aerobic respiration chapter 8.1-8.2oxidation - answer glucose (C6H12O6) to carbon dioxide (CO2)
reduction - answer oxygen (O2) to water (H2O)
redox reaction - answer the transfer of hydrogen atoms is equivalent to the transfer of
electrons, this process is a ... in which glucose becomes oxidized (lost hydrogen) and
oxygen becomes reduced (gains hydrogen)
oxygen - answer aerobic respiration includes a series of redox reactions in which
electrons associated with the hydrogen atoms in glucose are transferred to ... in a series
of steps.
the four stages - answer1) glycolysis,
2) formation of acetyl coenzyme A
3) citric acid cycle
4) electron transport and chemiosmosis
prokaryotes - answer carry aerobic respiration in the cytosol and in association with the
plasma membrane because they don't have a mitochondria.
glycolysis - answercytoplasms,
Series of reactions in which glucose is degraded to pyruvate; net profit of 2 ATPs;
electrons are transferred to carriers; can proceed anaerobically
substrate level phosphorylation helps with this.
Start: Glucose, ATP, NAD+, ADP, Pi
End: Pyruvate, 4 ATP, 2 NADH
net yield is 2 ATP and 2 water sometimes
acetyl coA - answeraerobic/ mitochondria matrix
in mitochondria
Pyruvate is degraded and combined with coenzyme A to form acetyl CoA; electrons are
transferred to carriers; CO2 is released.
1 NADH is produced per pyruvate
Start: 2 Pyruvate, 2 coenzyme A, 2 NAD+
End: 2 Acetyl CoA, 2 CO2, 2 NADH
citric acid/krebs cycle - answeraerobic/matrix
in mitochondria
Series of reactions in which the acetyl portion of acetyl CoA is degraded to CO2;
electrons are transferred to carriers; ATP is synthesized
