Cellular Respiration

Which end product is of greatest benefit to the organism in which fermentation occurs?

• Alcohol
• Lactic Acid
• Pyruvic Acid
• ATP

Green plants use molecular oxygen for

• the hydrolysis of starch during intracellular digestion
• ATP production during aerobic respiration 
• ATP production during anaerobic respiration
• light absorption during photosynthesis

All of the following process produce ATP EXCEPT

• glycolysis
• Krebs Cycle
• formation of acetyl CoA
• oxidative phosphorylation

After strenuous exercise, a muscle cell would contain increased amounts of all the following except

• ADP
• CO2
• lactic acid
• glucose

In glycolysis, glucose is split to form

• 2 molecules of starch
• 2 molecules of oxaloacetate
• 2 molecules of FADH2
• 2 molecules of pyruvic acid

In addition to ATP, what are the end products of glycolysis?

• CO2 and H2O
• CO2 and ethanol
• NADH and pyruvic acid
• CO2 and NADH

How does NAD+ function in glycolysis?

• It provides energy
• It accepts electrons
• It is an enzyme
• It provides electrons

The anaerobic breakdown of glucose is called:

• fermentation
• respiration
• phosphorylation
• chemiosmosis

The potential ATP yield from each FADH2 produced in the Krebs Cycle is

• 2 ATP
• 3 ATP
• 4 ATP
• 38 ATP

Where does fermentation occur within a cell undergoing anaerobic metabolism of glucose?

• Surface of cell membrane
• Stroma of chloroplast
• Mitochondrial matrix
• Cytosol
