Which of the following polysaccharides is used as structural material for plants

Question

Which of the following polysaccharides is used as structural material for plants? Amylose Cellulose Chitin Glycogen Which of the following statements is true about an enzyme-catalyzed reaction? An enzyme changes the standard free energy (delta G) of the reaction so that it can proceed spontaneously. An enzyme increases the energy of the transition state through complementary intermolecular forces. An enzyme changes the activation energy (delta G^++), which also changes the ratio of products to reactants at equilibrium. An enzyme changes the activation energy (delta G^++), and increases the rate at which equilibrium is reached.

Explanation / Answer

6. cellulose.

cellulose is polysacharides used to structural material for plants.

7. d. An enzyme change the activation energy and increases the rate at which equilibrium is reached.

Enzyme act as catalyst. Enzyme decreases the activation energy more no of molecule reach the activation energy.So increases the rate of reaction.
