The fat in adipose cells is broken down into fatty acids. which pathway is involved in this process? a: a catabolic pathway
b: an anabolic pathway
c: catabolic and anabolic pathways

The correct answer is a: A catabolic pathway.

The catabolic reactions breaks down the large organic molecule to smaller molecules thus releasing energy contained in the chemical bonds of the larger molecules. The fatty acids stored in the form of triglycerides are released from the fats that are deposited in the adipose tissues in between the meals.

The fatty acid catabolism includes lipolysis which removes the fatty acid chains or the triglycerides into glycerol and other small chain fatty acids.The β- oxidation process occurring the matrix of mitochondria breaks the long chain fatty acids finally to the acetyl-coA molecules. In each cycle of the β-  oxidation 5 ATP molecules are released at the end.

"-the movement of carbon from the nonliving environment into living things and back to the environment

-carbon is the essential component of proteins, fats, and carbohydrates (which make up all organisms)

-carbon exists in air, water, and living organisms

-producers convert carbon dioxide in the atmosphere into carbohydrates during photosynthesis

-bacteria in the atmosphere cycles through the system in filtration units

-in cellular respiration, carbon is released back into the atmosphere as carbon dioxide

-some carbon is stored in limestone (forming one of the largest "carbon sinks" on earth)

-largest carbon reservoir on earth= limestone

-carbon stored in the bodies of organisms as fat, oils, or other molecules may be released into the soil or air when the organism dies

-this may form deposits of coal, oil, or natural gas (fossil fuels, which increased the atmospheric carbon dioxide)

-fossil fuels store carbon left over from bodies of organisms that died millions of years ago

-they are located in the surface of earth, deep within the earth and beneath the ocean floor."
