Marfan syndrome is an autosomal dominant disorder caused by a mutation of the FBN1 gene that affects the connective tissue of the body. Suppose that two parents, a father with genotype FBN1 fbn1 and a mother with genotype FBN1 fbn1, are planning to have a family. What is the probability that they will have an affected son as their first child

a time line cause it goes from 685 to 978

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.
