Energy Matter, Organisation Flashcards
Properties of H2O- polarity
-unequal sharing of e
-Partial positive partial negative
Properties of H2O- universal solvent
Ability to dissolve many polar substances
Properties of H2O- density of water as a solid
Water is less dense as a solid, (important to things that live in cold environments)
Properties of H2O- water as a hydrogen bond
Explains the properties of adhesion, cohesion, and surface tension
Properties of H2O- high specific heat
Amount of heat needed to change the temp of water by 1 degree C
Properties of H2O- high heat of vaporization
Requires a lot of heat energy to change liquid to gas
Properties of H2O- high heat of fusion
Requires a lot of heat energy to change solid water to liquid
In general, the presence of atoms of what elements make a molecule polar
Oxygen and nitrogen
What property do atoms of polar molecules have that help make the molecules they are in
Highly electronegative
Love electrons
Is water polar or non polar
Polar 
What is another term for a polar
Hydrophilic
Dissolves in water
What is another term for nonpolar molecule
Hydrophobic
Hates water
What does acidic hydrogens mean?
The donation of hydrogens
Carbohydrates
CHO
Sugar
Main source of energy for cells
Dehydration synthesis
Remove H2O to Jain monomers
Hydrolysis
Add H2O to split monomers
Lipids
CHOP
Fatty acids
Phospholipids
Steroids
Purpose: energy, isolation, protection in cell membrane
Proteins
ENZYMES
the difference between all proteins is the R-group
Held together by peptide bonds
CHON(S)
All have chain of amino acids
Hemoglobin shape effects function
Nucleic Acid
CHONP
DNA
RNA-makes proteins
Structure-double helix
Function-hereditary material
Protein Synthesis:
-> DNA -> RNA -> proten->trait
Nitrogen in nutrient cycles 
- Nitrogen Creates Nucleotides that is in RNA and makes proteins
- In proteins and Nuclic acid
- Nitrogen is in the air and absorbed by plants, then the plants are eaten by animals that decompose it and it gets put back in the earth
Phosphates in nutrient cycles 
-Phosphates are needed for the development of RNA, DNA.
and
Phospholipids
- in Nuckcic acids
-phosphates are in rocks then uplifted, and further weathered, then it gets in the sail and absorbed by plans that are eaten then decomposed back into the earth
Water in the nutrient cycle
- water is important to the hydrolusis and ochydration sunthisis
- H20 is in carbs, Lipids, proteins and necleic acids
- Water is essental for the construction and deconstruction of macromolecules by hydrolysis add water and dehuptration synthisis (tarl away water)
CO2 in nutrient cycles 
-Carbon is the backbone of the structures of macromolecules
- In Carbs, Lipids, proteiens, and NA
- In atmosphere then absorbed bu trees.
IntO
the ground, or
animals eat then decomposes
Hydrolysis
Add water to break apart molecules
