How during a marathon race the blood glucose concentration stays fairly constant but the mass of glycogen in the liver decreases?
During a marathon, the body primarily uses glycogen stored in the liver and muscles for energy. As the race progresses, glycogen stores deplete, leading to a decrease in liver glycogen levels. However, blood glucose concentration remains relatively constant due to the liver's ability to release glucose into the bloodstream through gluconeogenesis and glycogenolysis, as well as the hormonal regulation of insulin and glucagon. This mechanism ensures that the muscles continue to receive a steady supply of glucose for energy, despite the declining glycogen reserves.
What else can I help you with?
Why does a marathon runner eat a large starchy meal before a bi g race?
The large starchy meal allows the runner to store large amounts of glucose in the body in the form of glycogen. All these glycogen would be converted to glucose when he needs them in large amount during the race. The glucose converted can help him when his muscles undergo aerobic or anaerobic respiration.
What biological macromolecule would be useful if you were running a marathon?
Carbohydrates would be the most useful biological macromolecule for running a marathon as they provide a quick source of energy to fuel the muscles during endurance activities. Consuming complex carbohydrates before the race can help store glycogen in the muscles for sustained energy, while simple carbohydrates during the race can provide immediate energy.

What is the energy mechanism used in the second hour of running a marathon?
During the second hour of running a marathon, the body relies on a combination of aerobic metabolism and muscle glycogen stores to provide energy. Aerobic metabolism breaks down carbohydrates and fats to produce ATP, while muscle glycogen stores are accessed to fuel muscle contractions. The body also starts to shift towards fat metabolism to conserve glycogen stores for later stages of the race.
What high carb foods are good for eating before running a marathon?
Pasta and potatoes contain Glycogen which helps to maintain your energy levels when training for a marathon. Stay away from too many fruits and juices as those can cause stomach problems.
The energy mechanism used in the second hour of running in a marathon?
During the second hour of running in a marathon, your body primarily relies on stored glycogen in the muscles and liver for energy. As you continue to run, your body starts to use stored fat for energy as well. The shift to burning more fat helps conserve glycogen stores and prolong endurance during long-distance running.
