Types Of Metabolism

Question 1

What is primary metabolism?

Answer 1

Occurs during active growth (lag and log)

Microbe breaks down substrate to make energy

Primary metabolite such as amino acid’s produces

Question 2

What is secondary metabolism?

Answer 2

Occurs at the end of the log phase and during the stationary phase

Secondary metabolites are remade

Question 3

What are primary metabolites used for?

Answer 3

Growth

Question 4

What are secondary metabolites used for?

Answer 4

Offer some kind of advantage

Question 5

What does a precursor do?

Answer 5

Early metabolite in the pathway

Question 6

What does an inducer/regulator do?

Answer 6

When an inducer of an enzyme is added, more of the enzymes are available to convert to the required metabolite

(provided a supply of the previous metabolite is present)

Question 7

What does an inhibitor/repressor do?

Answer 7

An inhibitor of the next enzyme in the pathway (after the required metabolite)
