Cellular Respiration and Photosynthesis Quiz

What is the primary difference between photosynthesis and cellular respiration?

• Both processes release energy.

• Photosynthesis absorbs energy, while cellular respiration releases it.

• Photosynthesis releases energy, while cellular respiration absorbs it.

• Both processes absorb energy.

Which phase of cellular respiration produces the most ATP?

• Fermentation

• Glycolysis

• Electron transport chain

• Krebs cycle

What is the role of NAD and FAD in cellular respiration?

• They are types of ATP molecules.

• They are electron carriers that transport electrons to the electron transport chain.

• They are enzymes that catalyze reactions.

• They are substrates for glycolysis.

Where does glycolysis occur within the cell?

• In the chloroplast

• In the cytosol

• In the nucleus

• In the mitochondrion

What is the net gain of ATP molecules from glycolysis?

• 8 ATP

• 6 ATP

• 2 ATP

• 4 ATP

What happens to pyruvate during alcoholic fermentation?

• It is converted into ATP.

• It is converted into lactic acid.

• It is converted into alcohol and carbon dioxide.

• It is converted into glucose.

Which organisms typically perform alcoholic fermentation?

• Plants

• Fungi

• Yeast and some bacteria

• Muscle cells

What causes muscle cramps during intense exercise?

• High ATP production

• Alcoholic fermentation

• Lactic acid fermentation

• Excess oxygen in the muscles

Which type of fermentation is used in the production of yogurt?

• Alcoholic fermentation

• Lactic acid fermentation

• Both alcoholic and lactic acid fermentation

• Neither

What is the main purpose of fermentation in cells?

• To produce oxygen

• To regenerate NAD+ for glycolysis

• To convert glucose into pyruvate

• To produce large amounts of ATP
