The energy for ATP synthesis comes from organic molecules (such as carbohydrates), or from sunlight, or from inorganic electron donors. We can classify organisms according to their source of energy and organic carbon:
<span><span>heterotrophs – get energy and organic carbon from metabolism of pre-existing organic compounds (food)</span><span>photoautotrophs – use energy from sunlight to make ATP and their own organic carbon compounds from carbon dioxide chemoautotrophs</span><span> – use energy from inorganic chemicals to make ATP and their own organic carbon compounds from carbon dioxide</span></span>
Metabolic pathways carry out reactions that capture energy from these various sources (organic compounds, sunlight or chemicals) and couple them to synthesis of ATP from ADP.
Daughter cells are cells which are genetically identical to parent cells because they have the same type and number of chromesomes
Exposure to radioactive material or liquids

Explanation:
The half-life of C-14 is shorter than that of U-238. Every radioactive isotope have their distinct and unique half-life.
- The half-life of an isotope is the time taken for half of the radioactive nuclei to disintegrate.
- The shorter the half-life, the faster an isotope decays.
- C-14 has an half life of 5700 years. It is used for dating archaeological materials.
- U-238 has an half life of 4.5 billion years. It has been used to date the age of the earth.
