Photorespiration is useful for plants as it:
1) Protects plants from photo-oxidative damage
2) Provides net gain 2 ATP
3) Enable RuBisCO to show its oxygenase activity
4) Increase rate of C O 2 fixation

A

Protects plants from photo-oxidative damage

B

Provides net gain `2` ATP

C

Assertion : Under conditions of high light intensity and limited CO_(2) supply, photorespiration has a useful role in protecting the plants from photo oxidative damage. Reason If enough CO_(2) is not avilable to utilize light enregy for carboxylation to proceed, the excess energy may not cause damage to plants.

Assertion : Photorespiration is found in all plants Reason : In C_(4) plants, first CO_(2) fixation product is formed in bundle sheath cells

A : Tropical plants are more efficient in CO_(2) untilization. R : C_(4) plants ensure that RuBisCO functions as carboxylase minimising oxygenase acitivity.

Assertion : Photorespiration is a useful process where there is no synthesis of ATP energy. Reason : RuBisCO is present in mesophyll cells of C_(4) plants, hence they show more productivity.

Find the correct answers : For germination of angiospermic seeds 1 On hydration the seed germinates showing increased enzyme activity 2 Respiration rate of germinating seeds increases alongwith increased enzymatic acitivity 3 Increase in respiratory rate continues till senescence 4 Rate of enzymatic activity increases

The following is not relate to C_4 plant Water use efficiency is more Photorespiration is not detectable CO_2 compensation points is high The primary acceptor of CO_2 is a 3C compound

In an agriculture experiment, a solution containing 1 mole of a radioactive meterial (t_(1//2)=14.3 days) was injected into the roots of a plants.the plant was allowed 70 hours to settle down and then activity eas measured in its fruit. If the activity measured was 1 mu Ci what per cent of activity is transmitted from the root to the fruit in steady state?

The oxidation number of an element in a compound decides its nature to acts as oxidant or reductant. Oxidation number is defined and the residual charge which an atom has or appears to have in a molecule whenal other atoms are removed from the molecule as ions. Oxidation number is frequently used interchangebly with oxidation state. The stock notations of oxidation number are based on the periodic property-electronegativity. An atom in a molecule can be assigned positive, negative or zero oxidation number by considering its environment. In few cases, oxidation number can evenn be fractional. Oxidation number of oxygen in K_(2)O, K_(2)O_(2),KO_(2),KO_(3) are in the order:
