The ability to store excess energy is an evolutionary adaptation that helps animals deal with mobility and food shortages. Information presented and the examples highlighted in the section support concepts outlined in Big Idea 2 of the AP ® Biology Curriculum Framework.
Food energy is defined as the energy released from carbohydrates, fats, proteins, and other organic compounds. When the three major calorigenic nutrients (carbohydrates, fats, and proteins) in a food are burnt entirely with sufficient amounts of oxygen, it releases energy or food calories that are expressed in kilojoules (kJ) or kilocalories ...
Food is a store of energy, transferred from the food to the consumer. 'Food energy' is measured in joules ( J ) or kilojoules ( kJ. Food types (groups) have different amounts...
In this article, you will learn about how we obtain energy from food according to the Singapore Primary 6 Science Syllabus. You will understand that living things need energy to carry out life processes and they obtain energy from the food they eat.
Food energy is chemical energy that animals (including humans) derive from their food to sustain their metabolism, including their muscular activity. [1] Most animals derive most of their energy from aerobic respiration, namely combining the carbohydrates, fats, and proteins with oxygen from air or dissolved in water. [2] .
During the chemical reactions of photosynthesis, energy is provided in the form of a very high-energy molecule called ATP, or adenosine triphosphate, which is the primary energy currency of all cells.
