Looking at the biosphere as a whole...the
energy used by your cells to do work ULTIMATELY comes from
When our cells carry out anaerobic respiration they use which one of the following processes?
Lactic acid fermentation
The mitochondrial cristae are an
increases the space for more copies of the electron transport chain and ATP syntheses complexes.
A culture of bacteria growing aerobically is fed glucose containing radioactive carbon and is then examined. As the bacteria metabolize the glucose, radioactivity will appear first in
The functioning of an electron transport
chain is analogous to
a Slinky toy going down a flight of stairs
Which of the following statements is/are true about the energy yields from cellular respiration?
Cellular respiration is more efficient at harnessing energy from glucose than car
engines are at harnessing energy from gasoline.
Both photosynthesis and aerobic cellular
produce ATP by using electron transport chains
The overall equation for the cellular
respiration of glucose is
C6H12O6 + 6 O2 → 6 CO2 + 6H2O + energy.
During which of the following phases of
cellular respiration does substrate-level phosphorylation take place?
glycolysis and the citric acid cycle
Which one of the following is the correct
sequence of stages in cellular respiration?
glycolysis, the citric acid cycle, and oxidative phosphorylation
At the end of the citric acid cycle, most of the energy remaining from the original glucose is stored in
Some friends are trying to make wine in their basement. They've added yeast to a sweet grape juice mixture and have allowed the yeast to grow. After several days they find that sugar levels in the grape juice have dropped, but there's no alcohol in the mixture. The most likely explanation is that:
he mixture needs less oxygen. Yeast only produce alcohol in the absence of oxygen.
ATP is synthesized when H+ ions move through a channel provided by ATP synthase.
