BIOMOLECULES AND ENZYMES

Detailed explanation-1: -The energy content of all food molecules can be traced back to the Sun. It is the process of photosynthesis that locks the Sun’s energy into simple carbohydrates like glucose.

Detailed explanation-2: -All nutritional energy comes from the Sun: plants use chlorophyll to photosynthesize the Sun’s energy into plant energy, and then animals either feed on plants for that energy or they feed on the animals that have eaten that plant energy. The food chain begins with the Sun and then the energy flows to producers.

Detailed explanation-3: -The sun generates energy from a process called nuclear fusion. During nuclear fusion, the high pressure and temperature in the sun’s core cause nuclei to separate from their electrons. Hydrogen nuclei fuse to form one helium atom. During the fusion process, radiant energy is released.
