Glucose, fructose, galactose... 

What is a monosaccharide?

100

Mass/Volume

What is Density?

100

The property of enzymes to ONLY bind one substrate or group of substrates at the active site. 

What is Enzyme Specificity?

OR What is Lock and Key?

100

Reagent that that detects the presence of monosaccharides and certain disaccharides (short chain carbs). 

What is Benedict's reagent?

100

You have a stone with a volume of 15 cm3 and a mass of 90g. What is its density?

6 g/cm3

200
A central carbon surrounded by 4 groups (Hydrogen, Amino, Carboxyl, and R group)
What is an amino acid?
200
The name of the value indicated by the formula


(Mass of solute/volume of solution)x100 

What is mass percent? 

200
Formed when the substrate binds at the active site of the enzyme. 

What is the enzyme-substrate complex?

200

A solution of walrus blubber turns orange/ reddish in the presence of this lab reagent.

(This reagent is now classified as a Category 3 carcinogen!)

What is Sudan IV?

200

You have a spoon of methane with a density of 0.696, a spoon of seawater with a density of 1.03, a spoon of mercury with a density of 13.55, a spoon of turpentine with a density of 0.85, and a spoon of ethyl alcohol with a density of 0.791. How do these liquids stack up (from BOTTOM TO TOP) when you combine them in a graduated cylinder?

Mercury --> seawater --> Turpentine --> Ethyl Alcohol --> Methane.

300

This macromolecule fulfills VERY important functions: thermoregulation, reserve fuel, storage, hormonal messengers...

What are lipids?

300

Solve for the concentration OR volume of a FINAL solution given the concentration and volume of an ORIGINAL solution. 

What is C1V1=C2V2?

300

The tendency of enzymes to operate at specific pH levels, temperature levels, and ionic environments. 

What is the optimal range?

300

Reagent that turns PURPLE in a sample of meat powder (which contains many peptide bonds).

(Hint: Which category of macromolecules contain peptide bonds?)

What is the Biuret reagent?

300

I want to make a 25% (mass/volume) solution of NaCl that occupies 550 mL. How many grams of salt do I need?

Mass/Volume % = (mass/ volume) x 100


25% = (x grams/ 550 mL) x 100

(.25)(550) = 137.5 grams of NaCl 

400

Long chain of amino acids.

What is a polypeptide?

400

6 x 1023 

What is 1 mole?

Or what is Avogadro's number? (also acceptable)

400

Tendency of enzyme activity to "max out" or "plateau" as substrate concentration increases.

What is saturation?

400

A solution of potato starch turns intense blue-black in the presence of this reagent. 

What is iodine?

400

Salvador has 20 L of a 2 M solution. To this solution he adds 30 L. What is the final concentration of the solution?

C1V1=C2V2

(2M)(20L)=(x)(20L+30L)

40 = 50x

x = .8 M


500
The process of joining two monosaccharides OR 2 amino acids. 

What is dehydration synthesis? 

500

10-6  grams 

What is a microgram?

500

How enzymes speed up chemical reactions.

What is lowering activation energy?
500

A device that uses transmitted light passing through a sample to measure the concentrations of different solutions.

What is a spectrophotometer?

500

We start with a stock solution of HCl that is 6 M. What volume of stock solution do we need to use to create 2.5 L of 2 M HCl?

C1V1 = C2V2

(6 M) (x L) = (2.5 L)(2M)

x = .83 L of stock HCl
