Why is it potentially disastrous when an industrial process raises the temperature of a nearby river or lake?Select the correct answer below:it contributes to climate changeit raises the carbon dioxide concentration in the waterit raises the oxygen concentration in the waterit reduces the oxygen concentration in the water
hydrogen bonding between carbonyl oxygen atoms and nitrogen atoms of amide groups causes a polypeptide coiling or folding
the 3D shape adopted by an entire peptide chain. the peptide generally folds into a shape that maximizes its stability through side chain interactions
When a carbonated beverage is sealed, it is:Select the correct answer below:unsaturated with carbon dioxidesaturated with carbon dioxidesupersaturated with carbon dioxidesaturated with oxygen
A certain liquid sample contains a small amount of dissolved chloroform. Which of the following would be the most effective way to rid the liquid of chloroform?Select the correct answer below:Leaving the sample open to the atmosphere in the laboratoryChilling the sample in a freezer, and providing an outlet for the gas to flow into a storage containerHeating the sample gently, and providing an outlet for the gas to flow into a storage containerCapping the container tightly and shaking it
a protein with two or more peptide chains
Which of the following is likely to happen when a glass of cold water is warmed to room temperature?Select the correct answer below:The water will absorb air as the solubility of its dissolved air increases.Small air bubbles will form as the solubility of its dissolved air decreases.The water will neither absorb nor release air because the solubility of its dissolved air does not change.We need more information to predict what will happen to the water.
peptide bonds join amino acids in a polypeptide chain
compound that contains two functional groups - an amino group (NH2) and a carboxyl group (COOH) bonded to the same carbon
what indirectly increases EPI synthesis?
if tyramine is being used as a false transmitter, what happens when a MAO-I is applied?
in addition to the amino and carboxyl groups, what other functional groups are present in cysteine
what type of bonding is responsible for the primary structure of a protein
the arrangement of localized regions of a protein. these regions arise due to the hydrogen bonding between the N-H proton of one amide and the C=O oxygen of another
side groups of the two different polypeptides interact to form ionic bonds
compound that contains many amino acids joined together by amide bonds
neutral compound that contains both a positive and negative charge
about 90% of DA is taken up by.....into pre- and postsynaptic cells
what are good anti-emetics? (not a drug, more like which type of receptor is targeted for these types of drugs and is it an antagonist or agonist?)
a reinforcement event such as a pay raise, does what to DA? what do natural rewards (food, liquids, sex,etc.) do to DA?
