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

the remaining chromosomes are known as autosomes
Answer:
The vessels draining Myocardium of the heart join to form <u>Coronary Sinus </u> that ultimately opens into <u><em>THE RIGHT ATRIUM.</em></u>
Explanation:
<u><em>CORONARY CIRCULATION:</em></u>
The heart muscles are called as Myocardium. Circulation of myocardium is known as Coronary Circulation. The heart needs to work continuously and requires an uninterrupted supply of blood.
<u>Coronary Arteries</u> supply oxygen rich blood to the myocardium and <u>Coronary Veins</u> remove deoxygenated blood from heart muscles and join to form Coronary Sinus that ultimately drains into the Right Atrium of heart. Some veins from the myocardium also drains directly into the right atrium.
