Question

1. Trace the path that electrons take in the ETC in mitochondria from the beginning to the end. Explain what happens to the electrons as they move through, and what processes take place. Mention molecules/proteins that are of significant relevance to this process.

2. a) Trace the path that electrons take in the ETC in chloroplasts from the beginning to the end. Explain what happens to the electrons as they move through, and what processes take place. Mention molecules/proteins that are of significant relevance to this process. Assume non-cyclic electron flow.
