Cellular Respiration Review

The cell organelle where cellular respiration occurs is the -

• nucleus

• mitochondria

• cell membrane

• ribosomes

The output/products of cellular respiration are -

• glucose, hemoglobin, and water

• glucose, energy and carbon dioxide

• unicorn farts

• carbon dioxide, energy and water

What are the inputs, or reactants, that cells use in cellular respiration?

• carbon dioxide and water

• starch and protein

• amino acids and glucose

• glucose and oxygen

In what step of cellular respiration is glucose broken down?

• Aerobic Respiration
• Krebs Cycle
• Electron Transport Chain
• Glycolysis

What are the two main products of the Krebs Cycle?

• H₂O and CO₂
• ATP and CO₂
• ATP and O₂
• ADP and H₂O

Where does the ETC get the energy it needs?

• ATP Synthase
• Glycolysis
• Krebs Cycle
• Mitochondria

What do you get at the end of glycolysis?

• Pyruvate, NADH, and ATP
• NAD, Oxygen, and ATP
• Carbon Dioxide, Water, ATP
• NAD, ATP, Pyruvate

Why do you need the Krebs cycle?

• Form Citric Acid that makes NADH, water and CO₂
• Breaking down pyruvate to form NADH and Oxygen
• Producing molecules that carry high energy electrons to the ETC
• bonding coenzyme A to pyruvate

In the ETC, what do we use the energy from the Krebs Cycle for?

• Pump hydrogens across the inner mitochondrial membrane
• Pump ATP from one side of the membrane to the other
• Pump hydrogens with the concentration gradient
• Pump NADH to make ATP

What is the function of oxygen in the process of cellular respiration?

• to deliver hydrogen ions to the electron transport chain
• to pick up electrons at the end of the electron transport chain
• to provide oxygen for the production of carbon dioxide
• to give a source of energy to the Krebs cycle
