- Chemical Energy and ATP
- One of the most important compounds that cells use to store and release energy is called adenosine triphosphate (ATP).
- It is a nucleoside triphosphate used in cells as a coenzyme. It is often called the "molecular unit of currency" of intracellular energy transfer. It transports chemical energy withing cells for metabolism.
- Cells can release the energy stored in ATP by the controlled breaking of the chemical bonds between the second and third phosphate groups.
- Cells carry out active transport using ATP. Energy from ATP is needed for many cellular activities including active transport across cell membranes, protein synthesis, and muscle contraction.

- Methods of Getting Food
- An autotroph is an organisim that can produce its own food using water, light, carbon dioxide or other chemicals.
- Algae and phytoplankton are autotrophs.
- The process by which autotrophs use the energy of sunlight to produce high-energy carbohydrates(sugars and starches) that can be used as food is called photosynthesis
- Organisms that obtain food by consuming other living things are known as heterotrophs. Some consume plants while some consume other heterotrophs.
- Animals like humans are heterotrophs. Some plants like the venus fly trap are also heterotrophs.
