Biomolecules Notes

Your teacher will review the  lecture on biomolecules here:  Please review the notes on Carbohydrates and Proteins

Biomolecules Notes 

Scenarios

 1.  An athlete forgot their water bottle when going to soccer practice.  After a while, the athlete notices that their pee is bright yellow, they are feeling light headed and dizzy.  What can they do to fix their situation and explain how their situation can be fixed by paying attention to OSMOSIS, DIFFUSION, ELECTROLYTES,  

2.  A 2 year old child is constantly getting respiratory infections, bronchitis, and lots of phlegm. They have symptoms of shortness of breath.  They say" my skin tastes REALLY SALTY!!!" What might be troubling this child.  Hint: it has something to do with carrier proteins on a cell membrane and the central dogma.  

3.   An adult wears contact lenses and decides to use distilled water instead of saline solution for cleaning their lenses.  They find that this causes great discomfort.  What might be causing their discomfort. Explain using the terms hypertonic, hypotonic, isotonic. 

Please answer these questions with a partner.  If you DRAW A PICTURE, then it communicates your answer even more effectively!  Answer in one  or two pages. Hand in before the period ends 

Pandemic architecture to respond to infectious respiratory diseases

We will be meeting at 9:30 at the box office of the Vancouver Orpheum Theatre on March 2 for attendance to listen to a performance of Beethoven and Prokofiev.  During the performance we will take data including estimating capacity, calculating ventilation and observing design features which support displacement ventilation.

Happy Valentines Day!

 On this valentine's day, give YOURSELF a valentine by taking care of your heart!  

Notes on The Cell

 On the first day of class we looked at the criteria of living things and we began to go over the Cell Structures   You will get an online quiz on wherever we get to by Thursday

THERE ARE TWO TYPES OF TRANSPORT IN A CELL

ACTIVE TRANSPORT 

    -anything that requires ATP is active transport 

    -endocytosis, which includes :

    1. Phagocytosis - a cell engulfs a smaller item using pseudopods

    2. pinocytosis

    3. receptor mediated endocytosis

Any movement of molecules AGAINST THE CONCENTRATION GRADIENT is 

active transport.  Carrier proteins are often used for Na+,  Cl+ 

           

PASSIVE TRANSPORT

    moves molecules across the plasma membrane (aka the cell membrane) ALONG

    the concentration gradient. 

    EXAMPLES:

    SIMPLE DIFFUSION - small nonpolar molecules, including O2 and CO2

    FACILITATED DIFFUSION - LARGER molecules like glucose, starch, water

     facilitated diffusion uses channel proteins , can sometimes use carrier proteins 

    

OSMOSIS 

the diffusion of water 

When an animal cell is in a hypotonic solution, it fills with water and bursts (lysis). 

A plant cell is prevented from bursting by the cell wall. A plant cell merely experiences

TURGOR PRESSURE 

Respiratory System

The picture link below shows a journey through the respiratory system

Notes are here and please get the DIAGRAM NOTES from me. Plus detailed notes here

Control of respiration

CO2 and H+ Levels

As monitored by the carotid and aortic bodies.  If these levels increase, they send a message to the  medulla oblongata Carotid bodies send the message through VAGUS NERVE.  Aortic bodies send the message through the GLOSSOPHARYNGEAL NERVE.  Medulla oblongata stimulates the rib cage and the diaphragm to move faster.

Acidosis:  pH < 7.35         too much carbon dioxide

Alkadosis: pHB> 7.45       not enough carbon dioxide (sometimes caused by hyperventilation)

The normal blood pH is tightly regulated between 7.35 and 7.45.

Carbon monoxide:   hemoglobin has a higher affinity for CO than for O₂ how would CO affect internal and external respiration?

What's on the test?

ON THE DAY OF THE TEST, HAND IN:
You must make a BIG ILLUSTRATED SUMMARY OF THE TOPICS WE COVERED.  THIS WILL BE OUT OF 10 MARKS.  IT MUST BE IN INK, IN COLOUR, AND INCLUDE ALL MAJOR VOCAB.

There will be a multiple choice test this friday May 3  based on the following.  Note that Fetal circulation will be excluded since it was not mentioned in class.

1.  your heart dissection.
2.  These notes which I gave out.
 the slideshowCirculation System
path of blood notes
  Major Blood Vessels
Do the review on blood vessels .
 and work on this guided study based on these summary notes

3.  Your notes on ECG:  these  fill in notes

And their answer key to look at

review your gigantic DIAGRAM on circulation

and we will explore the  path of blood . In particular, we will replicate William Harvey's experiment
