Name two ironcontaining proteins involved in electron transport.

Answer

To answer the question "Name two iron-containing proteins involved in electron transport," we can follow these steps:

### Step 1: Understand the Context
Electron transport is a crucial process in cellular respiration, where electrons are transferred through a series of proteins to ultimately produce ATP. Iron-containing proteins play a significant role in this process.

### Step 2: Identify Iron-Containing Proteins
We need to identify proteins that contain iron and are involved in the electron transport chain.

### Step 3: List the Proteins
1. **Cytochromes**: These are redox-active proteins that contain heme groups with iron at their center. They are essential in the electron transport chain and facilitate the transfer of electrons.

2. **Ferredoxins**: These are iron-sulfur proteins that also play a role in electron transfer. They are involved in various metabolic reactions, including those in photosynthesis and respiration.

### Final Answer
The two iron-containing proteins involved in electron transport are:
1. Cytochromes
2. Ferredoxins
