1

In the pancreas, lipase converts fat to:

64% Answer Correctly

simple sugars

complex carbohydrates

amino acids

glycerol and fatty acids


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

Plant cells are surrounded by:

64% Answer Correctly

neither a cell membrane nor a cell wall

a cell membrane and a cell wall

only a cell wall

only a cell membrane


Solution

Animal cells are surrounded by a semipermeable membrane which allows for the transfer of water and oxygen to and from the cell. In plant cells, the cell membrane is surrounded by a somewhat rigid cell wall which provides the cell structure and support.


3

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

63% Answer Correctly

pancreatic amylase

lipase

gastric acid

trypsin


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.


4

Which of the following substances gives up negatively charged hydroxide ions (OH-) when dissolved in water?

42% Answer Correctly

base

acid

hydrogen

ion


Solution

An acid is a substance that gives up positively charged hydrogen ions (H+) when dissolved in water. A base (alkaline) gives up negatively charged hydroxide ions (OH-) when dissolved in water. pH is a scale that measures of how basic or acidic a solution is. Numbered from 0 to 14, solutions with a pH of 7 are neutral, less than 7 are acidic, more than 7 are alkaline.

Convert 0C° to F°.

72% Answer Correctly

16

0

-32

32


Solution

To convert from C° to F° use:

\(F° = {9 \over 5}C° + 32\)

\(F° = {9 \over 5}(0) + 32\)

\(F° = 0 + 32 = 32\)
