Question

part ii determine which enzymes are necessary for the digestion of each of the following!

1. soda contains up to 50 grams of sucrose, a disaccharide molecule composed of a glucose molecule bonded to a fructose molecule. it is broken down in the stomach and intestines.

1. ice cream is a suspension of sugar molecules in frozen fat. malted sugar and lactose are the two primary sugars.

1. french fries are made from potatoes, a plant filled with starch (made of many glucose molecules bound together). potato strips are deep fried in oil, making them one of the fattiest of foods.

1. a cheeseburger typically consists of beef (the muscle tissue of an animal), cheese (a dairy product related to milk), and a bun that contains starch and other complex carbohydrates.

Explanation:

1. Sucrase is needed to break down sucrose (a disaccharide of glucose and fructose) in the stomach and intestines.
2. Maltase for malted sugar (maltose) and lactase for lactose.
3. Amylase to break down starch (many glucose molecules) in potatoes.
4. Protease for beef (protein - muscle tissue), lactase for cheese (if lactose is present in cheese - some cheeses have lactose), and amylase for the starch in the bun.

Answer:

1. Sucrase
2. Maltase, Lactase
3. Amylase
4. Protease, Lactase (if applicable), Amylase
