Some always remains in the form of urea, uric acid, or creatinine. 3 Cal/g, are excreted in the urine. 3 Cal/g from protein. Generally, nutritionists round off energy values and say that carbohydrates and proteins release about 4 Cal/g and fats provide 9 Cal/g. SNACK FOODS Your favorite aisles at a supermarket may be the ones with the snack foods, desserts, and candies. In fact, those aisles are probably the favorite ones for many people. Most everyone can recall a day when they devoured a large container of popcorn at the movies, downed a whole bag of pretzels at a picnic, or ate a bowl of potato chips while watching television.

Consequently, heat is a useful way to measure energy. You can measure heat in units known as calories. A calorie is the quantity of heat required to raise the temperature of 1 gram (g) of water by 1 degree Celsius (°C). If you add heat to water, the water’s temperature will rise. If you remove heat from water, its temperature will fall. If the temperature of 1 g of water rises 1°C, 1 calorie of heat has been added to the water. If the temperature of 10 g of water rises 10°C, 100 calories of heat have been added.

Because green light is reflected instead of being absorbed, most leaves appear green. A pigment is a colored substance. The green pigment in plant cells that is essential to photosynthesis is chlorophyll. Chlorophyll absorbs light, which is converted to the energy stored in molecules of starch during photosynthesis. Any excess sugar produced in a leaf is changed to starch and stored. You can use a common test for starch to confirm that food is produced in leaves when light, carbon dioxide, and water are present.
