BIO TEST 1

TEST

QuestionAnswer
Metabolism All of the chemical process of life
Responsiveness Living systems detect and respond to changes in their environments
Movement Cells, organs, and/or bodies move
Growth cells, organs, and bodies all grow
Differenation the proces of celluar specialization
Reproduction both cells and organisms make copies of themselves
Basic Processes of lving systems Metabolism, Reproductive, Differenation, Growth, Movement, Responsiveness
Homestasis A fundemaental patteren found in all living systems
Homestasis is the maintaince of relatively constant conditions inside the body
Starch is majior polyacharide in our diet and the main storage form of gluocse in plants
Glycogen is an imprtnat storage form of glucose in our bodies
Polysaccharides Starch, Glcogen, Celluosle
Polysaccharides result from additioial dehydration synthesis reactions
Lipids contian mostly carbon and hydroyen atoms
Hydropihic Afraid of water
Lipids Fatty acids, Steroids, Phosphollips, Triglycerdies(fats and oils)
Fatty Acids The simplest lipids
C=C DOUBLE BOND
Saturated means it had more hydorgen in it
triglycerdis highly concentrated form of stored chemcial energy
4 levels of protein structure Primary, Secondary, Teritary, Quaternary
Quaatermary occurs when 2 or more polyperptides interact with one another
Secondary involoves local twisting or folding of the polypetides backbone
Teritary reers to the overall 3-dimensinal shape of protein
Primary the sequence of amino acids
Eneymes are protein catalyts that speed up chemical reactions
Electrolytes seperates dissvoloved ions
Polar Covalent when one atom attracts the shared electrons much more strongley than the other
non-polar covalent if two atoms attract the electrons equally
hydrogen bonds both poloar bonds and non-polar bonds molecules have a small seperationof electrical charge
Covalent Bonds two atom often share electrons to fill their valence shells
Ionic Bonds the oppiosite charges of cations and anions allow them to be strongley bound to one another in an ionic bond
ions are atoms that have gained or lost an electron
anions when atoms gain an electron, they are left with a negative charge
cations when atoms lose an electron, they gain a postive charge
Bases release one or more hydrozide ions(OH-)
Acids release one or more hydrogen ions (H+)
Salts dissociate into cations and anions
Saturated means has more hydrogen
Sign any objective evidence of diesase that can be observed or measured
Sign fever, swelling
Cells the basic structure and functional unit of all organisms
Cells smallest stucture
Sympton a subjective change in body function not appereant to an observer
Sympton pain, neausa
Tissue a group of similiar cells and their intercelluar substance joined together to perform a specific function
Organ a structure composed of two or more diferent kinds of tissues with a specfic function and usually a recongizable shape
Organism A total living form
Organism one indivdual
System consits of related organs that have a common function
Physiology science that deals with the functions of an organism or its parts
Anatomy the sructure or study of the stcuture of the body and the realtion of its parts to each other
Water is a solvent
Buffers convert strong acids and bases into weak acids and bases, by adding or removing protons
AMINO ACIDS The Building Blocks of Proteins
Peptide bonds now links the amino acids
Exergonic Reactions out
Exergonic reactions relaese more energy then they absorb
Solute has been dissolved
Solvent is a liquid or gas in which some other substance called solute has been dissolved
Slats when dissolved in water, dissociates into cations and anions
Energonic Reaction within
Energonic Reactions absorb more energy then they release
Monomers one
Polymers more then one
dimer two
Atomic Number the number of prtons
Atomic mass number of prtons + number of neutrons
istopes atoms that vary only in the number or neutrons
molecules are created when two or more atoms share electrons
compound a molecule that contains two or more different elements
Humerus is a long bone in the arm or forlimb that runs from the shoulder to the elbow
Radius usually refers to the distance from its center or axis of symmetry to a point in the periphery
serous fluid is used for various boidly fluids that are typically pale yellow and transparent
Valence outer most cell
organic compounds always contin carbon and hydrogen
Homestasis is the maintaince of realtively constant cionditions inside the body
postive feedback child birth
negative feedback dont like the song turn it down or off
intracelluar fuild the fuild between cells in tissues
plasma the fluid component of blood
lymph the fliud in our lymphatic vessels
cerbrospinal fluid the fluid within the CNS
syonival fluid the fluid within most joints
extrealluar fluid all body fluids other then the ones inide our cells
unsaturated has less hydrogen
