Verified By Collegedunia
The Correct Option is D
Solution and Explanation
In Krebs? cycle two decarboxylations occur at following steps:
$\underset{(6 - C)}{\text{Oxalosuccinate}} \ce{->[\text{ Oxalosuccinate}][\text{ decarboxylase}]} \underset{( 5 -C)}{\alpha - \text{ketoglutarate}} + CO_2$
$\underset{(5-C)}{\alpha - \text{ketoglutarate}} + NAD + Co-A \ce{->[\alpha - \text{keto glutarate}][\text{dehydrogenase}]}$
$\underset{(4-C)}{\text{Succinyl }Co- A } + NADH_2 + CO_2$
$\underset{(6 - C)}{\text{Oxalosuccinate}} \ce{->[\text{ Oxalosuccinate}][\text{ decarboxylase}]} \underset{( 5 -C)}{\alpha - \text{ketoglutarate}} + CO_2$
$\underset{(5-C)}{\alpha - \text{ketoglutarate}} + NAD + Co-A \ce{->[\alpha - \text{keto glutarate}][\text{dehydrogenase}]}$
$\underset{(4-C)}{\text{Succinyl }Co- A } + NADH_2 + CO_2$

Respiration in Plants
Respiration in plants is a process that entails the production of energy in plants. This process can simply be described as the intake of Oxygen and the release of Carbon Dioxide as an outcome of the oxidation of complex organic compounds. Though plants do not have any specific organ to balance the process of respiration, their stems, roots, and leaves do this work at a very low rate than other living beings. The process of respiration is very crucial for the plants to sustain the growth of the plant tissues.
This process can be stated as-
\[C_6H_{12}O_6 + 6O_2 → 6CO_2 + 6H_2O + \text{Energy}\]
