Enzymes

Question 1

Catabolic pathway

Answer 1

breaks down polymers/molecules (releases energy as ATP)

Question 2

Anabolic pathways

Answer 2

Synthesize molecules and polymers from smaller starter materials (requires ATP)

Question 3

explain how G values change based on whether a reaction is spontaneous or not.

Answer 3

when G is a negative value the process is spotaneous and when G is a positive value the reaction requires energy and is therefore non-spontaneous.

Question 4

What does an enzyme do to a reaction?

Answer 4

an enzyme works to lower the activation energy of a reaction, they work as catalysts and are not consumed during reaction, and they are highly specific

Question 5

explain induced fit hypothesis.

Answer 5

refers to the fact that the active site shape shifts slightly after the substrate is in the active site

Question 6

enzyme function is specific to…

Answer 6

pH and temperature

Question 7

What is a co-factor?

Answer 7

is non-protein molecules that can either be organic (coenzymes aka vitamins) or non-organic (zinc. iron or copper) and functions to ensure enzyme function

Question 8

explain the difference between a chemical inhibitor and a non-competitive inhibitor.

Answer 8

A competitive inhibitor binds to the active site making it unavailable, and a non-competitive inhibitor binds to a different site on the enzyme causing a shift in the active site so it is no longer able to attract a substrate.
