We get Instant Energy from Glucose because it is a simple sugar that can be easily absorbed by the body. A person who is low on energy is often advised to consume glucose. Unlike other foods like carbohydrates, our body doesn’t need to process glucose and it is directly absorbed into our bloodstream.
Instant Energy from Glucose
When glucose is absorbed into our bloodstream, it undergoes oxidation, which releases ATP, a high-energy molecule. Therefore, consuming glucose provides us with instant energy. Cellular respiration is the process through which glucose is oxidized.
Glucose is the most significant energy source in all species’ energy metabolism. For metabolism, glucose is stored as a polymer, mostly as starch and amylopectin in plants and glycogen in mammals. Animals’ blood contains glucose as blood sugar.
- D-glucose is the type of glucose created naturally, whereas l-glucose is synthesized in tiny amounts and has lower biological activity.
- German scientist Andreas Marggraf discovered glucose in 1747 while attempting to separate it from raisins.
- Another German chemist, Johann Tobias Lowitz, identified glucose as a substance distinct from sugarcane in grapes in 1792.
Summary:
Why do we get Instant Energy from Glucose?
Glucose is a simple sugar, which gives Instant Energy. The monosaccharide glucose has the molecular formula C6H12O6. Hence, the body doesn’t have to do much to absorb glucose into the bloodstream. Complex carbs, proteins, and lipids make up our diet. The digestive system’s enzyme converts them into less complex carbs. These carbs provide a quick source of energy. After glucose is absorbed, it releases ATP, which is the cause of instant energy.
