ANCE 3. Humans produce the enzyme amylase. This enzyme breaks down starch, a complex carbohydrate found in many food sources (e.g.. potatoes, breads). Explain why the human digestive system is unable to use amylase to break down the complex carbohydrate cellulose, which is also found in some foods (such as celery).

Hello! Please help me with this thank u
ANCE 3. Humans produce the enzyme amylase. This enzyme breaks down starch, a complex carbohydrate found in many food sources (e.g.. potatoes, breads). Explain why the human digestive system is unable to use amylase to break down the complex carbohydrate cellulose, which is also found in some foods (such as celery). 4. A team of scientists conducted a study to examine how different temperatures affect the reaction rate of cellulase. To determine reaction rate, they measured the amount of methane released by cellulase-producing bacteria in the presence of cellulose. The following graph shows the data the scientists collected during their study. Gas produced (mL) 2 20 30 40 50 60 70 80 90 100 Temperature (°C)

(a) Use the graph to identify the temperature at which the cellulase reaction rate is the highest. (b) The scientists are interested in examining other factors that could affect the reaction rate of cellulase. Think about an idea for their next experiment: what factor could they test to determine its effect on cellulase's reaction rate? Then, in the table below, identify the variables they should use in that experiment. Independent Variable Dependent Variable Controlled Variables PRACTICE PERFORMANCE TASK
