Summarize the nitrogen cycle and it’s importance of proteins and DNA
iren2701 [21]

Answer:

Nitrogen cycle works through various stages like, nitrogen fixation, nitrification, assimilation, ammonification, denitrification etc. It is a building block for protein and DNA

Explanation:

Nitrogen is an element abundantly found in the atmosphere, also its building block for proteins as well as nucleic acid i.e. DNA formation. In nitrogen cycle , the nitrogen is being prepared from inert nitrogen.  The nitrogen cycle has several processes like nitrogen fixation, in this the inert nitrogen is being converted to organic nitrogen with the help of certain micro-organism.

Nitrification, plants cannot absorb directly nitrogen so bacteria help the plants to convert the nitrogen into ammonia form in this stage. Assimilation, another stage in which plants starts absorbing various forms of nitrogen from the soil.i.e. nitrate, nitrite and ammonium. Ammonification, here plants and animals have nitrogen in there body after death various microbes help in decomposition in this stage. Denitrification, in this stage the return back of nitrogen takes place.

A glucose molecule is completely broken down to carbon dioxide and water in glycolysis and the citric acid cycle. True or False
lutik1710 [3]

Answer:

True

Explanation:

A glucose molecule enters glycolysis in the cytoplasm of the cell. The glycolytic reactions break down one molecule of glucose into two molecules of pyruvate. Each of the pyruvate molecules is then decarboxylated and is oxidized into acetyl CoA. Acetyl CoA enters Kreb's cycle. Acetyl CoA is completely broken down into CO2 and H2O in Kreb's cycle. In this way, glycolysis and Kreb's cycle break down the glucose molecule into CO2 and H2O in a stepwise manner.
