Cellular Respiration Exam

Both plant and animal cells have mitochondria and both require ATP for cellular energy

• True

• False

What do you think might happen if mitochondria were removed from cells?

• Lactic acid fermentation occurs

• Glycolysis

• We would not be able to make cellular energy and our cells would die off.

• Anaerobic respiration occurs without the presence of oxygen. Aerobic respiration requires oxygen to occur

What are the products of cellular respiration

• ATP, CO2, H2O, FADH2, NADH

• ATP, CO2, H2O, Lactic Acid

• H2O, FADH2, NADH, O2

• Glucose, pyruvate, FADH2, NADH

If your cells do not get enough oxygen

• Our cells

  make CO2

• lactic acid fermentation occurs

• ATP is formed in the

  inner membrane of the

  mitochondria

• Krebs cycle

Do our cells use food that we eat as a direct energy source?

• Yes our bodies directly use the energy from

  the sugars we eat

• Not directly. Our bodies use the energy from

  the sugars we eat to create ATP, a usable

  cellular energy source.

How do our cells form carbon dioxide?

• difference of protons across the

  mitochondrial membrane.

• make CO2 during the Krebs cycle as a waste

  product after converting glucose into ATP

• Anaerobic respiration occurs

  without the presence of oxygen.

• CO2 is formed in the

  inner membrane of the

  mitochondria

Where is the electron transport chain located?

• Inner membrane of the

  mitochondria.

• Mitochondrial matrix

• The Rough Endoplasmic Reticulum

• Cytoplasm

What are the reactants of cellular respiration?

• 6 CO2 + 6H2O + 36 ATP

• C6H12O6 + 6O2

• Pyruvate; acetyl coA; ATP

• NADH, FADH2, CO2

The energy a cell needs to build molecules or power cell respiration is supplied by

• Electrons

• Water

• ATP

• Carbon dioxide

The energy released from ATP is used to

• Build new molecules

• Perform life activities

• Power chemical reactions

• All of the above
