The compounds that are oxidised during respiration are called

Options

A. Reduced substrates
B. Respiratory substrates
C. Oxidisable compounds
D. Respiratory substances

Explanation

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks for the name of the compounds that are oxidized during the process of respiration in plants.

2. **Identifying the Process of Respiration**: In respiration, organic compounds are broken down to release energy. The primary compound involved in this process is glucose (C6H12O6).

3. **Chemical Equation of Respiration**: The general equation for cellular respiration can be represented as:
\[ C6H12O6 + O2 \rightarrow CO2 + H2O + ATP \]
Here, glucose and oxygen are the reactants, and carbon dioxide, water, and ATP (energy) are the products.

4. **Defining Oxidation in Respiration**: During respiration, glucose is oxidized. Oxidation refers to the loss of electrons or the addition of oxygen to a substance. In this case, glucose is oxidized to form carbon dioxide and water.

5. **Identifying the Compounds**: The compounds that undergo oxidation during respiration are primarily glucose and sometimes other organic molecules that serve as energy sources.

6. **Conclusion**: The compounds that are oxidized during respiration are called **Respiratory Substrates**.

**Final Answer**: The compounds that are oxidized during respiration are called **Respiratory Substrates**.
