100
These are the subunits that make up DNA and RNA.
What are nucleic acids/nucleotides?
100
These chemicals increase the rate of chemical reactions without being altered itself.
What is a catalyst?
100
This test is used to identify starch (polysaccharides).
What is the Iodine Test?
100
This organ absorbs water and contains intestinal bacteria that synthesize vitamins.
What is the large intestine?
100
This organ secretes digestive enzymes that are responsible for the breakdown of the three major components of food.
What is the pancreas?
200
This nutrient is made of amino acids joined by peptide (covalent) bonds.
What is protein?
200
This is the site where the substrate molecules attach to the enzyme.
What is the active site?
200
The Benedict's reagent is used to identify these.
What are monosaccharides and disaccharides?
200
This part of the small intestine is the site of major site of digestion.
What is the duodenum?
200
This enzyme is activated by the HCl in the stomach and is the first stage of protein digestion.
What is pepsinogen/pepsin?
300
These provide the body with lots of energy, but take a long time to digest.
What are lipids (fats)?
300
These factors affect enzyme reactions. (Name 3 of the 5 factors.)
What is pH, temperature, substrate molecule concentration, competitive inhibition, or cofactors and coenzymes?
300
This reagent causes a solution containing protein to turn purple.
What is the Biuret reagent?
300
These are two functions of the gallbladder.
What is the storage of bile salts that neutralize the pH of chyme as it enters the small intestine and aiding in the physical digestion of fats?
300
This enzyme is secreted from the salivary glands and the pancreas to breakdown carbohydrates into monosaccharides.
What is amylase?
400
These are digested easily and are therefore a fast source of energy.
What are carbohydrates?
400

The two locations in which amylase is active and the nutrient it works on

What is starch and the mouth/small intestine?

400
Adding Benedict's reagent to a solution results in the mixture becoming blue. This indicates the _______ of monosaccharides.
What is absence?
400
This organ stores glycogen to regulate blood-glucose levels.
What is the liver?
400
This hormone is released from the duodenum when food enters and is carried by the circulatory system to stimulate the gallbladder and the pancreas.
What is secretin?
500
This word describes some nutrients that must be obtained through food (cannot be made in the body)?
What is essential?
500

This 3 enzymes involved in protein digestion

What are pepsin, trypsin and erepsin?

500
If I perform an Iodine Test on a solution containing starch, I would expect to see this colour change.
What is blue/black?
500
These are the three cell types in the stomach and what they secrete.
What are the mucous cells (secrete mucous), parietal cells (secret HCl), and peptic cells (secrete pepsinogen)?
500
This is the ENTIRE pathway (including all enzymes and significant hormones) involved in the digestion of proteins.
See teacher for pathway.
