In what form is the energy derived from the food that we eat is stored in our body?

The correct answer is Glycogen

Key Points

• Glycogenesis:
  • The Biochemical process in which Glucose is converted into Glycogen in the liver is known as Glycogenesis.
  • The cell must have an excess of glucose for starting this process. Glucose is the starting molecule and is converted through the process of glycogenesis.
  • When the body does have readily available glucose, the body creates glycogen through the process of glycogenesis.
  • This process is activated during rest periods in the liver and also activated by insulin in response to high levels of glucose.
  • When the body gets an excess meal and the blood glucose levels are high, the pancreas releases insulin hormone to store glucose.
  • The fat in the human body is stored for long time energy but glycogen is not the same as fat.
  • When the blood glucose concentration has dropped, glycogen stores are often taken from meals. 

Important Points

• Glycogenolysis:
  • Glycogenolysis is the breakdown of the molecule glycogen into glucose.
  • Glycogenolysis occurs in muscle and liver cells when more energy needs to be produced. 
• Gluconeogenesis:
  •  Gluconeogenesis fulfil the needs for plasma glucose between meals.
  • Gluconeogenesis takes place in the liver and kidneys. Gluconeogenic substrates include glycerol, lactate, propionate, and certain amino acids. 
• Glycolysis:
  • Glycolysis is the metabolic process that breaks down glucose into pyruvic acid to produce energy.
  • This process occurs in the cytosol of the cell cytoplasm. Glycolysis is an oxygen-independent metabolic pathway.
