7.1 Production of Energy through Cellular Respiration

What is the main purpose of cellular respiration?

• To produce oxygen
  

• To break down proteins

• To produce energy (ATP)
  

• To produce energy (ATP)
  

Which of the following best describes catabolism?

• Making proteins from amino acids

• Using energy to build large molecules
  

• Storing glucose as glycogen

• 
  Breaking down large molecules to release energy

In aerobic respiration, which gas is required for the process to take place?

• Oxygen

• Carbon dioxide

• Nitrogen

• Hydrogen

The main substrate for cellular respiration

• Amino acid

• Glucose

• Fats

• Carbon dioxide

In humans, glucose is obtained through

• Breathing in oxygen

• Drinking water

• Eating carbohydrate-rich food

• Absorbing sunlight

What is fermentation?

• The process of storing energy in fat cells

• The breakdown of glucose using oxygen to produce energy

• The production of glucose from carbon dioxide

• The incomplete breakdown of glucose without oxygen or limited oxygen to produce energy
