What are the functions of the high-energy electrons in the electron transport chain?(1 point)
Responses
They create ATP synthase.
They create ATP synthase.
They carry NADH and FADH2.
They carry NADH and FADH 2 .
They hold water bonds.
They hold water bonds.
They make ATP from ADP.
They make ATP from ADP.
The functions of high-energy electrons in the electron transport chain are:
1. They carry NADH and FADH2: High-energy electrons derived from NADH and FADH2 molecules are transferred along the electron transport chain. They provide the electrons needed for the chain to function effectively.
2. They create ATP synthase: As high-energy electrons are passed along the electron transport chain, the energy released is used to pump protons (H+) across the inner mitochondrial membrane. This creates an electrochemical gradient, which is then utilized by ATP synthase to drive the synthesis of ATP from ADP and inorganic phosphate.
Therefore, the correct answers are:
- They carry NADH and FADH2.
- They create ATP synthase.
