Protein has 4 calories per gram
Carbohydrate has 4 calories per gram too
Fat has 9 calories per gram
all nurtients have a particulal kj which for each carbohydrate, protein, fibre and fat.
Strawberrys are not a source of protein it is a source of Carbohydrate.
To calculate the energy available from a food, multiply the number of grams of carbohydrate, protein, and fat by 4,4, and 9, respectively. Then add the results together and that should be your answer.
The amount of protein (4 kcal/gram), carbohydrate (4 kcal/gram), and fat (9 kcal/gram) that is present.

You can't calculate how much protein is in the soup from these figures.
Protein can provide energy, but this is extremely inefficient. This is due to the fact that the energy it takes to make it usable as energy is almost as much as the energy it provides.
Bananas have a small amount of protein. One medium-sized banana contains about 1 gram of protein. However, bananas are commonly known for their potassium and carbohydrate content.
If you mean why: because it is a much more efficient way to store energy than, say, a carbohydrate. You would need twice the amount of carbohydrate molecules to give the same amount of energy.

Protein is needed for muscle growth and repair. Regular physical training tends to reduce muscle protein breakdown and protein loss from the body. While some protein breakdown may occur during exercise, protein build-up is enhanced during the recovery and the effectiveness of protein synthesis is increased. When muscle glycogen stores are high, protein contributes no more than 5% of the energy needed. However, when muscle glycogen stores are low, due to inadequate calorie and carbohydrate intake, protein is used for energy rather than for muscle growth and repair and may contribute as much as 10% of the energy needed for exercise. Such use of protein for fuel is expensive and inefficient.
