unlike the liver and skeletal muscles, the brain does not store large amounts of glycogen. how does the body supply glucose to the brain during periods of fasting?

Sagot :

The brain only relies on sugar molecules so during the fasting stage after glucose is used up, fat is the next source of energy. Fat is a breakdown of fatty acids into energy.

Under normal conditions, glucose (sugar) from food is stored in the liver and muscles as the main source of energy. Before entering the fasting phase, the body will burn this energy source so that we can carry out activities as usual. After glucose runs out, fat is the next source of energy. Our bodies, which used to burn glucose, now switch to metabolizing fat during fasting.

We need to know about the metabolic processes during fasting so we can understand that the human body has natural mechanisms that are used to overcome unwanted conditions so that they remain in normal conditions. This natural mechanism is known as homeostasis. The body of the fasting person is not supplied with food, but the body will survive. This is because the body still has energy reserves in the form of fat, which comes from carbohydrates stored in the form of glycogen.
