Bacteria are important in the soil to maintain the nitrogen cycle. Certain type of bacterais help in nitrogen fixation. They also decompose dead and decaying matter into nitrogen compounds such as ammonia. The nitrogen and nitrogenous compounds in turm help the plant to grow.

When the plant dies, the bacteria again decomposes it into nitrogenous compounds. Not only plants, but also animals. The nitrogen then passes through various stages and then gets back to atmospheric nitrogen. Bacteria is an important part of this nitrogen cycle.

g when hydrogen is present and the citric acid cycle is active, the ph of the mitochondrial matrix is
11111nata11111 [884]

Answer:

The pH remains constant

Explanation:

The pH value of Mitochondrial matrix = 7.8 while the pH of the intermembrane space of the mitochondria = 7.0–7.4

The presence of the hydrogen atoms makes the mitochondrial matrix acidic and hence reduced the pH value but the pH of inner and outer matrix is maintained equal to each other thus as the H+ ion increases, the base concentration increases thereby pushing H+ to the inter membrane space and hence producing ATP.
