Distinctive properties of livin systems
highly oganized, serv functional purposes, atiely engaged, remarkable capciy for self-repliction
How does solar energ flow troughout the ecosytem?
solar enrgy= photsyntetic oganizums to herbivores and carnvores. Plants captue the energy through ATP; organizums through NADPH
How do the two sides of DNA join togetr?
H bonding. leads to structural complimentarity
Why are H,C,N and O used in biology?
because the form covalent bonds which are necessary for life on earth, they can electron share.
What is the bond energy for H-H?
436
What is the bond energy for C-H?
414
What is the bond enrgy for C-C?
343
What is thebond energy for C-O?
351
How can C-C bonds be arranged?
Linearly, cyclically, branched, planar
The length of a water molecule is approximately what?
3A or .3nm
inorganic precursors
18-64 daltons, C02, H20,NH4,Nitrogen, Nitrate (NO3-)
Metabolites
(50-250)pyruvrate, citrate, succinate, glyceraldehyde, Fructose 1-6 biphosphate, 3-phosphoric acid
Building blocks
amino acids,nucleotide, monosaccarides, fatty acids, glycerol (100-350)
Macromolecules
Proteins, neucleic acids, polysaccarides, lipids (10^3- 10^6 daltons)
Supramleclar cmplxes
ribosomes, cytoskeleton, multiezyme complexes (10^6-10^9)
Organelles
Nucleus, mitochondria,choloroplasts, ER, Golgi
Polypeptide bonds join what?
Polypeptide bonds join amino acid complexes together.
How are polysaccharides joind together?
by joining the 1 and the 4 carbons together for each perspective one
How r nucleic acid polymers joined together?
5 to 3
What is the main thing that is holding all of the biological molcules together?
weak forces- energies for these weak foces range from .4 to 30kJ, van der Waals, Hydroge bonds, Ionic interactions, Hydrophobic interactons
Van der Waals interactions
.4-4 kj/mol
Hydogn bonds
12-30 kJ/mol
Ionic interactions
20 kJ/mol
Hydrophobic ineractions
< 40 kJ/mol
What r some important points about weak moleclar forces?
biological recognition is mediated by weak chemical forces.
Weak forces restrict organisms to a narrow range of envionmental conditions.
How do you determine van der Waals interactions?
it is a function that is based on distance between the centers of 2 atoms
What are some important proton donors?
Carboxylic acids, alcohols, NH2, secondary nitrogens
What are important proton acceptors?
Carbonyl oxygn,ethers, oxygen of a hydroxyl, tertiary nitrogens, oxygen bounded to a phosphate
Why are ions important to biological conditions?
they give protiens stability
How does one molecule recognize another molecule?
It recognizes it by weak chemical forces via structural complimentarity
How much energy is released when glucose is broken down?
2870 kJ, and it is done in a stepwise fashion, releases heat
What is the difference between prokaryotic and eukaryoti cells?
1 plasma membrane, no nucleus or organelles
much larger, Nucleus and organelles
viruses
genetic elements enclosed in a protien coat, reproduce only wth other cells
Virus life cycle
mobile bits of genetic information enclosed in a protien coat.
