Pole strength is defined as the strength of a magnetic pole so as to attract magnetic materials towards itself. Pole strength is a scalar quantity.
| SI unit | N.Tesla-1 |
| Dimensions | [LA] |
Formula P = W/ I
Where,
- P is the Strength of the magnetic pole
- W is the work done while moving the magnet around the wire
- I is the electric current in the wire

- The first step of the Calvin pathway is the first CO2 fixation step.
- Respiration is the reaction where RuBP combines with CO2 to form 2 molecules of 3PGA, that is catalysed by RuBisCO.
RuBP + CO2 -> 2 X 3PGA
- RuBisCO has a much greater affinity for CO2 than for O2.
- In C3 plants, some O2 do bind to RuBisCO, and hence CO2 fixation is decreased.
- The RuBP instead of being converted to 2 molecules of PGA binds with O2 to form one molecule and phosphoglycolate in a pathway called photorespiration.
- In the photorespiratory pathway, there is neither synthesis of sugars, nor of ATP.

Biological catalysts:
The molecules.that can speed up the chemical reactions in cells is called a biological catalyst.
Example:
Enzyms as biological catalyst :
Enzyms are soluble protein molecules. They can speed up the chemical reactions in cells respiration,photosynthesis and making new protiens are include in this reaction. due to this reaction enzymes are some times called as biological catalyst.
In enzime catalized reaction, the substract is changed to the product via a high energy transition in the state. this state has a very short life cycle and it is stabilized by the enzyme
An example of this type of reaction is decomposition of hydrogen peroxide into water and oxygen. Although the reaction is strongly favored thermodynamically, it is very slow unless catalyzed

Nitrogen fixation occurs in the root nodules that contain bacteria ( Bradyrhizobium for soybean, Rhizobium for most other legumes). Almost all legumes can fix nitrogen. The legume family (Leguminosae or Fabaceae) includes many important crop species such as pea, alfalfa, clover, common bean, peanut, and lentil. rankia is a genus of soil actinomycetes in the family Frankiaceae that fix nitrogen, both under symbiotic and free-living aerobic conditions, while most rhizobia do not (Benson and Silvester, 1993).
