Imagine a small syntyetic vesicle made from pure phospholipids enclosing an interior lumen containing 1 mM glucose and 1mM sodium chloride. If the vesicle is placed in pure water what will happen first?
A. Na+ diffuses out.
B. cl- diffuses out.
C. H2O diffuses in.
D. Glucose diffuses out.
E. NaCl diffuses out.

The preferable statement will be - C.

C. H₂O diffuses in.

Explanation:

it provides an alternative energy pathway for the reaction to proceed.

a catalyst is a substance that speeds up the rate of a chemical reaction but is not consumed during the course of the reaction.

catalysts increase the rate of reaction without being used up. they do this by lowering the activation energy needed. with a catalyst, more collisions result in a reaction, so the rate of reaction increases. different reactions need different catalysts.

a catalyst works by providing an alternative reaction pathway to the reaction product. the rate of the reaction is increased as this alternative route has a lower activation energy than the reaction route not mediated by the catalyst.

all these collisions do one thing, and that thing is explained in the last option. when dusst, rocks and ice collide, they harden and form giant layers of rocks or hard ice.

d)   to harden materials to form different parts of earth’s layers
