What is one difference between cellulose and glucose
A. Cellulose is formed by a chemical reaction while glucose is formed by physical reaction. Cellulose is formed by a chemical reaction while glucose is formed by a physical reaction.
B. Glucose is a carbohydrate while cellulose is a protein.
C. Cellulose is made of glucose molecules while glucose is made of cellulose molecules.
D. Glucose is not used to give structure to plants' cell walls while cellulose is.
D. Glucose is not used to give structure to plants' cell walls while cellulose is.
D. Glucose is not used to give structure to plants' cell walls while cellulose is.
The correct answer is D. Glucose is not used to give structure to plants' cell walls while cellulose is.
To explain how to arrive at this answer, we need to understand the differences between cellulose and glucose. Both cellulose and glucose are carbohydrates, but they have different structures and functions.
Cellulose is a complex carbohydrate that serves as a structural component in plants. It is made up of long chains of glucose molecules bonded together. These chains of glucose form a rigid and tough structure, providing strength and support to plant cell walls.
On the other hand, glucose is a simple sugar and one of the primary sources of energy for living organisms. It is usually present as a monosaccharide, a single sugar molecule. Glucose is utilized in cellular respiration to produce ATP (adenosine triphosphate), which is the energy currency of the cell.
The key difference mentioned in the question is that glucose is not used to give structure to plants' cell walls, while cellulose serves this purpose. Cellulose forms a mesh-like structure that maintains the shape and stability of plant cells, making them rigid. Glucose, being a simple sugar, does not possess this structural role.
Therefore, option D is the correct answer.
