Question

Living organisms and the remains of once living organisms actually store quite a bit of energy. This energy is stored in the forms of:

a. ATP
b. chemical bonds of organic compounds
c. sunlight and photons
d. proton gradients (as potential energy)
e. a combination of all above.

Answer 1

Energy in living organisms is primarily stored in chemical bonds of organic compounds, which is transformed into ATP, a readily usable form of energy for cellular work.

Step-by-step explanation:

The energy stored in living organisms and the remains of once-living organisms is principally stored in the form of chemical bonds of organic compounds. These compounds, such as sugars and fats, contain chemical energy within their molecular bonds, which can be transformed through cellular processes into energy within ATP (adenosine triphosphate) molecules. The energy in ATP is readily available for cells to do various types of work, including building complex molecules, transporting materials, powering the motion of cilia or flagella, contracting muscle fibers for movement, and reproduction.
