Which condition can inhibit oxidative phosphorylation?
  1. High oxygen levels
  2. Low glucose levels
  3. Presence of cyanide
  4. High ATP levels

Questions & Step-by-Step Solutions

Which condition can inhibit oxidative phosphorylation?
  • Step 1: Understand what oxidative phosphorylation is. It is a process in cells that produces energy (ATP) using oxygen.
  • Step 2: Learn about the electron transport chain, which is a series of proteins in the cell's mitochondria that help in this process.
  • Step 3: Identify the different complexes in the electron transport chain. There are several, and Complex IV is one of them.
  • Step 4: Know that cyanide is a chemical that can affect the body. It is harmful and can block certain processes.
  • Step 5: Recognize that cyanide specifically inhibits Complex IV in the electron transport chain.
  • Step 6: Understand that by blocking Complex IV, cyanide stops the process of oxidative phosphorylation, preventing the production of energy.
