- competitive inhibition
- non-competitive inhibition
- feedback allosteric inhibition
- positive feedback.
Hide Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Competitive inhibition is the reversible inhibition of enzyme activity due to presence of substrate analogues. Non competitive inhibition is the reduction of enzyme activity by a factor that has no real structural similarity with the substrate. Allosteric inhibition is reversible noncompetitive inhibition occurring in case of allosteric enzymes. Herein, the inhibitors are the products or intermediates of reactions are catalyzed by the enzymes. Hence, it is also called end product inhibition or feedback inhibition.

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-
\[C_6H_{12}O_6 + 6O_2 → 6CO_2 + 6H_2O + \text{Energy}\]
