We should expect that the rat will have have more difficulty in learning the task compared to a normal rat. This is because the rat has been injected with a certain drug that oppresses the dopamine activity. And then the rat is placed in an operant chamber where a lever-pressing task is shaped through positive reinforcement.

What product do all three reactions in Model 2 have in common?
belka [17]

Answer;

-They all provide water

Explanation;

In reaction A, the reactants are glucose and fructose , and the products are Sucrose and water. This is a condensation reaction, following the combination of two monosaccharides (glucose and fructose) forming a dissaccharide (sucrose) and water.

In reaction B, the reactants are two amino acids, that results to formation of a dipeptide and water; this is also a condensation reaction joining two amino acids monomers, to form a dipeptide and water.

-In reaction C, a monoglyceride combines with a fatty acid to form a diglyceride and water. This is also an example of a condensation reaction that results to formation of a diglyceride and water.

Therefore, the similarity of all the reactions is that they are all condensation reactions, with water as a common product.

Match each function with the correct enzyme class.
Savatey [412]

Answer:

The correct matching pairs are:

1) - B)

2)- E)

3) - A)

4) - F)

Explanation:

<u>Transferases (B)</u>: Transeferases is the class of enzyme that catalyzes reactions involving the <u>transfer of certain functional groups. (1)</u>

Example: Transaminase transfers nitrogenous groups

<u>Isomerases (E)</u>: Isomerases is the class of enzyme that catalyzes <u>isomerization reactions and intramolecular rearrangements. (2)</u>

Example: Triosephosphate isomerase interconverts aldoses and ketoses

<u>Oxidoreductases (A)</u>: Oxidoreductases is a class of enzyme that catalyzes <u>redox reactions (3) </u>which involves the simultaneous transfer of electron.

Example: Alcohol oxidoreductases acts on the alcohol functional group

<u>Ligases (F)</u>: Ligases is a class of enzyme that catalyzes reactions involving <u>chemical bond formation between two molecules. (4)</u>

Example: DNA ligase joins DNA fragments
