Question

1. propose a model for how what you identified in question 1 is able to break down cellulose (i.e. what bonds are broken, what type of reaction is taking place).
2. diagram the reaction that would take place to break bonds between two glucose monomers.
3. cattle industries will often add antibiotics in their feed. what is the purpose of antibiotics? why might cattle industries use them? you may use online resources to research this.

Explanation:

Step1: Analyze cellulose breakdown

Cellulose is a polysaccharide. Enzymes like cellulases can break - down cellulose. The glycosidic bonds between glucose monomers in cellulose are broken through a hydrolysis reaction.

Step2: Diagram bond - breaking in glucose monomers

The reaction of breaking bonds between two glucose monomers in maltose (a disaccharide) is a hydrolysis reaction. Maltose ($C_{12}H_{22}O_{11}$) reacts with water ($H_2O$) to form two glucose molecules ($C_6H_{12}O_6$). The chemical equation is $C_{12}H_{22}O_{11}+H_2O
ightarrow 2C_6H_{12}O_6$.

Step3: Explain antibiotic use in cattle

Antibiotics are used to prevent and treat bacterial infections in cattle. Cattle industries use them to reduce the incidence of diseases, improve animal health, and increase productivity.

Answer:

1. Cellulose is broken down by enzymes (such as cellulases) through hydrolysis of glycosidic bonds.
2. The reaction of breaking bonds between two glucose monomers in maltose is $C_{12}H_{22}O_{11}+H_2O

ightarrow 2C_6H_{12}O_6$.

1. Antibiotics in cattle feed are used to prevent and treat bacterial infections, improve animal health, and increase productivity.
