Biomolecules
What is the function of nucleic acids?
Code for traits; heredity
Name two kinds of food that have saturated fat? (Bad fat that is solid at room temperature!)
Butter, Lard, Meat fat
What is the difference between organic and inorganic molecules?
Organic--contains carbon Inorganic--does NOT contain carbon
What is the purpose of an enzyme?
To catalyze (speed up) a chemical reaction
What are the building blocks of polymers called?
Monomers
What is the function of lipids in a person's diet?
Long-term energy storage
Describe what lipids can do to damage blood vessels.
Fat builds up along blood vessels and causes blockage, which causes a blot clot. This can lead to heart attack or stroke.
What is the difference between molecules and compounds?
Molecules are compounds of the same element (O6 or S2)
Compounds are any two elements combined - can be O2, S5 or C6H12O6
How does an enzyme affect the energy level required to start a reaction?
Lowers it
Which macromolecules have C, H, O
Only Lipids and Carbohydrates
What is the function of proteins?
Cell repair. That's why girls will use keratin treatment in hair!
What is a 5pH (acid or base)? Does it have more hydrogen ions (H+) or hydroxide ions (OH-)
Acid and more H+ ions
What is an ionic bond?
Transfer of electrons or metal and nonmetal.
Can you reuse enzymes
Yes
What are the monomers of proteins. Bonus for 100: How many are there?
Amino Acids
What kind of carbohydrates function as long-term energy storage?
Polymers/Polysaccharides = starch, vegetables, grains, bread
What is the property of water that bonds water molecules to itself? To other molecules?
Cohesion
Adhesion
Describe the polarity of a water molecule, and its effect on other water molecules.
Hydrogen atoms are slightly positive and Oxygen atoms are slightly negative; this causes hydrogen bonding which makes water cohesive.
What is the name of the place on an enzyme where its molecule binds?
Active site
Name all the monomers of each macromolecule.
Carbs: Monosaccharides
Lipids: Triglycerides
Nucleic Acids: Nucleotides
Proteins: Amino Acids
What are enzymes and what macromolecule are they part of?
Enzymes are proteins that speed up chemical reactions.
Draw an atom of Potassium and tell me how many protons, electrons, and neutrons and where they are located.
TBD
Identify the difference between ionic and covalent bonds
Ionic--give and take of electrons Covalent--sharing electrons
Name 2 factors that effect enzymes
Temperature, pH (acid/base solution),
