Answer:

B) Transferases ⇒ 1) transfer functional groups between molecules

E) isomerases ⇒ 2) catalyze intramolecular rearrangements

A) oxidoreductases ⇒3) catalyze redox chemistry

F) ligases ⇒4) catalyze the joining of two molecules together

Explanation:

The question deals with enzyme classes.

There are 6 enzyme classes.

  1. Transferases
  2. Lyases
  3. Ligases (Synthetases)
  4. Oxidoreductases
  5. Hydrolases
  6. Isomerases

1. TRANSFERASES:

They are responsible for catalyzing the transfer of functional groups from one molecule to another. The molecule from which the functional group is transferred is called Donor and the molecule to which the functional group is transferred is called Acceptor.

e.g. Hexokinase enzyme which catalyzes the transfer of phosphate group from ATP to glucose.

2. LYASES:

They are responsible for breaking down covalent bonds without oxidation and hydrolysis.

e.g. Histdine decarboxylase enzyme which breaks covalent bonds in Histidine molecule.

3. LIGASES (SYNTHETASES)

They are responsible for joining molecules (ligation).

e.g. DNA polymerase which links subunits in DNA.

4. OXIDOREDUCTASES:

They are responsible for oxidation and reduction reactions and act by removing or adding electrons or Hydrogen ions.

e.g. Cytochrome oxidase

5. HYDROLASES

They break down bonds with the help of water molecule.

e.g. proteolytic enzymes which break bonds in proteins with the aid of water.

6. ISOMERASES:

They bring intramolecular rearrangements in molecules. Such intramolecular rearrangements lead to the formation of isomers. Isomers are molecules with the same chemical formula but different arrangement of atoms.

e.g. Phosphohexose isomerase converts glucose 6-phosphate into fructose 6-phosphate.

How do strong southerly winds affect the vapor pressure?
dedylja [7]

Answer:

An increase

Explanation:

The strong southerly winds affect the vapor pressure by increasing it .

When the vapor pressure increases it means an increase in temperature and more evaporation occurs.

A decrease in the vapor pressure means a reduction in temperature with less amount of evaporation being involved

Please help quick the 6th question is “What is a catalyst?” (include all three parts)
allochka39001 [22]
1. The reaction is exothermic.

2. I know this because the delta H is a negative number. (-802.4 kJ)

3. This means that this reaction releases heat.
