Anatomy Chapter 2 Flashcards
Anything that takes up space and has mass
Matter
The study of composition of matter
Chemistry
Basic building block of matter
Atoms
Has a mass positive charge and located in the nucleus
Protons
Has a mass neutral charge located in the nucleus
Neutron
Has no mass negative charge and in the electron cloud
Electrons
Center out cell all mass is here
Nucleus
Surround the nucleus
Electron cloud
Groups of similar atoms
Elements
Abbreviation of elements name
Chemical symbol
What is the weight in order from highest to lowest of human body chemicals
Oxygen Carbon Hydrogen Nitrogen Calcium Phosphorous
Same element with a different number of neurons
Isotopes
Number of protons and neutrons
Mass number
Smallest part of a compound that still acts like that compound
Molecules
Bond formed by transferring electrons
Ionic
Bond that shares electrons
Covalent
Define shape and definite volume
Solid
Definite volume no define shape
Liquids
No definite shape and boo definite volume
Gasses
Gives of heat makes bonds takes in energy
Exothermic
Gives of heart and breaks bonds
Endothermic
Decomposition
Catabolism
Combines things and forms
Anabolism
Can’t create our destroy matter
Law of conservation of mass
The ability to do work
Energy
Energy in motion
Kinetic
Stored energy
Potential
Can’t create our destroy energy only changes form
Law of conservation of energy
Amount of energy needed to start a chemical reaction
Activation energy
Proteins that are natural catalysts that end in ase
Enzymes
Speeds up chemical reactions
Catalysts
Slows down chemical reactions
Inhibitors
No carbon to hydrogen bonds
Ex. CO2 O2
Inorganic compounds
Strong acid and a strong base equals
Salt
Substances that lower the acidity but raises the pH
Buffers
Have carbon to hydrogen bonds
Organic compounds
Nothing will dissolve
Ex. Fats and oils
Hydrophobic
Dissolve very easy
Ex’s sugars and salts
Hydrophilic
Main energy sugars and starches one to three percent of body mass
Carbohydrates
Suited energy used for protection two tones the energy as carbohydrates
Lipids
Build body tissues twenty percent of body weight
Proteins
DNA and RNA
nucleic acids
Simple sugars glucose and fructose
Monosaccharides
Two monosaccharides put together
Table sugar and lactose
Disaccharides
Starches
Polysaccharides
Used for energy
Fatty acids
Single bond
Ex Butter
Saturated
Double bonded fats
Ex. Olive oil
Unsaturated fats
Chemical messengers
Eicosanoids
Body fat that is stored energy
Insulation protection and cushion
Glycerides
Cholesterol
Used in membranes sexual function tissue metabolism and bile salts
Steroids
Also used in cell membranes
Phospholipids
What are the seven major functions off proteins
Support Movement Transport Buffering Metabolic regulation Coordination and control Defense
Reactant in a reaction
Substrates
Only certain enzymes will break down certain things
Specificity
Only so much enzymes in your body
Saturation limits
The enzyme can be turned on or off
Regulation
Large proteins that act as enzymes antibodies hormones or form cell parts creates mucous
Glycoproteins
Synovial fluid that’s between your joints
Proteoglycans
Generic blueprint that is double stranded
DNA
Controls protein production
RNA
DNA~ ribosome
Messenger(mRNA)
carries amino acids to the ribosome
Transfer(tRNA)
Puts together proteins
Ribosomal (rRNA)
Least energy
AMP
most energy
ATP
