Carbon Compounds – Microbiology Test 2
The key terms Microbiology Test include, Carbon Compounds.
Which of these catabolic ‘styles’ is most efficient at extracting energy from organic carbon compounds?
aerobic respiration – correct
anaerobiosis and fermentation
anaerobic respiration
they are all the same
What is the objective of cellular respiration?
convert energy stored in carbon -carbon bonds into ATP – correct
acquiring oxygen
making water
glycolysis
Two ATPs per glucose are generated in fermentation
True
False – correct
Humans are obligate aerobes. Therefore our cells never do fermentation.
True
False – correct
Which of these is a product of the transition reaction?
all of these – correct
acetyl
CO2
NADH
What is an enzyme’s substrate?
the produt of the reaction
the molecule upon which it acts – correct
the amino acid composition of the enzyme
all of these
What is an enzyme’s active site
the area where it moves atoms up a concentration gradient
its substrate
none of these
the place on the enzyme where it interacts with its substrate – correct
I am measuring the rate at which the product of an enzyme catalyzed reaction accumulates in a solution. When I add an inhibitor, the rate goes down, and adding more substrate does not change the rate. What kind of inhibitor is this?
competitive
non-competitive – correct
temperature sensitive
protein denaturant
You are studying a biosynthetic pathway and you discover that the final product of the pathway is a non-competitive inhibitor of the first enzyme in the pathway. This phenomenon is called
product cycling
protein denaturation
all of these
feed back inhibition – correct
What do we know about the enzymes produced by bacteria living in 95oC water?
they are stable and active at 95o – correct
these will be denatured
these must be constructed of novel amino acids
nothing can live at 95o
What are the energy and carbon sources of a photoheterotroph?
light, inorganic carbon
light, organic carbon – correct
organic carbon
reduced inorganic molecules, inorganic carbon
What is a psychrophile?
organism that lives in high salt environments
organism that lives at low pH
people that love horror movies
organism that lives at low temperatures – correct
