UNIT 5 : CELLULAR RESPIRATION

What is cellular respiration?

• Cellular respiration occurs only in the presence of sunlight.
• Cellular respiration is the breakdown of proteins into amino acids.
• Cellular respiration is the process of photosynthesis in plants.
• Cellular respiration is the process by which cells convert glucose and oxygen into energy, carbon dioxide, and water.

What are the products of cellular respiration?

• Carbon dioxide, water, and energy

• Oxygen and glucose
• Nitrogen and ammonia
• Lactic acid and ethanol

What are the reactants of cellular respiration?

• Proteins and fats
• Nutrients and minerals
• Carbon dioxide and water
• Glucose and oxygen

Which process does not directly require oxygen?

• Cellular respiration

• Glycolysis

• Fermentation

• Photosynthesis

What is the main purpose of cellular respiration?

• To produce oxygen

• To break down glucose and produce ATP

• To produce carbon dioxide

• To absorb nutrients

What is the primary function of the ATP molecule in cellular activities?

• To store genetic information

• To serve as the primary energy currency of the cell

• To act as a structural component of cell membranes

• To facilitate passive transport

What is the chemical equation for cellular respiration?

• C6H12O6 + 3 O2 -> 3 CO2 + 3 H2O + energy
• 6 CO2 + 6 H2O -> C6H12O6 + 6 O2 + energy
• C6H12O6 + 6 H2O -> 6 CO2 + 6 O2 + energy
• C6H12O6 + 6 O2 -> 6 CO2 + 6 H2O + energy

What is the chemical formula in word form for cellular respiration?

• carbon plus hydrogen yields glucose plus oxygen
• water plus energy yields glucose plus carbon dioxide
• oxygen plus nitrogen yields glucose plus energy
• glucose plus oxygen yields carbon dioxide plus water plus energy

What is aerobic respiration?

• Anaerobic respiration occurs without oxygen.
• Aerobic respiration is the breakdown of glucose in the absence of oxygen.
• Aerobic respiration is a process that only occurs in plants.
• Aerobic respiration is the process of producing cellular energy in the presence of oxygen.

What is anaerobic respiration?

• Anaerobic respiration is the same as aerobic respiration.
• Anaerobic respiration requires oxygen to produce energy.
• Anaerobic respiration occurs only in plants.
• Anaerobic respiration is the process of producing energy without oxygen.
