What compound has the fastest rate of decomposition?Group of answer choicesCelluloseProteinGlucoseLignin

To determine which compound has the fastest rate of decomposition among cellulose, protein, glucose, and lignin, we should consider the structure and properties of these compounds.

1. Cellulose: This is a polysaccharide consisting of long chains of glucose units. It is resistant to degradation due to its strong hydrogen bonding and crystalline structure, which makes it more stable and slower to decompose.

2. Protein: Proteins are made up of amino acids and can decompose relatively quickly due to the presence of various enzyme systems that target peptide bonds. However, the rate of decomposition can vary based on factors such as environmental conditions and the specific type of protein.

3. Glucose: This simple sugar can decompose quickly under certain conditions, especially during fermentation processes by microorganisms. However, it is relatively stable compared to proteins when isolated.

4. Lignin: This complex organic polymer is highly resistant to degradation and is one of the main components of plant cell walls. It decomposes much slower than cellulose and proteins.

Based on these characteristics, proteins generally have the fastest rate of decomposition, particularly under favorable environmental conditions (like the presence of moisture and heat), because they are the most readily attacked by microorganisms and enzymes compared to the other compounds listed.

Final Answer

The compound with the fastest rate of decomposition is Protein.
