Many of the biochemical reactions that occur within cells are catalyzed by enzymes. Which of the following statements is true about most enzyme-assisted reactions? >Most enzyme-assisted reactions are slow.> Most enzyme-assisted reactions can take place at any temperature. >Most enzyme-assisted reactions can take place only within a ribosome. >Most enzyme-assisted reactions are reversible.

MOST ENZYME ASSISTED REACTIONS ARE REVERSIBLE.

this is because :

1. most enzyme assisted reactions are fast , not slow.

2. most enzyme reactions cannot take place at any temperatures as enzymes get denatured at high temperatures and so are will become unable to work.

3. ribosomes are organelle in cytoplasm which form proteins for cells.....as enzymes are proteins we can say they also manufacture enzymes.......but it is not necessary that enzyme assisted reactions can only take place within a ribosome.

4. but it is known that MOST enzyme assisted reactions ARE reversible.

so option 4 is true.

HOPE IT HELPED !!!!
