What are the three steps of cellular respiration?
glycolysis, Krebs cycle, ETC
100
In what part of the cell does glycolysis take place?

cytoplasm

100

Is the Krebs cycle aerobic or anaerobic?

Aerobic

100

Where does the ETC occur?

On the membrane of the mitochondria
100
What type of fermentation does our body go through?
Lactic acid fermentation
200
Which step produces the MOST amount of ATP?
ETC
200
What happens to glucose during glycolysis?
It is split in half
200

For every 1 glucose, how many turns of the Krebs cycle do you need?

2 Krebs cycle per 1 glucose

200

What step is between glycolysis and Krebs cycle?

Pyruvate oxidation

200
What are the two types of fermentation?
Lactic acid and alcoholic
300

What types of organisms go through cellular respiration?

all organisms

300

Is glycolysis aerobic or anaerobic?

anaerobic

300

Which is the name of the coenzyme that attaches to acetyl?

coenzyme A

300

What protein is responsible for making ATP?

ATP synthase

300
What are the products of alcoholic fermentation?
ethanol (alcohol) and CO2
400

What are the two reactants of cellular respiration?

glucose and oxygen

400

What is the molecule called that glucose splits into?

pyruvic acid

400

What does acetyl-CoA become when it attaches to the 4-carbon oxaloacetate?

citric acid

400

About how many ATP molecules are produced if cellular respiration is successfully carried out?

36

400
What type of fermentation did the yeast go through in our lab?
alcoholic fermentation
500

What are the three products of cellular respiration?

carbon dioxide, water and ATP (energy)
500

Describe the ATP production of glycolysis

Glycolysis starts out using 2 ATP but makes 4 ATP with a net yield of 2 ATP

500

What are the products of the Krebs cycle?

2 carbon dioxide, 1 ATP, 3 NADH and 1 FADH2

500

What is the final electron acceptor on the ETC and what is produced by that acceptor?

oxygen accepts the electron and with hydrogen forms a water molecule.

500

If fermentation doesn't produce ATP, why do cells go through the process?

Fermentation converts NADH to NAD+ so glycolysis can continue to produce ATP
