What will the "AFTER" picture look like using this image as the "BEFORE" image?

There will be no change - it will look the same.

All the O2 will move out of the red blood cell and into the muscle cells AND all the CO2 will move out of the muscle cells and into the red blood cell

There will be more O2 in the in the muscle tissue and more CO2 in the red blood cell than there is in the image above.

There will be an equal amount of O2 and CO2 in both the red blood cell and the muscle cells

Select all the statements that are correct based on the image and what you learned in class

All molecules with charges or ions (charged atoms) will diffuse across a cell membrane on their own (with no help)

All molecules with charges or ions will diffuse across a cell membrane if there is any open channel or carrier molecule in the cell membrane. Any charged molecule or ion can diffuse through any channel or carrier molecule in the cell membrane. For example, a water molecule could go through an aquaporin, an ion channel or a GLUT.

All molecules with charges or ions can only diffuse across a cell membrane in a process called facilitated diffusion

All molecules with charges or ions will diffuse across a cell membrane if there is a channel or carrier protein in the cell membrane that is specific to that exact molecule. Each charged molecule or ion requires its own specific protein to facilitate its diffusion.

Referring to the image, select all statements that are true ....

The concentration gradient of the glucose is from outside the cell to inside the cell

The glucose molecules are able to move directly across the phospholipid bilayer

This images shows an example of facilitated diffusion.

Gluts are carbohydrates that facilitate the movement of glucoses across the cell membrane

This image shows what body cells, especially muscle and fat cells, should do (increase the number of GLUTS in their cell membranes) in response to a rise in blood sugar

What type of transport is taking place in the image below (2 word answer)?

null

Select all statements that correctly describe what is happening in the image

there are more H+ ions (protons) OUTSIDE the cell than inside the cell

this is passive transport

pumping the H+ protons OUT of the cell (the way the red arrow is pointing) would require ATP to energize the proton pump

this is an example of facilitated diffusion

What kind of transport is depicted in the image? Name at least one reason how you know it is that kind of transport.

A sailor stranded at sea in a small life boat runs out of fresh water and must drink sea water (human cells are about .9% solute and therefore 99.1% water AND ocean water is about 3.5% salt (solute) and therefore about 96.5% water). Which of the 3 choices below would be what would happen to the sailor's red blood cells as the salt water is absorbed? Then explain WHY your choice is correct!

Marathon runners are at risk for hyponatremia or water intoxication when they drink large amounts of water during the race. This extra water floods the blood and the fluids around their cells so there is more water OUTSIDE than INSIDE their cells. Explain what happens next using the word osmosis and explain why the BRAIN is the organ that is most affected by the movement of this extra water.
