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: Kidney
Explanation: The Kidneys produce the hormone in response to cellular hypoxia due to loss of blood.
Answer:
Proten W
Explanation:
SDS-PAGE gel is a method used for the separation of proteins in which proteins are separated based on their length (smaller proteins move faster through the gel, due to less resistance).
When treated with proteolytic enzymes, proteins are cut and become short fragment. This means that the fragments formed after the use of proteolytic enzymes, will move faster and thus, migrate a longer distance. Proteolytic enzymes in Set 2 cells will act only on plasma membrane proteins (because they cannot penetrate), while in Set 2 they will act on both, plasma membrane and interior proteins. Control group will have only the large fragments (not treated with enzyme).
Protein W travels the same distance on a gel of proteins from Set 1 and Set 2, but different than control group. It means that the proteolytic enzyme worked the same on Set 1 and Set 2.
