Worked Solution & Example Answer:The carrier molecules represented in the diagram on page 10 are A - VCE - SSCE Biology - Question 15 - 2022 - Paper 1
Step 1
Identify the Carrier Molecules
Answer
The question asks about the carrier molecules depicted in a diagram referenced on page 10. Based on general knowledge of cellular metabolism, NADH and FADH<sub>2</sub> are well-known electron carriers involved in the Krebs cycle and oxidative phosphorylation.
Step 2
Evaluate the Options
Answer
A. NAD<sup>+</sup> and water - Incorrect, as NAD<sup>+</sup> is not a reduced form like NADH. B. FAD<sup>+</sup> and oxygen - Incorrect, as oxygen is not a carrier molecule itself. C. NADH and FADH<sub>2</sub> - Correct, as both are carriers of electrons. D. NAD<sup>+</sup>, carbon dioxide and FADH<sub>2</sub> - Incorrect, as NAD<sup>+</sup> is not the relevant form here, and carbon dioxide is not a carrier.
