Enzyme - The need for speed!

Learning Targets...

1. I can name the form and function of enzymes.
2. I can compare/contrast anabolic and catabolic reactions.
3. I can compare / contrast inhibition methods.
4. I can explain how denaturing an enzyme is dangerous and irreversible.
5. I can define key 'enzyme' terminology.

Multiple Choice

Which substrate will be broken down by the blue enzyme?

• A

• B

• C

• E

• D

None of these substrates fits into the active site.

ENZYMES HAVE SPECIFICITY!

Multiple Choice

The graphic is showing an example of a ______ catalyzed reaction. (click the image to enlarge)

• Anabolic

• Catabolic

Remember...Catabolic is to 'breakdown'. This shows a single substrate coming in and two products leaving.

ANABOLIC = Build!

Multiple Choice

The graphic is showing an example of a ______ catalyzed reaction. (click the image to enlarge)

• Anabolic

• Catabolic

Multiple Choice

The graphic is showing an example of a ______ catalyzed reaction. (click the image to enlarge)

• Anabolic

• Catabolic

Multiple Choice

The graphic is showing an example of a ______ catalyzed reaction. (click the image to enlarge)

• Anabolic

• Catabolic

Multiple Select

Which of these names of ENZYMES?

• Lipase

• Sucrase

• Sucrose

• Glucose

• Amylase

The name of most enzymes will end with the suffix '-ase'. Some end with '-sin'.

Sugars end with the suffix: '-ose'

Multiple Choice

Which enzyme will likely breakdown 'lactose', the sugar in milk?

• Lactase

• Lactin

• Lactamine

• Lackert

Multiple Choice

Which of these images represents a product that undergoes an EXOTHERMIC reaction.

EXOTHERMIC means 'release heat'

ENDOTHERMIC = absorbing heat = products colder.

Multiple Choice

Which conclusion seems most fitting for this image?

• Enzymes will DECREASE the activation energy of a chemical reaction.

• Enzymes will INCREASE the activation energy of a chemical reaction.

Multiple Choice

The graphic is most likely showing which biochemical process?

• Glycolysis

• ATP Synthase

• Photosynthesis

• Electron Transport Chain

Notice Sugar is the reactant, Pyruvate the product...

Remember Cellular Respiration and the STEM Case?

Multiple Choice

Which line represents the 'catalyzed' reaction?

• Blue Line

• Red Line

Multiple Choice

This reaction would...

• Produce heat (get hotter)

• Absorb heat (get colder)

• No way of predicting.

Multiple Choice

This reaction would...

• Produce heat (get hotter)

• Absorb heat (get colder)

• No way of predicting.

The product (Sugar) has more energy than the reactants (energy needed to be absorbed).

This would cause the reaction to be 'colder' - ENDOTHERMIC.

Open Ended

What chemical reaction is being shown in the energy diagram? What evidence makes you believe you are correct?

This is showing - PHOTOSYNTHESIS

Carbon Dioxide and Water are inputs - Sugar is the output! By the way...the energy to make this occur...THE SUN!

Multiple Choice

Which graphic is demonstrating COMPETITIVE INHIBITION?

• Enzyme A

• Enzyme B

Enzyme A shows the inhibitor (Yellow) is taking the active site so the red substrate can't bind to the active site.

Multiple Choice

This graphic demonstrating that a 'non-competitive' inhibitor will _____ the shape of the active site. Pick the best answer.

• Change

• Enlarge

• Shrink

• Block the site

Multiple Select

Which of these are related to 'enzymes'? (Mr. Ackert talked about these).

• Milk Allergies

• Digestion of Food

• Antibiotics weakening bacteria

• Stem Cell Use in humans

• Chromosomal Mutations

Multiple Choice

Which term below best explains why the enzyme on the right won't work anymore?

• Denatured

• Allosteric Inhibition

• Mutation

• Inactivation

• None of these are a term that explains the change in shape.
