• Accepts hydrogen to form ethanol

• Accepts hydrogen to form lactate

• Forms acetyl CoA

What process occurs when pyruvate enters the mitochondria under aerobic conditions?

• Glycolysis

• The link reaction

• Fermentation

• Oxidative phosphorylation

What is removed from pyruvate during the link reaction?

• Water

• Phosphate group

• Hydrogen atom

• Carbon dioxide

What molecule is produced when pyruvate combines with Coenzyme A?

• Citrate

• Acetyl CoA

• Oxaloacetate

• FADH₂

Where does the Krebs cycle occur?

• Cytoplasm

• Inner mitochondrial membrane

• Mitochondrial matrix
