energy, glucose, and fats

Detailed explanation-1: -The primary fuel for cellular respiration is glucose. Fats can be broken down to make ATP. Proteins and nucleic acids can also be used to make ATP, but they are usually used for building important cell parts. In glycolysis, enzymes break down one six-carbon molecule of glucose into two three-carbon pyruvate molecules.
Detailed explanation-2: -The most common respiratory substrate is glucose, which has a 6-carbon compound. The substrate is metabolized through glycolysis, the TCA cycle, electron transport chain, and oxidative phosphorylation.
Detailed explanation-3: -Fats are a substrate for cellular respiration. It gives the highest amount of energy among fats, carbohydrates, and proteins. Fat is a triglyceride molecule. Triglyceride is degraded to fatty acid and glycerol.
Detailed explanation-4: -In your body, glucose is the form of energy that is carried in your blood and taken up by each of your trillions of cells. Cells do cellular respiration to extract energy from the bonds of glucose and other food molecules. Cells can store the extracted energy in the form of ATP (adenosine triphosphate).
