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.

Volcanic activity can be an excellent source of geothermal energy, it can act as a fertilizer for the soil too. hope this helps
Fat , I use the example of the camel whose hump is a fatty energy source. Fat , I use the example of the camel whose hump is a fatty energy source.
True. Fat is the nutrient with the highest concentration of energy, providing approximately 9 calories per gram, compared to carbohydrates and proteins, which each provide about 4 calories per gram. This high energy density makes fat an important source of fuel for the body, especially during prolonged physical activity.
No, geothermal energy availability depends on location. In areas with active tectonic plates or volcanic activity, geothermal sources are more readily available. Conversely, in regions with less geothermal activity, accessing this energy source may be more challenging.
Waves get their energy from a source that causes disturbances or vibrations. This source could be wind, seismic activity, or the movement of objects in water. The energy is transferred through the medium in which the waves are traveling, leading to the propagation of waves.
Lipids are a highly efficient source of energy that can provide a sustained fuel source for cellular activity. However, carbohydrates are usually the body's preferred source of energy due to their quicker conversion to ATP, the cell's primary energy currency. Lipids are typically used during longer periods of low-intensity activity or when carbohydrate stores are depleted.
