Krebs/ETC

The initial reaction of the Krebs cycle produces:

• Glucose and pyruvate

• H₂O and CO₂

• CO₂, acetyl-CoA, and NADH

• Coenzyme A and NADH

The waste product produced during the Krebs cycle is...

• Oxygen

• Water

• Carbon Dioxide

• ATP

True or False: The Krebs cycle anaerobic.

• True

• False

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

• 2

• 3

• 4

• 0

Krebs Cycle takes place in the:

• Cytoplasm

• Mitochondrial matrix

• Ribsome

• Intermembrane Space

Prior to entering the Krebs Cycle, each pyruvate molecule loses electrons, hydrogen ions, and a carbon, forming an energy-rich molecule of

• Acetyl-CoA
• Citrate
• Oxaloacetate
• Malate

NADH and FADH₂

• carry energy/electrons to the ETC.

• bind with Acetyl CoA.

• make pyruvic acid

• make water.

The Kreb's Cycle is also known as:

• The Pyruvic Cycle
• The Respirational Cycle
• The Citric Acid Cycle
• The Berk Cycle

How many turns of the Krebs cycle per glucose molecule?

• 1

• 2

• 3

• 4

WHich of these is not a product of Krebs

• H₂O

• CO₂

• NADH

• ATP
