Carbohydrates are instant source of energy it breaks into glucose. Fats provides more energy as compared to proteins nd carbohydrates.

Carbohydrates only

Carbohydrates are regarded as a source of instant energy. When we consume carbohydrates, they are broken down into glucose, which is the primary source of fuel for our body. Glucose is readily available for immediate use by our cells, making carbohydrates the preferred source of energy for our body.

Explanation:
Carbohydrates are the most efficient source of energy for the body due to their quick breakdown and utilization. Here is a detailed explanation of why carbohydrates are regarded as a source of instant energy:

1. Quick digestion and absorption:
Carbohydrates are quickly broken down into glucose during digestion. Glucose is then absorbed into the bloodstream and transported to the cells. This rapid digestion and absorption process provide a quick energy boost.

2. Glycogen storage:
Excess glucose is stored in the liver and muscles in the form of glycogen. When needed, glycogen can be rapidly broken down into glucose to provide an immediate energy supply.

3. ATP production:
Glucose is the primary fuel for ATP (adenosine triphosphate) production. ATP is the energy currency of the body, and it is required for various cellular processes. When glucose is metabolized, it generates ATP, which is used by cells to perform their functions.

4. High energy yield:
Carbohydrates provide approximately 4 calories per gram, which is a higher energy yield compared to fats and proteins. This means that a smaller amount of carbohydrates can provide a larger amount of energy.

5. Availability:
Carbohydrates are found in a wide variety of foods, such as grains, fruits, vegetables, and legumes. They are readily available and easily incorporated into meals and snacks, providing a quick and convenient source of energy.

Conclusion:
In conclusion, carbohydrates are regarded as a source of instant energy due to their quick digestion, glycogen storage, ATP production, high energy yield, and availability. Consuming carbohydrates as part of a balanced diet ensures that our body has a readily available energy source to support various physiological functions and physical activities.
