The compunds that are oxidised during the respiration process are known as

Options

A. Food molecules
B. Respiratory substrates
C. Inorganic molecules
D. Organic compounds

Answer

**Step-by-Step Solution:**

1. **Identify the Compounds Involved in Respiration:**
The primary compound that is oxidized during the respiration process is glucose, which has the chemical formula C6H12O6.

2. **Understand the Role of Oxygen:**
Oxygen (O2) is required for the oxidation of glucose. During respiration, glucose reacts with oxygen to produce energy.

3. **Products of Respiration:**
The oxidation of glucose in the presence of oxygen results in the formation of carbon dioxide (CO2) and water (H2O), along with the release of energy in the form of ATP (adenosine triphosphate).

4. **Define Respiratory Substrates:**
The compounds that are oxidized during the respiration process are referred to as respiratory substrates. In this case, glucose is the main respiratory substrate.

5. **Evaluate the Options:**
Given the options:
- Food molecule
- Respiratory substrate
- Inorganic molecule
- Organic molecule

The correct answer is "respiratory substrate," as it specifically refers to the compounds that undergo oxidation during respiration.

6. **Conclude the Answer:**
Therefore, the compounds that are oxidized during the respiration process are known as respiratory substrates.

**Final Answer:**
The compounds that are oxidized during the respiration process are known as **respiratory substrates**.
