A typical serving (1 medium, 182 g) has about 95 calories, and 100 g has 52 kcal. Calories scale with weight, so double the portion means double the number.
There are 0.3 g of protein in 100 g of apple, which works out to about 0.5 g per serving (1 medium). Treat it as an energy source rather than a protein source.
Sugar comes to 10.4 g per 100 g, so 1 medium (182 g) delivers roughly 19 g. That sugar is already counted inside the calorie figures on this page.
