the final electron acceptor), _________ respiration (nonoxygen
electron acceptors), and __________ (organic molecules as final
electron acceptors). - ANSWERS-aerobic; anaerobic; fermentation
The processes of aerobic and anaerobic respiration, as well as
fermentation, all begin with __________ - ANSWERS-glycolysis
Glycolysis occurs in the __________ and overall generates ___ ATP -
ANSWERS-cytoplasm; 2
,The two molecules of __________ produced in glycolysis can be turned
into acids and other products through __________. - ANSWERS-
pyruvate; fermentation
In other microbes, the process of respiration continues when pyruvate
is utilized in a set of reactions called the ____________. - ANSWERS-
Krebs cycle
The Krebs cycle produces a small amount of ATP, but generates the
reduced ______ NADH and FADH2. - ANSWERS-carriers
These molecules then bring the _______ generated by glycolysis and
the Krebs cycle to the ________ embedded in the bacterial cell
_______. - ANSWERS-electrons; electron transport system; membrane
_______ respirers utilize free oxygen as a final electron acceptor in this
process, while______ respirers use oxygen-containing ions, to create a
range of ATP molecules. - ANSWERS-aerobic; anaerobic
Match the catabolic pathway with its ATP yield/molecule of glucose.
36-38 ATP/molecule of glucose
, 2-36 ATP/molecule of glucose
2 ATP/molecule of glucose - ANSWERS-Aerobic respiration; anaerobic
respiration; fermentation
Both aerobic respiration and anaerobic respiration utilize glycolysis,
Krebs cycle, and an electron transport system, but in ________
respiration, O2 is the final electron acceptor at the end of the electron
transport system, whereas in _________, an inorganic molecule other
than O2 is the final electron acceptor. - ANSWERS-aerobic; anaerobic
Select each of the statements that describe the Krebs cycle. -
ANSWERS--Pyruvic acid must be converted to acetyl CoA prior to
entering the cycle.
-There are four steps involving redox reaction
-Electrons removed during oxidation steps are picked up by NAD or FAD
-CO2 is released at two steps
-The "starting material" oxaloacetic acid, is regenerated at the "end" of
the cycle
Select those statements that describe anabolic activities. - ANSWERS--
Synthesis of proteins from amino acids
-Formation of cell wall structures from monomer building blocks
-Assembly of DNA and RNA from nucleotides
