1. 
Cellular respiration can be split up into four sequences. ­­­­­­­­­­­­­­­­­­­­­These sections are: -Glycolysis -Transition Reactions -Krebs Cycle or Citric Cycle -and __________________.
A.
NADH
B.
Electron Transport Chain
C.
ATP synthase
D.
Inorganic Phosphate
2. 
This process breaks down one molecule glucose into two molecules of NADH. Pyruvate molecules are than individually sent to the transition reactions. This process results in two products, H20 and NADH. Overall four ATP are made but its net gain is two ATP due to the fact that it uses two ATP in the process. What is the name of this process?
A.
Glycolysis
B.
Transition Reactions
C.
Krebs Cycle
D.
Electron Transport Chain
3. 
Where does the transition reaction occur?
A.
mitochondrial matrix
B.
cytoplasm
C.
nucleus
D.
golgi apparatus
4. 
This process produces NADH+H and FADH2. Pyruvate enters the Krebs Cycle then goes through a series of reactions and the final product is six NADH+H and two FADH2. These energy carriers are then sent to the electron transport chain. This process happens twice for every molecule of acetyl Co-A.
A.
pyruvate
B.
glycolysis
C.
transition reactions
D.
krebs cycle
5. 
The majority of ATP created in cellular respiration is generated through this process. NADH and FADH2 drop their electrons which then move providing power to pump hydrogen across the membrane from the matrix into the intermediate space. This creates a concentration gradient forcing the hydrogen through ATP synthase binding ADP with Pi ( inorganic Phosphate).
A.
pyruvate
B.
glycolysis
C.
transition reactions
D.
Electron Transport Chain
6. 
An enzyme bound to its cofactor is called:

A.
one
B.
two
C.

9. 
Glycogen is uniquely suited to the storage of carbohydrates in the liver because:
A.
its highly branched structure takes up more space
B.
its highly branched structure is more compact
