• glucose

• lactic acid

• ketone bodies

• amino acids

• the recycling of lactic acid produced by anaerobic glycolysis back into glycose by the liver.

• the way your grand mother cooks her favorite pies

• the extinction of the dinosaurs

• the QAnon conspiracy

Which compound is used as fuel in case of extreme starvation? (this fuel would never be used in normal condition)

• glucose

• fatty acid

• VFA

• amino acids

What is the opposite reaction of beta oxidation of fatty acids?

• lipogenesis

• trick or treating

What tissue ONLY use glucose as a fuel?

• Brain

• Muscle

• Liver

• Erythrocytes (RBC)

• Heart

Answer explanation

RBC do not have mitochondria..therefore, the only ruled they can use is glucose and they use it exclusively anaerobically.
