B. By increasing the activation energy of the reaction
C. By decreasing the activation energy of the reaction
D. By increasing the energy of the products of the reaction
E. By decreasing the energy of the products of the reaction
Answer:
Enzymes help to carry out biochemical reactions C). By decreasing the activation energy of the reaction
Explanation:
Enzyme catalysis An enzyme catalyzes a biochemical reaction by binding a substrate at the active site. After the reaction has proceeded, the products are released and the enzyme can catalyze further reactions.
DNA in the nucleus of eukaryotic cells is collected into a chromatin.
A chromatin is a complex of nucleic acids (DNA or RNA) and proteins called histones which condense to form a chromosome during cell division.
In eukaryotic cells, it is found within the cell nucleus while in prokaryotes, it is found inside the nucleoid .
Its functions are;
1. to package DNA into a smaller volume to fit in the cell.
2. strengthen the DNA to allow mitosis and meiosis.
3. acts as a mechanism to control expression
The chromatin is easily recognized through staining. Its name literally means "colored material."
