MM and Enzymes

For Honors Bio Test

Term/QuestionDefinition/Answer
Why is carbon a building block? Because it can bond with 4 other molecules
4 types of macro-molecules Lipids, Proteins, Carbohydrates, and Nucleic Acids
examples of a carbohydrate glucose, cellulose, and starch
examples of a lipid fats, waxes, oils, and cutin
examples of a protein enzymes, hormones, antibodies, and callegen
examples of nucleic acid DNA & RNA
monomer of a carbohydrate saccharide
monomer of a lipid phospholipid
monomer of a protein amino acid
monomer of nucleic acid nucleotide
function of a carbohydrate "easy energy"
function of a lipid long term energy
function of a protein "build and bind"
function of nucleic acid produce protein
A phospholipid is made of... glycerol and fatty acids
A nucleotide is made of... phosphate, sugar, and a base
Amino acids strands are made of... amino acid and pepto bonds
Procedure for testing for carbohydrates STARCH- fill test tubes with 5 ml of substrate add 5 drops of iodine record color change SUGAR- fill test tubes with 5 ml of substrate add 10 drops of Benedict place in heated water record color change
Chemical used in testing for carbohydrates Iodine (starch) and Benedict (sugar)
Color of positive reaction (carbohydrates) Iodine- blue-black Benedict- orange-red
Example of that would test positive for carbohydrates Iodine- potato Benedict- honey, lettuce, and juice
Procedure for testing for lipids divide a brown paper bag into 10 sections place a sample of each food item in each section place aside and wait for the water to dry positive=grease stain
how do you know its a positive reaction ?(lipids) grease spot
Example of that would test positive for lipids corn oil and butter
Procedure for testing for proteins Add biuret to the substance being tested and look for a color change
Chemical used in testing for proteins Biuret
Color of positive reaction (proteins) purple
Example of that would test positive for proteins yogurt, gelatin, and butter
What is "lock and key"? It describes how there is only on enzyme per substrate much like how there is only one lock for each key.
What is the active sight? The place where the enzyme and the substrate bind.
What is activation energy? the energy needed to start a reaction
What does it mean to "denature" an enzyme? To warp the active site so that the enzyme can no longer bind with its substrate and a reaction cannot take place
What does pH and temperature do to an enzyme? It denatures it.
What enzyme is used in the liver lab? catalase
what substrate is used in the liver lab? Hydrogen Peroxide (H2O2)
What is the reactant in the liver lab? Hyrdrogen Peroxide (H2O2)
What is the product in the liver lab? Water (H2O) ans Oxygen (H2)
What is the equation for the liver lab? H2O2 ---> H2O + H2 enzyme: catalase
What is the procedure for the liver lab? -pour 2ml of water in tube 1 and 2ml of hydrogen peroxide(H2O2) in the remaing 6 tubes -add the liver/potato/sand -measure the reaction by measuring from the bottom of the tube to the top of the bubbles
Independent variable in liver lab? food items
Dependent variable in liver lab? reaction height
controlled variable in liver lab? amount of Hydrogen Peroxide (H2O2)

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.
