Aerobic Respiration - Exercise #1 - Advanced
- Give the subunit composition for each of the cytochrome oxidases.
- How and which transcription factor(s) regulate expression of cytochrome bo oxidase and cytochrome bd-1 oxidase? What environmental factor(s) regulate gene expression?
- Name two substrates that can serve as electron donors to the cytochrome oxidases via the quinone pool? Name the enzymes that carry out the oxidation reactions.
- You decide to compare and contrast two electron transport chains both initiating from NDH-1. The electron transport chains differ in their terminal oxidase using either cytochrome bo oxidase or cytochrome bd-1 oxidase. Describe the similarities and differences you find. Explain why one creates more ATP.
