In order to survive, all organisms must carry out 1) autotrophic nutrition 2) heterotrophic nutrition 3) enzyme-controlled reactions 4) the process of reproduction

Correct Answer is (3)

Explanation:

    (3) In order to survive, all organisms must carry out enzyme-controlled reactions.

Enzymes is the Most of the responses that happen in living life forms are chemical controlled. They are along these lines explicit in the responses that they catalyze  one chemical will respond with particles of one substrate. The site of the response happens in a territory on the outside of the protein called the active site. Enzymes can be influenced by an assortment of elements, for example, temperature, pH, and focus. Chemicals work best inside explicit temperature and pH ranges, and imperfect conditions can make a protein lose its capacity to tie to a substrate.The most of the enzyme has an optimum pH range.
