3.4 Cellular Respiration

What is the purpose of cellular respiration?

• To create glucose (sugar)

• To create ATP energy from sugar

Do all organisms (including us, plants, animals, etc.) do cellular respiration?

• True

• False

What are the reactants (ingredients) of cellular respiration? Select all that apply.

• Oxygen

• Carbon dioxide

• ATP

• Glucose

• Water

What are the products (results) of cellular respiration? Select all that apply.

• Oxygen

• Carbon dioxide

• ATP

• Glucose

• Water

In which organelle does cellular respiration happen?

During glycolysis at the beginning of cellular respiration, what is being broken down (split) into two parts?

What happens at the Krebs Cycle / Citric Acid Cycle as pyruvate molecules are slowly broken down?

• ATP is released

• Glucose is consumed

• Oxygen is released

• High energy electrons are released

In this diagram, what are the high energy electrons doing?

• Building up the concentration of hydrogen on one side of the membrane

• Chilling.

• Making the ATP synthase spin

• Creating ATP

What forces the ATP Synthase to rotate (spin)?

• The movement of high energy electrons from high to low concentration

• The movement of hydrogen from high to low concentration

• The movement of water from high to low concentration

Once the ATP Synthase rotates/spins, what comes out of the other end? In other words, what does this special "machine" create?
