If you could attach fluorescent marker tags to the enzyme that transfers the acetyl group from acetyl coa to oxaloacetate, and then detect that fluorescence with a powerful microscope, in which part of a cell would you predict to observe the fluorescence?

The fluorescence would be observed in the mitochondrial matrix.

We can arrive at this answer because:

In this case, we can state that both the fluorescence-labeled enzyme and the reaction it promotes occur in the mitochondrial matrix, being the place where we could see the fluorescence.

The fluorescence marker tags to the enzyme when see with a powerful microscope the fluorescence will be observed in the mitochondrial matrix of the cell.

Explanation:

The enzyme responsible for the transfer of acetyl CoA group to oxaloacetate is  ATP citrate lyase. It is produced in the matrix of the mitochondria in the cell during aerobic respiration.

The transfer of acetyl CoA group to oxaloacetate group marks start of the Kreb's cycle which also occurs in the matrix of mitochondria.

Hence the enzyme ATP citrate lyase when tagged with fluorescence will be seen in mitochondria of the cell.

"-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."
