Bacteria convert atmospheric nitrogen to which of the following in the process of nitrogen fixation?
DiKsa [7]

Q1) Bacteria are capable of converting atmospheric N in the form of N2 gas to NH3. this process is known as nitrogen fixation. N2 in the atmospheric form is not usable by other organisms, therefore specialised bacteria such as Azetobacter species are capable of carrying out this conversion from N2 gas into NH3 form that can be used by other organisms 


Q2) Condensation.

Water in the gaseous state or known as vapour state converted to liquid state, process is known as condensation. in condensation the particles in water become more tightly packed and heat energy is removed from these particles reducing their kinetic energy thus becoming liquid state


Q3) 

Transpiration declines

Deforestation is when the number of trees and plants have been cut down therefore numbers have reduced drastically, transpiration is the process in which water is transported through the plant and lost to the environment through evaporation. When the trees and plants have reduced the water lost by way of transpiration is also reduced. This impacts the water cycle as the number of water being cycled in the environment is lesser now.


Q4) the sun

sun is the major source of energy that facilitates the recycling of water in the water cycle. The sun causes water to be evaporated from water bodies and converted to water vapour. This water vapour is then recycled.


Q5) Plants can’t use Nitrogen in the form of N2

N is an essential element needed by plants, however plants cannot use up the atmospheric N2 gas. therefore bacteria are capable of nitrogen fixation that converts N2 gas into forms that can be used up and absorbed by the plants from soil.

Which of the following enzymes are involved in coupled reactions in glycolysis? (Select all that apply.) Phosphoglycerate kinase
Len [333]

Answer:

Hexokinase, Phosphofructokinase, Phosphoglycerate kinase and Pyruvate kinase

Explanation:

Coupled reactions are reactions that require energy by one process and is supplied by another; where the energy is transferred from one side of the reaction to the other.

In glycolysis, four (4) reactions undergo coupled reactions

1. Reaction one: which is the phosphorylation of glucose to glucose-6-phosphate coupled to the hydrolysis of ATP to ADP and Pi catalyzed by hexokinase.

2. Reaction three: The phosphorylation of fructose-6-phosphate to fructose-1-6-bisphosphate and the hydrolysis of ATP, catalyzed by phosphofructokinase

3. Reaction seven: Phosphoglycerate kinase catalyzes the conversion of Bisphoglycerate to 3-phoshoglycerate and the production of ATP from ADP

4. Reaction ten: Pyruvate kinase catalyzes the conversion of enol phosphate to the enolic form of pyruvate with the synthesis of ATP.
