PLAY
The overall balanced equation that summarizes cellular respiration
6O^2 + C^6H^12O^6---> 6H^2O + 6CO^2
The molecule that organisms use for most energy
ATP
How is glucose taken into the cell?
Facilitated Diffusion
Glycolysis means
Sugar Breaking
Where in the cell does glycolysis take place?
Cytosol
Does glycolysis require oxygen?
No
What is produced during glycolysis?
2 Pyruvate, 2 ATP, 2 NADH
What happens to the pyruvate from glycolysis if no oxygen is available?
It is changed to lactic acid or ethyl alcohol and CO^2
What 3 main steps occur in the mitochondria?
1. Oxidation of pyruvic acid
2. Krebs cycle
3. Electron Transport Chain (followed by chemiosmosis)
What are the products of the Krebs Cycle?
NADH, FADH^2, ATP, CO^2
What do NADH and FADH^2 contain that are so important?
High energy electrons and Hydrogen
During which steps of aerobic respiration is CO^2 produced?
1. Oxidation of pyruvic acid
2. Krebs Cycle
What is the main purpose of the Krebs Cycle?
To produce the energy carrying compounds NADH, FADH^2, and ATP
What is the final electron acceptor in the ETC?
Oxygen
After the water accepts electrons what is produced?
Water
Where is the highest concentration of protons (H+) located in the mitochondrion?
In the inter membrane space
What is the ultimate purpose of moving electrons through the ETC?
To build a proton (H+) gradient necessary for ATP production
The energy in one NADH is enough to produce . . . ATP
3
The energy in one FADH^2 is enough to produce . . . ATP

3 examples of ATP work in a cell
1. Mechanical
2. Transport
3. Chemical
What enzyme is needed to produce ATP?
ATP synthase
