cards
What is the energy that is produced in the Krebs Cycle?
\
\
2 ATP
14
New cards
After electrons are obtained by NADH + H+ and FADH2 in the Krebs Cycle, where do they go?
etc
15
New cards
etc is the
electron transport chain
16
New cards
How many ATP is made with every FADH2 molecule?
2
17
New cards
How many ATP is made with every NADH + H+ molecule?
3
18
New cards
What are the names of the mobile proteins used in the ETC?
Cyt C (Cytochrome C) and Q (Coenzyme Q)
19
New cards
how many proton pumps (integral proteins) are in the etc?
3
20
New cards
Where do the protons/ Hydrogen ions collect?
The intermembrane space
21
New cards
What is the goal of the ETC (daily question answer)
to make an H+/proton gradient
22
New cards
Total CO2 of link reaction and krebs cycle
\
\
6 CO2
23
New cards
Protons pass through ATP synthase (enzyme) to make ATP in
Chemiosmosis
