Carrying Oxygen and Nutrients to Cell Muscles

• Haemoglobin, otherwise known as red blood cells, carry oxygen from the lungs and heart to the muscle cells in the body. Within the innermost region of the cell is mitochondria, it is often referred to as the powerhouse of the cell. This is where nutrients are converted to energy.
  
  

Converting the Nutrients to Energy

  Cells convert fat, sugar and protein into ATP, or triphosphate, through a process known as glycolysis. The waste products are then released, and the glucose formed from glycolysis is turned into a 6-carbon substance known as pyruvate.
  
  

Energy Stored and Released

• Energy is stored and released and carbon dioxide is released as pyruvate enters into the Krebs cycle and gets rearranged from one molecule to the next. The main goal of this process is to release energy while replenishing the supply of ATP, which is required for the process to continue working.
  
  

Nutrients

• The nutrients used during this cellular respiration process include amino acids, fatty acids, glucose, oxygen as an oxidizing agent, archea and bacteria. All of nutrients in this process are released as waste.
