Chapter 3 : Cell Metabolism Flashcards
Aerobic Cellular Respiration Definition
Takes in sugar ( glucose) and breaks it down into carbon dioxide and water
—Produces energy in the form of ATP
Requires oxygen and produces carbon dioxide
Anaerobic Fermentation Definition
Does not require oxygen
ATP Synthase Definition
Is a transport protein and an enzyme
Metabolism Definition
Consists of all of the chemical
reactions that take place in a cell
Glycolysis Definition/Meaning
Occurs in the cytosol
Splits one glucose into two pyruvate molecules
—Creates 2 ATP, 2 NADH molecules, 2 Pyruvate
Does not require oxygen
Transition Reaction Definition/Meaning—
Occurs in the mitochondria
—Creates 2 CO2,2NADH,2 Acetyl
Citric Acid Cycle (Krebs Cycle) Definition/Meaning
Occurs in the mitochondria
Electron Transport Chain Definition/Meaning
Electrons of FADH2 and NADH are transferred from one protein to another until they reach oxygen
— Results in 32 ATP
(Requires oxygen)
Glycolysis
Starts with glucose
Ends with 2 ATP, 2 NADH , 2 Pyruvate
Transition Reaction
Starts with 2 pyruvate , 2 Coenzyme A
Ends with 2 CO2 , 2 NADH , 2 Acetyl CoA
Citric Acid Cycle
Starts with 2 Acetyl CoA
Ends with 4 CO2 , 2 ATP , 6 NADH and 2 FADH2
Which has a higher pH?
A. Extracellular space
(outside the cell)
B. Cytosol
C. Intramembrane space
of the mitochondrion
D. Lumen of the
mitochondrion
When the ETC transports H+ this is called:
A. Simple diffusion
B. Facilitated diffusion
C. Active transport
What gives the energy to the ETC to do the active
transport
A. ATP
B. GTP
C. e-
D. NADH
E. O2
The ETC transports H+ from where to where?
A. Intramembrane space
to cytosol
B. Cytosol to outside the
cell
C. Intramembrane space
to the lumen
D. Lumen to the
Intramembrane space
