Which statement best describes the analogy used to explain energy-yielding redox reactions?
Which statement best describes the analogy used to explain energy-yielding redox reactions?
- An electron donor is likened to an object at the bottom of a hill, which can gain energy as it moves to a higher energy state.
- An electron acceptor is likened to an object at the top of a hill, which can release energy as it moves to a lower energy state.
- An electron at a low energy state is likened to an object at the bottom of a hill, which can gain energy as it moves to a higher energy state.
- An electron at a high energy state is likened to an object at the top of a hill, which can release energy as it moves to a lower energy state. (correct)
What is the role of the electron acceptor in an energy-yielding redox reaction?
What is the role of the electron acceptor in an energy-yielding redox reaction?
- It donates electrons to the electron donor, facilitating the release of energy.
- It prevents the electron donor from releasing energy.
- It provides energy for the electron donor to release electrons.
- It accepts electrons from the electron donor, facilitating the release of energy. (correct)
What condition must be met for a redox reaction to release energy that can be harnessed by organisms?
What condition must be met for a redox reaction to release energy that can be harnessed by organisms?
- The $\Delta G$ of the electron donation must be negative, and the $\Delta G$ of the electron acceptance must be positive.
- The overall $\Delta G$ of the electron donation and acceptance must be positive.
- The overall $\Delta G$ of the electron donation and acceptance must be negative. (correct)
- The $\Delta G$ of the electron donation must be positive, and the $\Delta G$ of the electron acceptance must be negative.
