Cellular Respiration Production of Oxygen

by Contributing Writer
  • Overview

    The process of cellular respiration uses oxygen to break down sugars (stored energy) and gives off carbon dioxide as a byproduct. On the opposite side, photosynthesis uses carbon dioxide to store energy from the sun as glucose, giving off oxygen as byproduct.
  • Mitochondria

    There are between 1,000 and 2,000 mitochondria per cell in animals (including humans), providing energy for necessary functions by making adenosine triphosphate (ATP) through the process of cellular respiration.
  • Cellular respiration

    Cellular respiration converts energy stored in glucose (sugars) into the ATP needed to power cells by using oxygen to break down the sugars, giving off water and carbon dioxide as byproducts.
  • Photosynthesis

    The process of photosynthesis is cellular respiration in reverse---the conversion of solar energy into glucose through the use of carbon dioxide, giving off oxygen as a byproduct. Photosynthesis occurs in all plants containing chloroplasts.
  • Chlorophyll

    Chlorophyll is a pigment located in chloroplasts that absorbs light from the sun, converting it from solar energy into the chemical energy that is used by mitochondria in both plants and animals to power cell processes.
  • Formulae

    The formula for cellular respiration is written as C6H12O6 +6 O2 +6H2O ' 6CO2+12 H2O + energy. The formula for photosynthesis is written as 6CO2+12 H2O + energy ' C6H12O6 +6 O2 +6H2O. Both processes are vital to life on our planet, and are mirror images of each other.
