EcoRegion Project Presentations

Part of your grade will be based on your presentation and your attention during your classmates’ presentations.

Hand me your rubric when you come up to present.

Ecology Peer EvaluationsOn the top left of your paper please PRINT all group members names (first & last)

On the top right of your paper please PRINT your name

Divide your paper into three sections (one section for each of your partners and one section for your self evaluation). Write your partner's names above one of the sections and your name above the last section)

Answer these questions using COMPLETE SENTENCES about each partner in their section of your paper and about yourself in your section.

1. Did your partner complete their assigned section of your presentation?2. Did your partner complete their assigned section on time?3. Did your partner use their class time wisely?4. Do you think your partner adequately explained their section? Why or why not?5. Did your partner include video clips and diagrams or any additional material for their section?6. What grade do you think your partner deserves AND WHY?

**DO NOT let anyone see your evaluation. Bring your paper to me.

Evolution = Change over TimeLizard Activity

Relay race

1st person on the team comes up and draws the lizard as fast as they can. They flip the original lizard over and leave theirs face up.

2nd person comes up once first person sits down and draws their lizard based on the first person’s drawing .

2nd person flips first person’s lizard down and flips theirs up.

3rd person comes up once second person sits down and they draw their lizard based on the second person’s drawing as fast at they can. They flip the second person’s lizard over and they leave their lizard face up.

PPTProteins???

Proteins

Proteins Most structurally & functionally diverse

group of biomoleculesFunctions:

involved in almost everything enzymes structure (keratin, collagen)carriers & transport (membrane channels)receptors & binding (defense) contraction (actin & myosin)signaling (hormones)storage (bean seed proteins)

ProteinsStructure:

monomer = amino acids20 different amino acids

polymer = polypeptideprotein can be 1 or more polypeptide chains

folded & bonded together

large & complex molecules

complex 3-D shape

Amino acids Structure:

central carbon amino groupcarboxyl group (acid)R group (side chain)

variable group confers unique

chemical properties of the amino acid —N—

H

H

H|

—C—|

C—OH

||O

R

Nonpolar amino acids nonpolar & hydrophobic

Polar amino acids polar or charged & hydrophilic

Sulfur containing amino acidsDisulfide bridges

cysteines form cross links

Building proteinsPeptide bonds: dehydration synthesis

linking NH2 of 1 amino acid to COOH of another

C–N bond

peptidebond

Building proteinsPolypeptide chains

N-terminal = NH2 end

C-terminal = COOH end

repeated sequence (N-C-C) is the polypeptide backbone

grow in one direction

Protein structure & function

hemoglobin

function depends on structure3-D structure

twisted, folded, coiled into unique shape

collagen

pepsin

Protein structure & functionfunction depends on structure

all starts with the order of amino acidswhat determines that order of

amino acids?

lysozyme: enzyme in tears & mucus that kills bacteria

the 10 glycolytic enzymes used to breakdown glucose

to make ATP

Primary (1°) structureOrder of amino acids in chain

amino acid sequence determined by DNA

slight change in amino acid sequence can affect protein’s structure & it’s functioneven just one amino acid change can

make all the difference!

Primary (1°) structure: Sickle cell anemia

Secondary (2°) structure“Local folding”

folding along short sections of polypeptideinteraction between

adjacent amino acids

H bonds onbackbone

-helix

-pleated sheet

Tertiary (3°) structure“Global (whole molecule)

folding”determined by interactions

between R groupsanchored by

disulfide bridges

stabilized by hydrogen and ionic ‘bonds’

hydrophobic interactions

effect of water in cell

2°

3°

Quaternary (4°) structureJoins together more than 1 polypeptide chain

only then is it a functional protein

Chaperonin proteins Guide protein folding

provide shelter for folding polypeptides

keep the new protein segregated from cytoplasmic influences

Protein modelsProtein structure visualized by

X-ray crystallography

extrapolating from amino acid sequence

computer modelling

lysozyme

Protein structure (review)R groups

hydrophobic interactions, disulfide bridges, ionic bonds

R groups hydrophobic interactions,

disulfide bridges, ionic bonds

4°

1°

2°

3°

Denature a proteinDisrupt 3° structure

pH

temperature

salt

unravel or denature protein

disrupts H bonds, ionic bonds & disulfide bridges

Some proteins can return to their functional shape after denaturation, many cannot!

Think eggs… Once you cook ‘em, there is no going back!

Love them Proteins!
