Briefly describe the source and destination of blood sugar?

What people often call blood sugar refers to the content of glucose in the blood. Glucose is a very important source of energy for the human body. When people are active, especially when doing strenuous exercise, the body needs to consume a lot of energy, so the glucose in the blood will continue to be consumed, and then blood sugar can be replenished through diet and fat decomposition. The following is a detailed introduction to the source and destination of blood sugar.

Briefly describe the source and destination of blood sugar:

Blood sugar refers to the glucose in the blood, which has three main sources: food digestion and absorption into the blood, glycogen stored in the liver or muscles converted into glucose entering the blood, and non-carbohydrates (protein, fat) converted into glucose through gluconeogenesis.

There are three main ways for it to go: it is directly taken up by the body's cells for energy, it enters the liver or muscles and is converted into glycogen for storage, and it is converted into fat storage in adipose tissue.

There are three main sources of blood sugar in normal people. ① After a meal, the sugar in food is digested into glucose and absorbed into the blood circulation, becoming the main source of blood sugar. ② When fasting, blood sugar comes from the liver. The liver stores glycogen, which breaks down into glucose and enters the blood when fasting. ③Protein, fat and lactic acid produced from muscles can be converted into glucose through the process of gluconeogenesis.

There are five main pathways for blood sugar in normal people. ①The main destination of blood sugar is oxidation and decomposition into carbon dioxide and water in tissue cells throughout the body, while releasing a large amount of energy for the human body to use and consume. ②Enter the liver and become glycogen and stored. ③Enter muscle cells and become glycogen for storage. ④Converted into fat and stored. ⑤Transformed into components of cells.

Sugar in food ------ digestion, absorption ------ blood sugar

Glycogen------------decomposition-------------blood sugar

Fat and other non-sugar substances----conversion-------------blood sugar

Blood sugar--------oxidative decomposition--------CO2+H2O+energy

Blood sugar--------Synthesis------------liver glycogen, muscle glycogen

Blood sugar--------converts------------to fat, certain amino acids, etc.
