5

What role does cellular respiration play in the water cycle?

A
It releases cap h sub 2 cap o to the atmosphere during electron transport.
B
It removes cap h sub 2 cap o from the atmosphere during acetyl CoA formation.
C
It removes cap h sub 2 cap o from the atmosphere during glycolysis.
D
It releases cap h sub 2 cap o to the atmosphere during the citric acid cycle.
6

What is the main transformation that occurs during glycolysis?

A
Glycolysis produces pyruvate, ATP, and NADH by oxidizing glucose.
B
Glycolysis produces ATP and pyruvate by oxidizing glucose and NAD raised to the plus power .
C
Glycolysis produces CO sub 2 , ATP, and pyruvate by reducing glucose.
D
Glycolysis produces ATP and pyruvate by oxidizing water.
7

During the citric acid cycle, what happens to acetyl-CoA?

A
It enters the citric acid cycle and associates with a 4-carbon molecule, forming citric acid, and then through redox reactions regenerates the 4-carbon molecule.
B
It enters the citric acid cycle and gains carbon dioxide to form citric acid, and gains more carbon dioxide through redox reactions to form a 4-carbon molecule.
C
It enters glycolysis and associates with a 5-carbon molecule through redox reactions, forming another acetyl-CoA molecule.
D
It enters the citric acid cycle and associates with a 4-carbon molecule, forming a 5-carbon compound, and then through oxidation reactions regenerates the 4-carbon molecule.
