KREBS CYCLE

Where does the Krebs cycle take place

• inner mitochondrial membrane

• mitochondrial matrix

• cytoplasm

• ribosome

The product of Krebs Cycle is (more than one answer)

• ATP

• NADH

• CO2

• FADH2

• PYRUVATE

How many times does the Krebs cycle happen per glucose molecule?

• 1

• 4

• 2

• 3

What is the first step of the Krebs cycle?

• CO2 is released from a five carbon compound to form a four carbon compound

• Acetyl CoA adds its two carbon acetyl group to oxaloacetate,producing citrate

• Acetyl CoA adds its three carbon acetyl group to oxaloacetate,producing citrate

• Acetyl CoA adds its one group to oxaloacetate,producing citrate

The number of ATP molecules produced by the Krebs Cycle one glucose molecule is

• 2

• 3

• 5

• 8

What is produced during the decarboxylation steps of the Krebs cycle?

• CO2

• NADH

• hydrogen

• water
