BIO chapter 6 hw
What is produced during the citric acid cycle?
ATP, NADH, and FADH2.
The equation, C6H12O6 + 6O2 →6CO2 + 6H2O (ATP + heat), describes what process?
ATP, heat, and carbon dioxide
During oxidative phosphorylation, _____ and FADH₂ are oxidized to power ATP production.
NADH
The oxidation of NADH results in the formation of more ATP molecules compared to the oxidation of FADH2 because
NADH enters the electron transport chain at an earlier point than FADH2.
The equation, C6H12O6 + 6O2 →6CO2 + 6H2O (ATP + heat), describes what process?
cellular respiration
In anabolic reactions that involve the synthesis of a large molecule from smaller precursor molecules, NADH and ATP are __________ when they provide the needed electrons or energy.
consumed
Where does glycolysis takes place?
cytosol
pathway of cellular respiration
1 glycolysis 2 breakdown of pyruvate 3 citric acid cycle 4 oxidative phosphorylation
How many net ATP and NADH molecules are produced from one molecule of glucose during glycolysis?
2 ATP, 2 NADH
The net result of a single round of glycolysis is the formation of
2 NADH and 2 ATP
glycolysis and citric acid cycle
2 atp produced
atp synthase
30-34 atp produced
NADH and FADH₂ donate _________ at different points in the electron transport chain.
electrons
An autotroph captures energy from other sources and does not actually produce energy because
energy cannot be created or destroyed.
In prokaryotic cells, the electron transport system occurs in the mitochondria.
false
In cellular respiration, carbon dioxide is formed from the oxidation of which of the following?
glucose
Which of the following is the correct formula for aerobic cellular respiration?
glucose + 6 O2 → 6 CO2 + 6 H2O + energy intermediates + heat

In glycolysis, glucose is converted to
pyruvate
In the reaction Pyruvate + NADH -> Lactate + NAD, pyruvate is being _________.
