Unit 3 Chapter 12 Cellular Respiration

What happens in cellular respiration?

• Glucose is converted into oxygen

• Glucose is converted into energy

• Oxygen is converted to glucose

• Glucose is formed

When does the anaerobic respiration phase occur?

• In the presence of oxygen

• In the absence of oxygen

• During photosynthesis

• During protein synthesis

What is the byproduct of fermentation in bacteria?

• Oxygen

• Lactic acid

• Carbon dioxide

• Ethanol

What is the most important product of the Krebs cycle?

• High-energy electrons from pyruvate in molecules called electron carriers

• Fermentation to create ATP

• The movement of anything from an area of high concentration to an area of low concentration

• Water

Where is the electron transport chain located in the mitochondria?

• Cytoplasm

• Inner membrane

• Outer membrane

• Matrix

What do the proteins in the electron transport chain do as electrons pass through them?

• Pump hydrogen ions from the matrix to the outermembrane space

• Pump hydrogen ions from the matrix to the intermembrane space

• Produce hydrogen ions

• Pump oxygen ions from the matrix to the intermembrane space

What is the function of ATP synthase?

• Break down ATP

• Synthesize glucose

• Produce ATP

• Transport electrons

What is chemiosmosis in the electron transport chain?

• Movement of electrons

• The movement of hydrogen ions across the inner membrane from high to low concentration

• The movement of hydrogen ions across the inner membrane from low to high concentration

• Breakdown of water

How can exercise result in the production of lactic acid?

• By increasing oxygen supply

• By decreasing glucose levels

• By causing anaerobic respiration

• By enhancing protein synthesis

The electron transport chain, chemiosmosis, and the creation of water are together called ___
