What are the 4 parts of cellular respiration?

Glycolysis, Oxidation of Pyruvate, Krebs Cycle, Electron Transport Chain

100
Where does glycolysis happen?
In the cytoplasm.
100
Where does the Krebs Cycle take place?
In the mitochondrial matrix
100
Where does the Electron Transport Chain take place?
In the inner membrane of the mitochondria.
100
What are the 2 types of fermentation?
Lactic Acid and Alcoholic.
200
What is substrate-level phosphorylation?
A reaction in which a phosphate group is transferred from the substrate directly to ADP forming ATP.
200

What is the final electron acceptor of the ETC?  What is formed?

Oxygen gas is the final electron acceptor, Water is formed

200

What are the 2 main purposes of the Krebs Cycle 

Fully oxidize Acetyl-CoA & Reduce Electron Carriers

200
Does the Electron Transport Chain happen with or without oxygen?
With
200

What type of fermentation is not reversible? Why?

Alcohol Fermentation, loss of Carbon as carbon dioxide

300
What is the overall equation for cellular respiration?
C6H12O6 + 6O2 -> 6CO2 + 6H2O + ATP
300

Does glycolysis occur in the presence or absence of oxygen?

Both!

300
Does the Krebs Cycle happen with or without oxygen?
With.
300

What is the name of the membrane protein that helps protons pass through the inner mitochondrial membrane during oxidative phosphorylation and helps drive the production of ATP?

ATP Synthase

300

What type of fermentation is used by yeast? What are the products?

Alcohol, ethanol & CO2

400

Where in the plant cell would you have ATP Synthase?

Chloroplast & Mitochondria

400
What type of phosphorylation happens in glycolysis?
Substrate-level
400
What type of phosphorylation happens in the Krebs Cycle?
Substrate-level
400

What type of phosphorylation happens in the Electron Transport Chain? How does this happen?

Oxidative. Energy from the electrons causes hydrogen ions to move into the inner membrane space. Hydrogen ions move down their concentration gradient through ATP synthase and this powers the production of ATP.

400
What is the main function of lactic acid fermentation that occurs in muscle cells?
To produce more NAD+
500

Cellular respiration occurs in four steps or stages. In which steps or stages are the carbon atoms removed and released as carbon dioxide?

Pyruvate Oxidation & The Krebs Cycle.

500

What are the products of glycolysis? 

The products are 2 pyruvate molecules, 2 net ATP and 2 NADH molecules. 

500

What are the products of the Krebs Cycle for one molecule of glucose?

6 CO2, 2 ATP, 6NADH, 2FADH2

500

What is the role of NADH and FADH2 in the Electron Transport Chain? 

NADH and FADH2 drop off electrons and hydrogen ions at the ETC. 

500

How many net ATP molecules do you get from one molecule of glucose using anaerobic respiration? Aerobic respiration?
