Statement 1: Oxygen breaks down glucose outside the cells of organisms.
Statement 2: Exhaled air has more percentage of CO₂ than inhaled air.

• A. Statement 1: True; Statement 2: False
• B. Statement 1: False; Statement 2: True
• C. Statement 1: False; Statement 2: False
• D. Statement 1: True; Statement 2: True

Answer 1

The correct option is B Statement 1: False; Statement 2: True

• Blood carries glucose and oxygen to the cell.
• Inside the cell, oxygen breaks down the glucose thereby releasing energy through a process known as cellular respiration.
• Along with energy, carbon dioxide and water are given out as byproducts.
• Exhalation is giving out the air, so the exhaled air has almost 100 times more amount of carbon dioxide than inhaled air.
