Cellular Respiration Quiz

Assuming ATP is released, which of the following is the correct summary equation for cellular respiration?

• C6H12O6 + 6O2 6CO2 + 6H2O

• 6CO2 + 6H2O 6C6H12O6 + 6O2

• 6C6H12O6 + 6CO2 6O2 + 6H2O

• 6CO2 + C6H12O6 6H2O + 6O2

Glucose from food must be transformed into _________ before it can be used by cells.

• NADPH

• NADP

• ATP

• H2O

During strenuous exercise, your body can still provide you with the energy to keep going but you typically will experience muscle burning. This is most likely because your cells are utilizing:

• photosynthesis

• aerobic respiration

• lactic acid fermentation

• alcoholic fermentation

The process of cellular respiration ______________________

• Occurs only in animals

• Breaks down food molecules to release energy in the form of ATP

• Must occur before plants are able to carry out photosynthesis

• Is performed only by organisms that are incapable of photosynthesis

The chemical process for cellular respiration releases.

• ADP

• energy

• oxygen

• glucose

The byproducts of cellular respiration include

• energy and oxygen

• glucose and oxygen

• carbon dioxide and water

• carbon dioxide and glucose

How does the body of a runner keep up with the demand for energy when cellular oxygen levels are low?

• through energy production in the mitochondria

• through aerobic respiration in the plasma membrane

• through ATP produced directly from sunlight

• through anaerobic respiration in the cytoplasm

Which step of cellular respiration produces the most ATP?

• glycolysis

• Krebs cycle

• electron transport chain

• Calvin cycle

Where does glycolysis takes place in the cell?

• mitochondrial matrix

• inner membrane of the mitochondria

• chloroplast

• cytoplasm

Overall, cellular respiration is an aerobic process. What does this mean?

• Cellular respiration produces oxygen.

• Cellular respiration requires oxygen.

• Cellular respiration can take place without oxygen.

• Cellular respiration receives oxygen through fermentation.
