redox reactions are reducing and oxidizing reactions that are paired (REDOX)
molecules that gain electrons are called reduced because they have decrease in the
oxidation state (GER)
molecules that lose electrons are oxidized because they have increased their oxidation state
(LEO)
remember LEO goes GER
LEO goes GER leo= lose electrons oxidized
ger= gain electrons reduced
electron carriers like NADH and FADH2 all carry electrons during electron transport
GER gain electrons reduced- so NAD+, FAD+, and NADP+ are reduced to make NADH,
FADH2, and NADPH. NAD+ reduced to NADH--- NAD+ + H+ + 2e + H ---> NADH
pyruvate is oxidized- loses electrons in cellular respiration
for each glucose molecule that is broken down... two ATP molecules are made directly
during the Krebs cycle
the krebs cycle feeds NADh and FADH2 to the electron transport chain, which can produce up
to 34 ATP molecules
, efficiency of aerobic repsiration 50% efficient
NADH makes 3 ATP
FADH2 makes 2 ATP
fossil fuels remains of organisms that have been transformed by decay, heat, and pressure
into energy-rich organic molecules
examples of fossil fuels coal, oil, natural gas
burning fossil fuels releases co2 and energy
greenhouse effect increasing co2 in the atmosphere may trap heat from the sun causing the
Earth to warm
example of the greenhouse effect the sun's energy passes through the car's windshield
global warming the increase of the Earth's average temperature due to a build-up of
greenhouse gases in the atmosphere
climate change a broader term that refers to long-term changes in climate, including
average temperature and precipitation.
effects of global warming rising sea level
habitat damage and species affected
increased temperature
change in water supply
