Krebs Cycle

What is another name for the Krebs Cycle?

Citric Acid Cycle

Where does the Krebs Cycle take place?

Mitochondrial Matrix(only accept this answer)

What goes into the Krebs Cycle and what comes out? (Exclude ATP and electron carriers)

Acetyl CoA goes in and CO2 comes out.

How many times does the Krebs Cycle function for every molecule of glucose going into glycolysis?

Two times

What are the two electron carriers in the krebs cycle in both their uncharged and charged forms?

NAD+, NADH, FAD, and FADH2

What is the net output in terms of electron carriers and ATP for the Krebs Cycle only(not including pyruvate oxidation?

2 ATP, 6 NADH, and 2 FADH2

What is the significance of the electron carriers in the Krebs Cycle?

They are used in the electron transport chain to create large amounts of ATP.

What type of phosphorylation occurs in the Krebs Cycle?

Substrate level phosphorylation.

What is different about the Krebs Cycle in plants and animals?

In plants it occurs in cytosol and in animals it occurs in mitochondria

What does Acetyl CoA combine with in the beginning of the Krebs Cycle?

oxaloacetic acid

After combining with a carbon compound in the beginning of the Krebs Cycle, what does Acetyl CoA become?

Citric Acid

How much carbon dioxide is released for every glucose molecule entering glycolysis and completing the krebs cycle?

4

What is the compound reused every time the krebs cycle completes a cycle?

oxaloacetic acid

Which is not one of the products of the Krebs Cycle: NADH, FADH2, NADPH, or ATP?

NADPH

Where do the electron carriers that are produced in Krebs Cycle go?

Electron transport chain

NAD+ is reduced to form NADH, what does this mean? Endergonic or Exergonic

Electrons are gained or H is added. Endergonic

What does anaerobic and aerobic mean? What kind of a process if the Krebs Cycle?

Anaerobic does not use O2 while aerobic does. Kerbs is aerobic

ow many steps does the krebs cycle consist of for one cycle?

8

Did this process evolve earlier or later than glycolysis?

Later

How many carbons are in acetyl CoA?

2
