Answer: a) substrate and cofactors b) covalent modification
Explanation:
Metabolic pathways involve all the chemical processes takes place in the enviornment or in an organisms.The metabolic pathways are controlled through the catalytic activities of enzymes.
The availability of enzyme is regulated by substrate and cofactors present in enzyme and enzyme activity is commonly regulated via covalent modification.
Enzymes are highly selective in nature and bind to a specific substarte only. The active site in enzyme binds with the substrate to form enzyme substrate complex. Coactors assist the enzyme activity, without cofactor enzyme can not perform its activity.
Hence enzyme availibility is regulated by substrate and cofactors regulates.
Covalent modifications regulates activity of enzyme as it involves addition and removal of chemical group to synthesis required protein. It can change the chemical properties of the site by targeting one or multiple amino acid.
Thus the correct answer is a) substrate and cofactors b) covalent modification
Answer: Option a
Explanation:
Biotechnology is the branch which deals with the most advanced techniques which is required to make the life easy.
One of the most important application is Genetically modified crops. Genetically modified crops are pest resistant and have many advantages.
There are few disadvantages one of them is beneficial insects are also adversely affected. There are many useful insects that helps in pollination and they are also killed because of pest resistant plant.
hence the correct answer is option A
