Cellular Respiration

Cellular respiration occurs in

• animal cells only

• plant cells only

• all eukaryotic cells

• prokaryotic cells only

What is the correct equation for cellular respiration?

• 6CO2 + 6H2O + Energy = 6CO2 + C6H12O6

• 6O2 + C6H12O6 = 6CO2 + 6H2O + Energy

• 6O2 + C6H12O6 + Energy = 6CO2 + 6H2O

• 6CO2 + 6H2O = 6O2 + C6H12O6 + Energy

Glycolysis requires

• NADP+

• sunlight

• oxygen

• ATP

The Krebs Cycle produces

• carbon dioxide

• lactic acid

• oxygen

• glucose

The Krebs cycle starts with

• lactic acid that yields carbon dioxide

• glucose that yields ATP

• pyruvic acid that yields carbon dioxide

• pyruvic acid that yields lactic acid

Cellular respiration uses one molecule of gucose to produce approximately

• 2 ATP molecules

• 4 ATP molecules

• 30 ATP molecules

• 36 ATP molecules

Cellular respiration is called an aerobic process because it requires

• glucose

• light

• exercise

• oxygen

The starting molecule for glycolysis is

• glucose

• ADP

• pyruvate

• carbon dioxide

If oxygen is present, glycolysis is followed by

• the Krebs cycle

• lactic acid fermentation

• photosynthesis

• alcoholic fermentation

Which process takes place in the cytoplasm of the cell

• electron transport chain

• Krebs cycle

• glycolysis

• photosynthesis
