Production of Energy through Cell Respiration

7.1 Production of Energy Through Cellular Respiration
 
Introduction
  • Metabolic reaction which are anabolism and catabolism involve energy.
    • Catabolism process releases energy.
    • Anabolism process uses energy.
  • Without energy, the anabolic processes such as protein formation which is the basic muscle substance will not occur.
 
The Main Substrate in Energy Production
  • Cellular respiration is carried out to generate the energy needed by all living cells.
  • Cellular respiration is the oxidation process of organic molecules through several stages to release energy.
  • The main substrate for cellular respiration is glucose.
  • Chemical energy found in glucose is released to produce energy required by cells.
  • In humans and animals, glucose is obtained through the digestion of carbohydrates from the food eaten.
  • In green plants, light energy can be trapped by chlorophyll for the photosynthesis process to produce glucose.
 
Types of Cellular Respiration
  • There are two types of cellular respiration, which are aerobic and anaerobic respiration.
  • Fermentation is an alternative pathway of obtaining energy besides cellular respiration.
