Answer:
The pair of terms whose relationship is very similar to the relationship between catabolism and anabolism are exergonic and endergonic.
Explanation:
Anabolism and catabolism are processes that occur in matabolism, whose result is different.
- <u><em>Anabolism </em></u><em>involves all the processes of manufacture or synthesis, in which chemicals are bound together to form new compounds. This process consumes energy, so it is called </em><em>endergonic</em><em>.
</em>
- <u><em>Catabolism</em></u><em>, unlike anabolism, is the process of degradation of complex molecules into simple molecules. One of the results of catabolism is the release of energy, which is equivalent to saying that it is an </em><em>exergonic</em><em> process.
</em>
Relating catabolism to anabolism is similar to relating exergonics to endergonics.
<em> The other terms do not represent a similarity with the relationship between the processes of catabolism and anabolism.</em>
Opsonization.
Explanation:
- Complement proteins and antibodies coat a microorganism and provide binding sites, enabling macrophages and neutrophils to phagocytize the organism. This phenomenon is termed opsonization.
Opsonization occurs as a result of binding of a molecule called opsonin to the epitope of a pathogen.
Opsonization helps the immune system to select and kill the infected cells instead of targeting all the cells in general.
Corpus Callosum is a band of thick fibres which connects the hemispheres of the brain.
Answer:
C. The enzyme with mutation 1 has decreased affinity for pyridoxal phosphate, whereas the enzyme with mutation 2 has lost the ability to bind to the substrates.
Explanation:
A coenzyme is an organic cofactor that binds with an enzyme in order to initiate or aid the function of the enzyme. A coenzyme binds to the active site of the enzyme (where the reaction occurs), thereby triggering its activation by modifying protein structure during the reaction. Some examples of coenzymes include Coenzyme A and Adenosine triphosphate (ATP). Pyridoxal phosphate is a coenzyme (it is the active form of vitamin B6) that is required for the function of cystathionase. Moreover, cystathionase is an enzyme that enables cells the synthesis of cysteine from methionine (transsulfuration pathway). The binding of pyridoxal phosphate to the enzyme increases the binding affinity of the enzyme for the substrate, thereby influencing its activity. In this case, it is expected that mutation 1 reduces the binding affinity of the enzyme to the cofactor, and thereby the cofactor is required at a higher concentration to restore normal enzyme activity.
