Question

volved Co, in respiration​

Answer 1

sorry question is not clear

Explanation:

yes, CO2 is involved in respiration

Answer 2

$\huge\bold{Evolution}$

Owing to its role in oxidizing reduced organic compounds to CO2, respiration is often considered catabolic and respiratory CO2 evolution as wasteful for plants. Therefore, there have been attempts to select plants with lower respiration to improve productivity. Genetic modification of respiratory enzymes confirms that respiration is important in growth and maintenance. For example, glycolysis is crucial for root growth. The oxidative pentose phosphate pathway is essential in supplying reduced nicotinamide adenine dinucleotide phosphate for defense mechanisms against pathogens. The tricarboxylic acid (TCA) cycle is indispensable for reproductive growth, biosynthesis of metabolites such as lipids, and productivity.
