Cellular Respiration
What is the term used to describe the type of cellular respiration in which oxygen is not required?
Anaerobic Respiration
What step follows glycolysis?
The Prep Step
What do we invest into oxidative phosphorylation?
A) NADH and FADH2
B) O2
C) H2O
D) A & B
E) All of the Above
D) A & B
Where does the citric acid cycle take place?
In the mitochondrial matrix
Where does prep step take place?
Mitochondria (mitochondrial matrix specifically)
The addition of electrons to another substance is called ______. The loss of electrons from another substance is called ______.
reduction, oxidation
Where does glycolysis take place?
Out in the cytoplasm
Where is the electron transport chain located?
In the cristae
What are the two electron carriers we end up with at the end of the citric acid cycle?
NADH and FADH
This has nothing to do with prep step, but I couldn't think of another question! What are the two other molecules that can be used to make ATP:
A) Fats and proteins
B) Water and fats
C) Potassium and Sodium
D) Proteins and Potassium
A) Fats and proteins
Which of the following uses lactic acid fermentation:
A) Hormones
B) Lungs
C) Muscles
D) None of the Above
C) Muscles
What does glycolysis start with?
Glucose and 2 ATP (this is the only step where we invest ATP to get the process to happen)
What do we end up with at the end of oxidative phosphorylation?
Where does the step following the citric acid cycle take place?
Electron Transport Chain
What do we invest into the prep step?
2 Pyruvates
How much ATP does aerobic cellular respiration yield in total?
36-38 ATP
What is NADH?
An electron carrier
The flow of hydrogen along its gradient releases energy to produce ______. Chemiosmosis is the flow and production of this substance.
ATP
Aside from the electron carriers, what are the other two things we end up with at the end of the citric acid cycle?
ATP and CO2
What do we end up with at the end of Prep Step. CO2, NADH and ____ _____.
Acetyl coenzyme A (Acetyl CoA)
What is the formula for cellular respiration?
C6H12O6 + 6O2 ---> 6CO2 + 6H2O + Energy
What do we end up with at the end of glycolysis?
2 pyruvates, 2 ATP (net 2 ATP, we get 4, but we invested 2), 2 NADH
We can't just move hydrogen into the matrix (acidic), it has to bind. This is where a molecule comes in and works as the final acceptor in aerobic respiration. What is the name of this molecule?
O2 (oxygen)
What do we invest into the citric acid cycle?
2 acetyl CoA
Although this is not needed for the reactions, we cannot go past glycolysis/complete prep step without the presence of ____.
O2 (Oxygen)
