For prolonged low-intensity activity, fat is the ideal source of energy. The body utilizes fatty acids during extended periods of aerobic exercise, as they provide a more sustained energy release compared to carbohydrates. This metabolic process allows for endurance over long durations, making fat the preferred fuel for activities like long-distance walking or jogging.
Carbohydrates
If the length of an activity exceeds 150 seconds, the aerobic energy system becomes the predominant source of energy. This system relies on oxygen to convert carbohydrates and fats into energy, supporting sustained physical activity. In contrast, shorter bursts of activity primarily utilize the anaerobic energy systems, which do not require oxygen but can only sustain energy production for limited durations. Thus, for prolonged activities, the aerobic system is essential for maintaining performance.
Cooking uses heat energy as the main source. It is the main activity that uses heat as a source of energy.
Muscles store glycogen as a source of energy for physical activity. Glycogen is a form of glucose that is stored in muscle cells and can be quickly converted into energy when needed during exercise. This stored glycogen helps muscles maintain their strength and endurance during prolonged physical activity.
Glycogen serves as a quick energy source during exercise by providing glucose to fuel muscle activity. As the body engages in physical activity, stored glycogen in the muscles is broken down into glucose for energy production. Efficient glycogen utilization allows for prolonged exercise performance before fatigue sets in.
The increased use of fats as an energy source typically occurs during prolonged physical activity or exercise, especially when carbohydrate stores are depleted. It also happens during periods of fasting, low-carbohydrate diets, or caloric restriction, as the body shifts to fat metabolism for energy. Additionally, adaptations such as increased fat oxidation can develop with endurance training.

Volcanic activity can be an excellent source of geothermal energy, it can act as a fertilizer for the soil too. hope this helps
The body utilizes fat efficiently as a fuel source during low to moderate-intensity exercise, particularly when glycogen stores are depleted. This process is more pronounced when the body is well-adapted to utilizing fat, such as in trained athletes or during prolonged physical activity. Additionally, when carbohydrate intake is low, the body shifts towards fat oxidation for energy, especially during fasting or ketogenic states. Overall, fat is a primary fuel source when energy demands are steady and prolonged.
Fat is a form of energy reserve in the body, primarily stored in adipose tissue. It serves as a crucial source of energy during periods of fasting or prolonged physical activity. Additionally, fat helps to insulate and protect vital organs, as well as plays a role in hormone regulation and nutrient absorption.
A concentrated source of energy that is more efficient than carbohydrates is fats. Fats provide approximately 9 calories per gram, compared to carbohydrates, which offer about 4 calories per gram. This higher energy density makes fats a vital energy reserve for the body, especially during prolonged physical activity or periods of fasting. Additionally, fats play essential roles in hormone production and cellular structure.
Carbohydrates are the primary nutrient used as a source of energy. They are broken down into glucose, which is readily utilized by the body for immediate energy needs. Fats also serve as an important energy source, particularly during prolonged low-intensity activities, while proteins can be used for energy in certain circumstances, but their main role is in building and repairing tissues.
