|---|---|---|---|---|---|
| Chemical energy | formed in bonds of chemical substance
🗑
|
||||
| Mechanical Energy | directly involved in moving matter
🗑
|
||||
| Electrical Energy | results from movement of charged particles
🗑
|
||||
| Radiant or electromagnetic energy | exhibits wavelike properties (Ultraviolet, X-rays, visual light)
🗑
|
||||
| Kinetic energy | energy in action; kinetic energy is seen in constant movement of the tiniest particles of matter
🗑
|
||||
| Potential energy | Is stored energy which has the potential to do work but is not presently doing so.
🗑
|
||||
| Protons charge & amu | Protons have a positive charge & 1 amu
🗑
|
||||
| Neutrons | Neutrons have no charge/ neutral charge and 1 amu
🗑
|
||||
| Electrons | electrons have a negative charge and 0 amu
🗑
|
||||
| atomic number | number of protons in the nucleus
🗑
|
||||
| atomic mass | sum of protons and neutrons
🗑
|
||||
| isotopes | structural variations of elements that differ in number of neutrons they contain
🗑
|
||||
| Ionic bond | formed by the transfer of valence shell electrons between atoms
🗑
|
||||
| polar covalent bond | is a bond between two non metals with different electrnegativities
🗑
|
||||
| Non polar covalent bond | the two atoms sharing electrons, share them equally
🗑
|
||||
| Hydrogen bond | they form when an hydrogen atom already covalently linked to one electronegative atom is attracted by another electron-hungry atom, so that a “bridge” forms between them.
🗑
|
||||
| synthesis reaction | when atoms or molecules are combined to form a larger more complex molecule A+B=AB
🗑
|
||||
| Decomposition reaction | occurs when a molecule is broken down into smaller molecules, bonds are broken AB=A+B
🗑
|
||||
| Exchange reaction | involve both synthesis and decomposition; bonds are both broken and made AB+C → AC+B
🗑
|
||||
| Properties of water | 1. high heat capacity-absorbs &releases heat with little temp. change and prevents sudden changes in temp.
2. high heat of vaporization-useful cooling mechanism
3. polar solvent properties
4. Reactivity- necessary in hydrolysis and dehydration synthesi
🗑
|
||||
| Salts | ionic compound that dissociates in wate, contains cation and anions other than H+ and OH-
ions conduct electrical currents in solution
🗑
|
||||
| acids | have sour taste,can react with many metals, an acid is a substance that releases Hydrogen ions (H+) in detectable amounts.
🗑
|
||||
| base | has bitter taste, slippery,and are proton acceptors- that is they take up hydrogen ions in detectable amounts. Bases= OH-
🗑
|
||||
| buffers | a mixture of compounds that resist pH changes they convert strong acids or bases into weak ones
🗑
|
||||
| carbohydrates; building blocks and examples | monosaccarides (simple sugars)
examples: sugars & starches major source of cellular fuel
🗑
|
||||
| Lipids; building blocks & examples | triglycerides
Examples: fatty acids & glycerol
🗑
|
||||
| Proteins; building blocks & examples | amino acids
examples: glycine, alanine
🗑
|
||||
| Nucleic acid; building blocks & examples | Nucleotides
examples: cytosine, adenine, guanine
🗑
|
||||
| Fibrous proteins | structural, strandlike, water insoluble and stable
ex: Elastin & collagen
🗑
|
||||
| globular proteins | functional, spherical, water soluble and sensitive to environmental changes
ex: hormones& antibodies
🗑
|
||||
| Enzymes | biological catalysts, lower the activation energy, increase the speed of reaction
🗑
|
||||
| catalysts | substances that regulate and accelerate reactions
🗑
|
||||
| ATP | Adenosine Triphosphate ; adenine-containing RNA nucleotide with two additional phosphate groups.
🗑
