Which of these digestive enzymes is not produced by the pancreas?

63% Answer Correctly

pancreatic amylase

trypsin

lipase

gastric acid


Solution

The acids produced by the pancreas contain several enzymes that aid in digestion.  Lipase converts fat to glycerol and fatty acids. Pancreatic amylase breaks down complex carbohydrates into simple sugars. Trypsin converts polypeptides (the building blocks of protein) into amino acids.


2

Which of the following represents the largest value?

61% Answer Correctly

1 mL

1 ML

1 cL

1 kL


Solution

Mega (M) is 106, kilo (k) is 103, centi (c) is 10-2, milli (m) is 10-3 so 1 ML represents the largest value.


3

Which of these parts of digestion takes place in the mouth?

64% Answer Correctly

breaking down fats

absorbing nutrients

breaking down starches

breaking down proteins


Solution

Digestion begins in the mouth where the teeth and tongue break down food mechanically through chewing and saliva, via the enzyme salivary amylase, starts to break starches down chemically. From the mouth, food travels down the esophagus where contractions push the food into the stomach.


4

Water coming to a boil on a stove, ice melting, and steam from a cup of coffee are all examples of which of the following? 

66% Answer Correctly

radiation

convection

reflection

conduction


Solution

Convection is the transfer of heat by the circulation or movement of the heated parts of a liquid or gas.


5

Molecules and atoms that are outputs from a chemical reaction are known as which of the following?

56% Answer Correctly

side effects

reactants

products

results


Solution

During a chemical reaction molecules and atoms (reactants) are rearranged into new combinations that result in new kinds of atoms or molecules (products).
