Metabolism Revision Quiz

1)____is the central pathway in the​ 2)____ of all carbohydrates.

• 1) Glycolysis

  2) catabolism

• 1) Gluconeogenesis

  2) catabolism

• 1) Glycolysis

  2) anabolism

• 1) Gluconeogenesis

  2) ananbolism

Which of the following are macronutrients?

• Fats

• Vitamin B

• Carbohydrates

• Iron

• Protein

How many stages are found in the catabolic process?

• 4

• 2

• 1

• 3

Answer explanation

In stage 1 of catabolism dietary macromolecules (carbohydrates, lipids and proteins) are broken down into fuel molecules (e.g. glucose, fatty acids and glycerol). In stage 2 they are transformed into metabolic intermediates (e.g. pyruvate, acetyl-CoA). Stage 3 is the tricarboxylic acid (TCA) or Krebs cycle during which acetyl CoA is converted into CO2. Stage 4 is electron transport and ATP synthesis (oxidative phosphorylation).
