Question

Inputs (raw materials) of the respiratory (electron transport) chain:

1. NADH molecules.
2.FADH2 molecules.
3. Oxygen molecules (O2).

Outputs (products) of the respiratory (electron transport) chain:

1. ATP molecules.
2. Water molecules (H2O).

Answer 1

The electron transport chain is a series of reactions that transfer electrons to oxygen to produce ATP. The inputs are NADH, FADH2, and oxygen, while the outputs are ATP and water.

Step-by-step explanation:

The electron transport chain, also known as the respiratory chain, is a series of oxidation-reduction reactions that transfers electrons to oxygen, ultimately reducing it to water. The inputs or raw materials of the electron transport chain include NADH molecules, FADH2 molecules, and oxygen molecules (O2). NADH forms 3 ATP molecules, while FADH2 forms 2 ATP molecules. The outputs or products of the electron transport chain are ATP molecules and water molecules (H2O).
