Chapter 1 Flashcards
Carbohydrates are for
… Energy
Proteins are for…
…growth repair
Lipids are for…
…fats oils and waxes
Nucleic acids
DNA/genetic info
Chonps stands for
C carbon
H hydrogen
O oxygen
N nitrogen
P phosphorus
S sulfur
The difference between sugar and starch
Sugar is quick and starch takes longer
All living things must…
Genetic code, respond to stimulus, cells, reproduce, homeostasis, evolve, and obtain material and energy
Respiration
c6H12o6+6o2 arrow 6h2o+ 6C02+ energy
Glucose + oxygen arrow water + carbon dioxide + energy
Photosynthesis
Water + carbon dioxide + energy equals glucose + oxygen
Atoms are made from
Elements
Why is water polar
Positive negative ends and vice versa. This creates bubbles. Easy to break.
Properties due to polar
Dissolves many things
Enzymes
Natures catalyst and proteins. Without catalyst, you die
Activation energy
Energy needed to start a chemical reaction. Catalyst speed up chemical reactions by lowering the activation energy
Why is carbon important
Carbon is organic. Carbon makes four bonds. Carbon likes to bond with itself. Many things are carbon base
Buffers
When your body becomes too acidic or basic they are released and counter it
Bias
Example. Political parties and who they vote for
Specific heat
Make sure your body doesn’t Vary
Science
To know. You have to be able to prove
Parts and Locations of an Atom
Neutrons and protons are in the middle. Electrons are on the outside.
(Blank) electrons form bonds
Valence
Type of bonds
Covalent – shares
Ionic – give-and-take
Hydrogen – opposites attract
Polarity
Example: water molecules. Attract each other. Positive and negative’s. Makes water cohesive, solvent, and expands when cold.
Theory
Many hypothesis added together
Hypothesis
An educated guess, one thing
Four macromolecules
Carbohydrates, proteins, lipids, and Nucleic acids
Sugar=?
Starch=?
Sugar-quick
Starch- longer lasting
Protein
Catalyst on the fight germs, help stuff in and out of cells, growth and repair
Compound
Two or more elements chemically combined
Adhesion
Climbs
Water molecules are…
Polar
The differences between acids and bases
Acids have more hydrogen ions. (H+)
Bases have more Oh ions (Oh-)
