  • Monday, September 9, 2013 ( 5th & 7th )

    What type of macromolecules is an enzyme?


Enzymes

Enzymes

A type of Protein


Objectives
Objectives

1. Identify the role of enzymes

2. Describe the components of an energy hill diagram


Role of enzymes
Role of Enzymes

  • Characteristics

    1) are proteins

    2) Are catalyst

    3) End in –ASE (Ex: Amylase in saliva)

  • Catalyst = speeds up the rate of a

    chemical reaction


Active site
Active Site

  • Substrate= material on which enzyme acts

  • Active Site = site of chemical reaction between (btw) substrate & enzyme


Lock and key
Lock and Key

  • Enzymes & substrates  Lock & Key relationship

  • Enzymes will fit a SPECIFIC substrate


Activation energy
Activation Energy

  • Activation Energy = energy needed to get a reaction started



Label reaction w an enzyme
Label: Reaction w/ an enzyme

Enzyme

(does NOT

change)

Substrate

Products

Active

Site

Lock & Key Fit


Enzymes as robots
Enzymes as robots

  • Enzymes perform the SAME reaction over and over again

  • The enzyme is NEVER altered! Only the substrate.


Inhibitors
Inhibitors

  • Inhibitor = molecule that binds to enzymes & decreases their activity

  • Competitive Inhibitor = binds to active site of enzyme & prevents substrate binding

  • Ex. Chemotherapy


Enzymes in your body
Enzymes in your body

  • Enzymes found in saliva:

  • Amylase- help break down carbs

  • Protease- help break down protein

    3. Lipase - help break down fats


Enzymes in products
Enzymes in products

  • Laundry Detergent- (Tide, Arm & Hammer, Oxy Clean) contains protease, amaylase and mannanase

  • Frizz Ease- contains dismutase; converts superoxide and protons.


Reminder summary
REMINDER: Summary

  • Draw horizontal line at end of notes

  • Write “Summary”

  • Write 3-5 sentences about specific things you learned about enzymes

  • Use COMPLETE sentences


Create an enzyme
Create an Enzyme

  • Create an enzyme that would help you in your life. (Example: helps you finish a chore in 1 minute)

  • Name the enzyme (remember end in –ASE)

  • Draw a picture of the enzyme. Use at least 3 colors.

  • Write 2 complete sentences explaining how the enzyme will help you out.

    ***Worth 4 stamps…remember you can earn a 5th stamp for extra credit if you create a WOW assignment***


Enzyme reading assessment
Enzyme Reading Assessment

Instructions:

***Do NOT write on the handout***

1. The provided reading is divided into 4 sections. Read each one.

2. Summarize each section using a 7-9 word complete

sentence. (you should have 4 short summaries)

3. After you complete the 4 sections, summarize the

entire passage using 13-15 words. (5 summaries total)

**THIS DOES NOT TAKE ANY TALKING**
