Lab Practical Review: Simulations

The substrate for amylase is

starch and carbohydrate.

The reagent IKI tests for the presence of

starch.

What is an end product of starch digestion?

maltose and glucose.

Hydrolases are enzymes that break down large molecules into smaller subunits through the addition of ____

water

List the substrate and the subunit product of amylase.

substrate= starch. subunit= maltose

Explain where and why salivary amylase would be most active

most active in the mouth because pH 7 is where its peak activity is.

Where in the body does protein digestion begin?

stomach

The substrate for pepsin is

proteins and peptides

A spectrophometer measures

optical density.

At which pH do you think pepsin will have the highest activity?

activity will remain the same, regardless of pH

Pepsin would be most active

in stomach

With more enzyme activity the optical density

increase

The substrate for lipase is

vegetable oil

When fatty acids are liberated by lipase, the pH

decrease

One of the products of the chemical digestion of lipids is

fatty acids

What is the product of lipase hydrolysis?

fatty acid

which pH is ideal for pancreatic lipase digestion?

pH 7

Where in the body does pancreatic lipase hydrolyze triglycerides?

small intestine
