A. glycolysis
B. oxidative phosphorylation
C. chemiosmosis
D. fermentation
E. photosynthesis

Option D) fermentation

In yeasts and certain other microbes going through fermentation, pyruvate is turned into ethyl alcohol (ethanol).

Explanation:

Under anaerobic conditions (in the absence of oxygen), organisms such as yeast and microorganisms convert pyruvate (the end product of glycolysis) into ethanol and carbon dioxide ( CO2 ).

Thus, the process of turning pyruvate to alcohol is known as alcoholic fermentation.

step 1 ammonium can be absorbed by plants, but some is converted into nitrates which are better for plants to absorb. this is called nitrification. 2. step 2 the deer eats the plants and uses the nitrogen-containing proteins for cell growth. 3. step 3 bacteria in the soil conduct nitrogen fixation to convert nitrogen gas from the atmosphere into ammonium. 4. step 4 some of the nitrates are absorbed back into plants, but denitrification breaks down the nitrates into nitrogen gas released back into the atmosphere. 5. step 5 nitrogen is found in the urine, which gets broken down into ammonium through the process of ammonification. 6. step 6 plants absorb the ammonium and begin assimilation, the process to add the nitrogen to protein.

the cell cycle is the final answer! : )
