he orange dots in this picture of the cell membrane are _________ and they are considered hydro_________.
Phosphates - Hydrophilic
200
Active or Passive: This type of transport moves from areas of higher concentration to lower concentration or down the concentration gradient.
Passive
200
T - Is diffusion the movement of particles/molecules or water?
Particles! Osmosis is the movement of water!
200

Isotonic, Hypertonic, Hypotonic
200
T - What solution is shown here and what happens to the cell? Write the whole name of the solution.
This is a hypotonic solution - The water moves into the cell, causing it to swell.
200

Solution 2
200
T - What is the formula for glucose?
(C6H1206)
200
What is the entire purpose of cellular respiration?
To make ATP (by breaking down glucose)
200
How many types of fermentation are there?
2
200
How many parts of ATP are there?
3 parts
300
T - T or F: The tails of a phospholipid are hydrophilic. You can write either "T" or "F"
False - They are fatty acids (lipids) which means they do not like water so they are hydrophobic.
300
T - What is the name of the energy that is used in active transport?
ATP - If you see a picture with ATP in it and something is moving into the cell, it is active transport!
300
If a molecule is too large to pass through the cell membrane but is still moving from high to low concentrations, what must be used to move it into the cell and what type of diffusion is this?
A protein and facilitated diffusion!
300
In a isotonic solution, what happens to the shape of the cell?
The cell shape does not change
300
T - In which type of solution would you say the first blood cell was placed in? Write the whole name of the solution.
Hypotonic - The cell burst!
300
What molecule is this?
ATP!
300
What organelle does photosynthesis happen in?
Chloroplast
300
What molecule is being broken down in cellular respiration?
glucose molecule (C6H1206)
300
T - What are the names of the different types of fermentation?
Alcoholic Fermentation and Lactic Acid Fermentation
300
T - Name the 3 parts of ATP.
Adenine, Ribose (sugar), and 3 phosphate groups
400
What is the name of the macromolecule that is imbedded in the cell membrane and helps bring over large molecules AND what color is it in this picture?
Protein - Purple!
400
T - Look at the picture: Is passive or active transport occuring?
Active - ATP is present!
400
T - Diffusion is the movement of ___________ across the cell membrane [water, molecules, air] from _______ to ________ concentrations
molecules, high, low
400
Hypotonic solutions cause a cell to ________ but hypertonic solutions cause a cell to ___________.
swell and shrink/shrivel up
400
What type of solution is this and what happens to the cell? Write the whole name of the solution.
Hypertonic - The cell shrinks!
400
T - What would happen to your cells and why?
This would cause your cells the shrivel up as all the water would move to the IV fluid that has a high amount of salt (a low amount of water). Your cells would have a higher amount of water and since water moves from high to low, your cells would shrink/dehydrate.
