Transfers energy from exergonic reactions to endergonic reactions
hydrolysis removes phosphate group from ATP20) Sets ranges for controlled condition, generates output commands when required 21) Microtubules, made of motor proteins found in repiratory system, locomotion of unicllular organisms24) Make up nucleic acids
monomer
Three parts;
Nitrogenous base- adenine, guanine, thymine, cytosine
Five carbon sugar- Deoxyribose
Phosphate group- alternate with deoxyribose, form "backbone" of DNA25) Flexible outer surface of cell, Regulates materials entering and exiting the cell, Seperates interal environment, Communication between cells and cells and eternal envrionment31) Inherited genetic material
Segment of DNA is a gene
Determin traits, regulate activities in the body34) Monitors changes in controlled condition, sends input to control center
usually from nerve impulse |
Across:
1) Degrades unneeded damaged or faulty proteins4) 1 Degree
Sequence of amino acids
Covalent peptide bonds7) helps keep things stable on the inside of the body8) Covalent bond between amino acids
Two amino acids yields dipeptide
Three amino acids yields tipeptide
Four or more peptides yields polypeptide
proteins are 50 or longer amino acids10) Contain digestive enzymes, digest materials taken in by enocytosis, digest "old" organelles, provide membrane amterial to seal plasma membrane via exocytosis13) Discovered by Francis Crick, James Watson, Roalind Franklin
X-ray, crytallography, double helix
adenine base pairs with thymine
Guanine base pairs with cytosine
each strand serves as a template for replication, mutations can occur14) 15) 4 Degrees
Two or more polypeptide chains together, functional protein structure, similar bonds to tertiary structure16) Determine cell shape, Movement of organelles chromosomes and specialized cell projections17) Reverses change in controlled condition
1. Stimulus disrupts homeostasis
2. Recpetors dectect change and send input to control center
3. control center input and sends output
4. effector provides physisological response to return cc to normal
regulates stable conditions19) microtubules arranged in circular pattern22) ribosomial RNA- helps with formation23) Disturbances in the homeostatasis occur when one or more body compenents malfunction, usually happens with a disorder or disease26) Resist mechanical stress, stabilize position of organelles, attach cells to each other.27) Protein synthesis, consists of two subunits, some attached to rough ER, Located in mitochondria28) Denaturation- no longer functional sometimes reversible
can occur when envrionment is altered pH, Temperature, chemical changes, Salt COncentration29) 2 Degrees
Twisting or folding of amino acids
Stablized by hydrogen bonds along polypeptide backbone
form a-hrlix and B- pleated sheet30) Protein synthesis, Ribosomes, Enzymes involved in fatty acid synthesis.32) First discovered in nuclei of cells
Contain carbon, hyrdrogen, oxygen, nitrogen and phosphorous
Two types, Deoxyribonucleic acid, Ribonucleic acid33) Folds of inner membrane, Provide large surface area for celluar respiration reaction, matrix plays role in reactions35) Controls homeostasis be regulating internal environment
two types
positive
negative36) Specialized structures in a cell that perform specific functions, each has own set of enzymes for specific biochemical process, little chemical interference between the reactions37) 3 Degrees
3-D shaped of Polypeptide chain
protein folding, folding determines function of protein, disulfide bridges, hydrogen bonds, ionic bonds, hydrophobic interactions38) Houses the DNA39) Packaging and distribution of proteins "post office"
Pacages lipids
Lysosome synthesis
usually close to the nucleus, arises from rough ER40) single-stranded in humans
adenine base pairs with urcail
Guanine base pairs with cytosine
Three different types;
mRNA
tRNA
rRNA41) Composed of actin and myosin, Generate cellular movement, Provide mechanical support42) All cellular contents between plasma membrane and nucleus, Consists of cytosol and organelles43) Recieves output from control center, produces effect to change controlled condition44) Network of protein filaments extending throughout cytosol, Three types: Microfilaments, Intermediate filaments, Microtubules45) Control movement of substances between nucleus and cytoplasm |
