Cellular Respiration Flashcards
What is the equation of Cellular Respiration?
C6H12O6 + 6O2 → 6CO2 + 6H2O + Energy
The Mitochondria has __ parts in total
5
What are the parts of the Mitochondria, starting from the outside?
Outer Membrane, Inter-membrane Space, Inner Membrane, Cristae, Matrix
What is a Cristae?
It is a fold of the Inner Membrane
What is the Matrix?
It is the fluid inside the Inner Membrane
What is the First Step of Aerobic Respiration?
Glycolysis
Where does Glycolysis occur?
It occurs in the cytoplasm
Is Glycolysis anaerobic or aerobic?
It is an anaerobic process
What is the point of Glycolysis?
It breaks down one glucose (6C) into 2 (3C) pyruvic acid
How many ATP does Glycolysis use?
2 ATP
How many ATP does Glycolysis make in total?
4 ATP
What is the net gain of ATPs in Glycolysis?
2 ATPs
What are the Energy Products of Glycolysis?
2 ATPs and 2NADH
Where does the 2NADH from Glycolysis go to next?
To the ETC
What comes after Glycolysis in Aerobic Respiration?
The Intermediate Step
Where does the Intermediate Step occur?
In the Matrix
What is the end product of the Intermediate Step?
2 Acetyl-CoA (2C)
How do we arrive at the end product of the Intermediate Step?
The 2 Pyruvic Acid (3C) releases 2 CO2 and combines with CoA
What is the energy product of the Intermediate Step?
2NADH
What is a waste product of the Intermediate Step?
2CO2
What comes after the Intermediate Step?
The Krebs Cycle
Where does the Krebs Cycle occur?
In the Matrix
What does the Krebs Cycle begin with?
2 Acetyl-CoA (2C)
What is the main point of the Citric Acid Cycle?
It releases CoA (2C) and combines with 4C to make Citric Acid (6C)
What does the Krebs Cycle end with?
4CO2, 2ATP, 6NADH, 2FADH2
What is the last step of Aerobic Respiration?
Electron Transport Chain
Where does the ETC occur?
Inner Membrane of Mitochondria
What is the main point of the ETC?
To produce ATP
What brings in H+/e+ to use in the ETC?
FADH2 and NADH
What happens to the H+ in the ETC?
Chemiosmosis that powers Phosphorylation
1 NADH produces __ ATP
3
1 FADH2 produces __ ATP
2
Summarize Glycolysis
Glycolysis –> 6C from glucose breaks into 2 pyruvate (3C), making 2 ATP and 2 NADH
Summarize the Intermediate Step
Intermediate Step –> Turning 2 Pyruvate (3C) into 2 Acetyl-CoA, making 2CO2 and 2NADH
Summarize the Krebs Cycle
Krebs Cycle –> 2 Acetyl-CoA turns into 2 Acetyl (2C)+ 2 Citric Acid (4C), makes 4CO2, 6NADH, 2FADH, 2 ATP
Summarize the ETC
E- fuels H+ pump, Chemiosmosis occurs through ATP Synthase
