Enzyme/Catalyst

a protein that makes chemical reactions go faster

100

Enzymes are reusable (Yes or no)

Yes

100
Enzymes are specific to one type of _____________ because...
What is substrate. Due to shape
100
thyroxin
What is a protein hormone which is secreted into the blood by the thyroid gland and causes an increase in cell metabolic rate
200

Synthesis

to build or put together

200

Enzymes are different shapes? (Yes or no)

Yes

200

The theory stating that the enzyme and it's substrate are perfectly shaped to fit each other.

What is Lock and Key theory

200
3 ways a cell regulates enzymes once they are already produced
What is 1. competitive inhibition 2. non-competitive inhibition 3. feedback inhibition
200
the storage form of thyroxin which requires iodine for production.
What is thyroglobulin
300

Optimum

Best

300

Enzymes are "Specific" What does than mean?

Each enzyme has  different shape for each job it does.

300

3 ways that enzymes can be involved in reactions

What is 1. bring substrates together 2. Help break apart substrates 3. Participate in the reaction.

300
a molecule moves binds to the active site of an enzyme and causes the enzyme to stop catalyzing reaction
What is competitive inhibitor
300
Hypothyroidism
What is lack of iodine in the diet leading to simple goiter in which the thyroid gland enlarges to try to meet the metabolic demands of the body.
400

pH

measurement of acids or bases

400

Enzymes can be destroyed by _____ or _____

What is temperature and pH

400
Induced Fit theory
What is the enzyme and substrate complex causing a change in shape. the enzyme returns to normal after the product leaves
400
How non-competitive inhibitors stop enzyme action
What is inhibitor molecule such as heavy metal binds to alosteric site (not active site) and changes shape of enzyme so it is unable to bind substrate.
400
Exophthalmic Goiter
What is Hyperthyroidism (graves' disease) in which excess thyroxin is produced. also features an enlarged thyroid gland, protruding eyeballs, tachycardia, and nervous excitability.
500

Reaction Rate

how fast or slow enzymes work

500

How do enzymes work?

Molecule has to fit into the enzyme for it to work

500

Denatured

The enzyme shape is changed due to breaking of the hydrogen bonds

500
How feedback inhibition stops an enzyme and starts it again.
When the product of a metabolic pathway acts as an inhibitor for one of the enzymes in the pathway. As the concentration of product increases more enzymes are inhibited and product formation slows and stops. As the concentration of product decreases product is released from the inhibited enzyme and the pathway starts up again creating more product.
