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 cellsas enzymes are proteins we can say they also manufacture enzymesbut 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  

the level of progesterone is low at the pre-ovulatory phase of the cycle but it gradually increases and the levels are high at the luteal phase. if pregnancy occurs, the level of progesterone will be high throughout the pregnancy.

if egg is fertilized and the mother gets pregnant, progesterone starts preparing the uterus for the implantation. it starts building up the lining of uterus and make it hostile of the period of pregnancy.

c) 50% there are four chromosomes. after crossing over, 2 of the four have been changed. that means any gamete has a 2 in 4 chance or 50% chance of receiving the mutated chromosome.
