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).

True or False. When reactions are too slow to meet the needs of the cell, enzymes are missing from cells and cellular reactions.
EleoNora [17]

Answer:

True

Explanation:

Organic catalyst that increase the rate of biochemical reactions in the cells of living organism s are called enzymes.The are proteins with active sites which are specific to a particular  substrate, for enzyme-substrate complex and later enzyme product complex to formed.

They  act by lowering the activation energy  in the organic chemical reaction therefore increase the rate at which chemical reactions progress.

Hence when  the reactions are too slow,activation energy are high,because enzymes are not available to catalyze the reaction fixing the active sites with the the substrates.
