Mon/27...chromebook access to Bio webpage/ membrane proteinsTue/28... Cellular transport: Passive and active...passive requires no energy..there are 3 types of passive transport 1) Simple Diffusion... uses a concentration gradient (move from hi conc to low) if Na is highly concentrated out of the cell, it will move into the cell if a channel opens up... Particles will stop moving when there are equal parts on both sides of the membrane...called reaching EQUILIBRIUM. At which point...there is no more driving force
(FA): determine the direction of diffusion in 3 pics
Wed/29... Review passive active transport... review Simple Diffusion(FA)from yesterday 2) Facilitated Diffusion...uses a carrier protein...some things cannot enter thru the bilayer and need help...carrier proteins can change shape and bind substances to be brought into the cell. Glucose is an example./// Home work: Worksheet 64-65. Due Thur!!Thur/30...review passive transport; 1) Simple Diffusion 2) Facilitated Diffusion....Go over HW: wksht 64-65.... Go over what is a solute and a solvent...Introduce Osmosis... defined; is the movement of water through a semi-permeable membrane...water moves towards the higher concentrations of solute in order to dilute.(this is different from how particles move in simple diffusion).Fri/31... Osmosis Continued...Examples for students to see which direction water will go/ Cells in differing solute concentrations (hypertonic, hypotonic and isotonic). View Video: "Membrane transport in cells" For review and Formative assessment///see below!


Mon/3...No school!! labor dayTue/4... Review Passive Transport..ACTIVE TRANSPORT: moving substance AGAINST their concentration Gradients...Requires ENERGY in the form of also requires PUMPS that pump sub's in/out of the cell against their conc. grad.'s this is different from channels.Hand-out wksht on cell transport HW...start in class, due tomorrow!! (FA)Wed/5... go over HW... differentiate between the 2 types of active transport 1) primary active and 2) secondary active...primary uses atp-ase enzymes to make ATP over and over while secondary pumps use ATP 'till it is gone and later gets resupplied. QUIZ?

Tue/13...(FA)DRAW A Amino acid draw two and identify the peptide bond! many folds...complex and simple proteins can fold and un-fold...molecular chaperones try to fix..if not...RECYCLE!! Amino acids DENATURE = unfolded...BROKEN Hydrogen bonds! which are weak by the way Protein functions:1. Catalyst....= enzymes- speed up chem reactions2. communication: protein protein interactions...a protein can be activated or inactivated by another protein Protein channels and surface proteins3. Transportation...Hemoglobin transports oxygen4. Protection...IMMUNITY...Antibodies are proteins called Immunoglobulins

An amino Acid

An Amino Group to the left

An acid group(carboxyl group) to the right...hence, Amino Acid

Note: There are 20 different R groups...why?


Hydrogen bonds maintain protein folds!

However, hydrogen bonds can be broken by extreme heat and pH!!!

The Denaturing of a protein!!

What bonds are broken??


Two amino acids bonded together by a peptide bond makes---> A DIPEPTIDE

What do three amino acids make???

three peptides = tri-peptide

How many peptide bonds are there?
