Cellular Respiration Review

The three main pathways of respiration are

• photosynthesis, respiration, cell cycle

• aerobic, glycolysis, anaerobic

• glycolysis, krebs cycle, electron transport chain

• pyruvate oxidation, glycolysis, electron transport chain

Which biomolecule controls every step of the entire respiration pathway?

• carbohydrates

• ATP

• enzymes

• proteins

What process breaks down sugars and makes large amounts of ATP when oxygen is present?

• Anaerobic Respiration
• Cellular Respiration
• Glycolysis
• Photosynthesis

What are the main products of the Krebs Cycle?

• H₂O and CO₂
• NADH, FADH2 and CO₂

• ATP and O₂
• ADP and H₂O

Where does the Electron Transport Chain 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
