Timed AP Biology Exam Practice Review

What type of organism is Cryptosporidium parvum?

• Eukaryotic parasite

• Fungus

• Virus

• Bacteria

How does C. parvum generate ATP?

• Oxidative phosphorylation

• Glycolysis

• Fermentation

• Photosynthesis

What role does lactate dehydrogenase play in C. parvum's ATP production?

• Converts glucose to ATP

• Facilitates fermentation after glycolysis

• Transports electrons in the electron transport chain

• Generates a proton gradient

What is the independent variable in the experiment discussed?

• The concentration of the chemical inhibitors

• The type of cell infected by C. parvum

• The presence of lactate dehydrogenase

• The growth rate of C. parvum

How do non-competitive inhibitors like FX 11 and gauzy pole affect C. parvum?

• By blocking glucose absorption

• By inhibiting lactate dehydrogenase

• By activating fermentation

• By destroying the cell membrane

What effect does the variant of lactate dehydrogenase have on FX 11 treatment?

• Increases its effectiveness

• Makes C. parvum resistant to all treatments

• Decreases its effectiveness

• No effect

Why are human cells not affected by treatments targeting C. parvum's ATP production?

• Human cells do not perform glycolysis

• Human cells have functional mitochondria

• Human cells do not absorb glucose

• Human cells use a different form of lactate dehydrogenase

What is the primary function of chloroplasts in plants?

• To produce oxygen

• To convert glucose into ATP

• To fix carbon into organic molecules

• To fix nitrogen

How does the presence of organelles in cells aid in metabolic functions?

• By reducing the need for ATP

• By eliminating waste products

• By allowing for compartmentalization

• By increasing the cell's size

What is the effect of removing the final electron acceptor in the chloroplast?

• Increases carbon fixation rate

• Decreases carbon fixation rate

• Has no effect on carbon fixation rate

• Stops the production of oxygen
