Practice Performance Task: Cellulase PRACTICE PFOR K Both humans and cows are able to consume plant matter made up of complex carbolydrates, such as starch or cellulose. However. a cow's digestive system is very different from that of a human. As a result, humans and cows differ in their ability to extract nutrients fiom plant-based food resources For example, unlike humans, cows can thrive on grass, which is lareely made up of cellulose Cows are able to digest grass thanks to a complex community of microbes, inclading bacteria, in their digestive system. These bacteria prodoce cellulase, which starts the process of breaking down cellulose into smaller sobbunits of ghacose. Cows then acquire energy as the microbes in their digestive system utilize the glucose to carry out fermentation. A by-product of fermentation by bacteria is methane gas (CH) 1. A student is working on drawing and labeling a very basic model showing how cellulose is broken down. The students work on the model so far is shown below. Rased on the passage above, revise the student's model so that it is correct and complete. Be sure to clearly identify all your revisions to the model. 2 dentify the subunits (monomers) that make up cellulase and those that make up cellulose. Describe the difference in these two macromolecules' roles in cellular systems.

Question
Practice Performance Task: Cellulase PRACTICE PERFOR K Both humans and cows are able to consume plant matter made up of complex carbolydrates, such as starch or cellulose. However, a cow's digestive system is very different from that of a human. As a result, humans and cows differ in their ability to extract nutrients from plant-based food resources For example, unlike humans, vows can thrive on grass, which is largely made up of cellulose Cows are able to digest grass thanks to a complex community of microbes, inchading bacteria, in their digestive system. These bacteria prodoce cellulase, which starts the process of breaking down cellulose into smaller sobbunits of ghacose. Cows then acquire energy as the microbes in their digestive system utilize the glucose to carry out fermentation. A by-product of fermentation by bacteria is methane gas (CH,) 1. A student is working on drawing and labeling a very basic model showing how cellulose is broken down. The students work on the model so far is shown below. Rased on the passage above, revise the student's model so that it is correct and complete. Be sure to clearly identify all your revisions to the model. 2 Identify the subunits (monomers) that make up cellulase and those that make up cellulose. Describe the difference in these two macromolecules' roles in cellular systems.
