They include the temperature and the pH value.
Each enzyme has a temperature range and pH range that makes them has the quickest action, they're called the optimum temperature and pH. Each optimum temperature and pH is different for each enzymes.
For example, the enzyme in our stomach has a optimum temperature of human temperature range, and a optimum pH for 2.0
However, if the temperature is too low or the pH value is too extreme, the enzyme may denature. The enzyme can no longer work to digests any substrate.
Answer:
Chromatin helps regulate DNA replication.
Explanation:
Chromatin helps condense DNA strands to smaller units that can be easily managed during DNA replication and gene expression. This also prevents the breakage of the strands and facilitates equal distribution of chromosomes during cell division (during mitosis and meiosis).
Answer:
It prevents harmful substances from entering a cell.
Explanation:
Answer: d. Extracellular matrix was discovered more than 20 years ago.
Explanation:
According to biological sciences, the extracellular matrix is a matrix that consists of three dimensional network of extracellular macromolecules such as enzymes, collagen and glycoproteins which provide structural and biological support for surrounding cells as well.
It is found that it is discovered over 20 years ago in the matrix formed in the mouse EHS sarcoma. Therefore, correct answer is (d).
