Match the terms with the correct definitions. 1. a nonprotein molecule or ion that is needed for an enzyme to carry out catalysis 2. an enzyme unable to act as a catalyst because its cofactor is removed 3. an organic molecule, such as a vitamin, needed by an enzyme to carry out catalysisa. coenzymeb. cofactorc. apoenzyme

1- a(cofactor)

2.-c(apoenzyme)

3-b(coenzyme)

Explanation:

Cofactor are non -protein molecules that catalyzes reaction,they increase the rate of chemical reaction. They can be organic or inorganic.

Coenzyme can be derived from vitamins,organic molecules, they facilitate chemical reaction and can be bounded strongly to protein while others are bounded loosely to protein.

Apoenzyme are inactive enzymes that cannot catalyze reaction they lacks cofactor.

you are certainly talking about this picture:

a: is the label of the white square, it is showing the  replication fork, formed by helicase (d) ==> so it is the site of dna separation and replication 

b: is a new dna brand that is following directly the replication fork, so it is continuous ==> built continuously from 5' to 3

c: dna polymerase cannot replicate dna on its own, it needs the of their proteins, and one of them plays the role of a clamp which fixes  the dna with the dna template and increases  the processivity of the enzyme. ==>   stops polymerase from falling off the  template.

d: is the enzyme responsible for forming the replication fork (helicase) ==> unwinds and separates dna into two strands

e: is the delayed strand, it is built  in the opposite sense of the helicase, so dna will be built in fragments ==> built  fragments from 5' to 3 joins

and finally f: is the enzyme that builds  the new dna strand (dna polymerase) ==>   adds nucleotides to make a new dna helix.

sorry, is there a picture? i do not see any arrows.
