THE NUCLEUS, BECAUSE FIRST OF THE NUCLEUS CONTROLS MOST OF THE HEREDITARY INFORMATION OF DNA YOU KNOW WHAT IS RIGHT? (DEOXYRIBONUCLEIC ACID) WHICH IS FOUND ON THE CHROMOSOMES. ALL THE OTHER ORGANELLES THAT DOES THERE OWN FUNCTIONS ARE CONTROLLED BY THE NUCLEUS. FOR EXAMPLE:
NUCLEUS: HEY RIBOSOMES!!
RIBOSOMES: YEA BOSS?
NUCLEUS: GO TO THE ENDOPLASMIC RECTULUM AND PRODUCE PROTEINS THERE
RIBOSOMES: YOU GOT IT BOSS!
SEE.... RIBOSOMES PRODUCE PROTEINS FOLLOWING CODED INSTRUCTIONS THAT COME FROM THE NUCLEUS. "THE CONTROL CENTER"
Answer: A simple word equation that can be used to describe the process of photosynthesis is carbon dioxide + water —> glucose + oxygen + water. A balanced chemical equation for the process can be written as 6CO2 + 6H2O —> C6H12O6 + 6O2. Overall, photosynthesis uses light energy to convert carbon dioxide into a carbohydrate.
Explanation:
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
<span>Other mutagens act by chemically modifying the bases of DNA. For example, nitrous acid (HNO2) reacts with bases that contain amino groups. Adenine is oxidatively deaminated to hypoxanthine, cytosine to uracil, and guanine to xanthine. ... Uracil pairs with adenine rather than with guanine.</span><span>
