What are the four distinctive properties of living systems?
|
-living systems are very complicated and highly organized. -biological structures serve functional purposes. (neck, eyes,] -living systems are actively engaged in energy transformations. energy flow. at a steady state we would be dead at equillibrium. -living systems have the capacity to self resplicated[DNA Replication]
|
 Phospho-ester bonds are used for what? |
To store energy from sugars.
|
|
Name the biological atoms of life?percentage they make up in the human body? Property that unites them together which is important for the chemistry of llife? what do the others do?
|
Hydrogen, carbon, nitrogen, oxygen. They make up 99% of the human body.their ability to form covalent bonds by electron pair sharing. Carbon forms long chains and branched structures of 3D shapes.Give functionality to carbon organic compounds.
|
|
Linear aliphatic, cyclic, branched and planar are all examples of what?
|
3-D structures of biological molecules.
|
|
Example ProblemCH4+202=CO2+2H20
|
-752 KJ/react
|
|
Macromolecules and their building blocks have what?
|
Sense or directionality:Proteins: Amino acids, DNA 5'-3'-informational "DNA HARD DRIVE and RNA RAM
|
|
What are Biomolecules?
|
weak forces that maintain biological structures, determine biomolecular interactions as well as a narrow range for life conditions. Also use the same functional groups and laws as per in vitro chemistry . But, they are highly specific and efficient due to enzymes.
|
|
What are the ACS guidelines?
|
Evolution outcomes are conserved.structure determines function (think about why do we have two and two arms-movement regulation)biochemical information is transferred exchanged and store (DNA)biomolecules are altered through pathways involving transformation of energy and matter)
|
|
What element will form hydrogen bonds? properties of hydrogen bonds?
|
Any electonegative atoms such as flouride (F), nitrogen (N), hydrogen oxide(0H)fast dynamics, directional, not a true bond and strongest of all noncovalent forces
|
|
Define hyrated ions
|
Ions that absorbs water molecules from its environment and includes it as part of it structure.
|
|
There are a series if antibiotics called ionophores. They kill bacteria by "breaking" the concentration gradient across a bacterial cell membrane. Thus the ions and molecules inside the bacteria reach equilibrium with the ions and molecules outside the bacteria. What property of living systems explains why the bacteria are killed?
|
The third because there is no energy coming in and out of the system.
|
|
Energy dissociation math problem: How much energy is released per reaction? C2H6 + O2---->CO2 + H20

Remember that weak IM forces determine biomolecular interactions, such as two proteins with each other. which of the following interactions are likely to take place. (Proteins) NH3+-------OOC (Protein) (Enzyme) OH-------HO(Substrate) (Substrate) Benzene------HO(Enzyme) (Substrate) Benzene--------C4H10(Enzyme)
