Who Am I?


Whiteboard:Group Member #1A1, B1, C1, D1, E1, F1, G1, H1


Chlorophyll

  • the green pigment in plants that captures light in photosynthesis


DNA

  • has deoxyribosesugar

  • has nucleotides A, T, C, G

  • inherited genetic material that contains instructions for life

  • double-stranded


Protein

  • macromolecule made of amino acids

  • contains C, O, H and N

  • found in muscles

  • used for growth and repair


Ion

  • examples: H+, OH-

  • an atom with a positive or negative charge

  • # of e- does not equal # of protons

  • lost or gained e-


Inorganic Compound

  • compounds that do not contain C and H

  • don’t come from living things

  • examples: NaOH, FeO


Enzyme-Substrate Complex

  • when an enzyme is bound to an appropriate substrate and bonds are being broken and reformed

  • combination of enzyme and substrate


Carbohydrate

  • a macromolecule that has H and O in the same ratio as water, as well as carbon

  • ‘hydrated carbons’

  • examples: sugar, starch, cellulose, chitin


Organic Compound

  • compounds containing C and H

  • come from living things

  • examples: sugar, nucleic acids


Disaccharide

  • Example: lactose

  • two linked sugars

  • formed through a dehydration synthesis reaction


Substrate

  • example: H2O2 in our liver lab

  • molecule(s) that is changed by an enzyme


ATP (Adenosine Triphosphate)

  • found in all organisms

  • stores energy released from cellular respiration

  • important energy transfer compound in organisms


Chemical Bond

  • represented by lines in models

  • the forces that hold atoms to one another in molecules


Chemical Reaction

  • example: photosynthesis changes CO2 and H2O into C6H12O6 and O2

  • a process that changes one set of chemicals into another


Whiteboard:Group Member #2A2, B2, C2, D2, E2, F2, G2, H2


pH Scale

  • ‘power of hydrogen’

  • measure of H+ ions, acidity

  • ranges from 0 - 14


Polysaccharide

  • formed through many dehydration synthesis reactions

  • many linked sugars

  • complex carbohydrates

  • examples: starch, chitin, cellulose


Polypeptide

  • will be folded into a protein

  • long chain of many linked amino acids


Starch

  • used in Inv. 4.4 & 4.5

  • complex carbohydrate used for energy storage in plants

  • type of polysaccharide


Fat

  • type of lipid made up of fatty acids and glycerol

  • used for energy storage, cushioning, insulation


Compound

  • examples: H2O, CO2, H2O2

  • two or more elements bonded together


Cholesterol

  • a type of lipid made by animals

  • found in cell membranes


Nucleic Acid

  • macromolecule that carries genetic material

  • basic unit is nucleotide

  • examples: DNA, RNA


Atom

  • the basic unit of matter

  • composed of protons, neutrons, and electrons


Monosaccharide

  • example: glucose

  • simple carbohydrates

  • a single molecule of sugar

  • can be linked together to form disaccharides


Decomposition

  • breaking down or taking apart

  • example: when H2O2 was broken down in our liver lab


Hydrolysis

  • example: decomposing starch into glucose)

  • the breaking of bonds by adding water


Carbon Cycle

  • how carbon is exchanged through the environment

  • includes photosynthesis & cellular respiration


Electrons

  • have very little mass

  • negatively charged particles around the nucleus of an atom


Whiteboard:Group Member #3A3, B3, C3, D3, E3, F3, G3, H3


Matter

  • a physical substance that has mass and takes up space

  • can be classified as solids, liquids, or gases


Acid

  • example: HCl

  • solution with lots of H+ ions

  • pH from 0 - 7


ADP

  • ATP that has had a phosphate removed to release energy

Released Energy


Synthesis

  • to combine or put together


Neutrons

  • neutral particles found in the nucleus of an atom


Element

  • more than 100 types

  • pure substance made of one type of atom

  • arranged according to properties in the periodic table


Randomness/Disorder

  • the idea that non-livings are always moving to a state of _____________ while living things, on the other hand, invest energy to create organization


Photosynthesis

  • requires chlorophyll to capture light

  • process used by plants to create sugar using light energy


Fatty Acids

  • chain of linked carbons with many H bonds

  • component of lipids, in addition to glycerol


Buffering Capacity

  • the ability to resist a change in pH


Base

  • Example: NaOH

  • solution with los of OH- ions

  • pH 7 - 14


Neutralize/Neutralization

  • combining an acid and a base to form water


Amino Acids

  • basic unit of proteins
