Some early uses for carbon include making ink, black pigment for art, and creating black powder for fireworks. Carbon has also been used as a filter for purifying water and as a source of fuel for fires and heat.
Green sulfur bacteria have bacteriochlorophylls and use alcohols such as ethanol or methanol as a carbon source for photosynthesis. They have adapted to low-light environments where they thrive by utilizing these alternative carbon sources.
The process that uses oxygen to make carbon dioxide is called cellular respiration. In this process, cells break down glucose molecules to produce energy, carbon dioxide, and water.
A particle of carbon is an atom of carbon, which is the smallest unit of a chemical element composed of protons, neutrons, and electrons. Carbon atoms can combine to form different structures, such as graphite and diamond, with various properties and uses.
Burning uses oxygen to produce carbon dioxide. During combustion, when a material reacts with oxygen, it releases carbon dioxide as a byproduct.
Yes, aerobic respiration uses oxygen as the final electron acceptor in the electron transport chain. It produces carbon dioxide as a byproduct of the process along with water and energy in the form of ATP.
