Carbohydrates
Monomer of polysaccharides.
What is a monosaccharide?
Defining characteristic of lipids.
What is hydrophobic or non-polar?
Organelle responsible for production of sugars in plant cells.
What is the chloroplast?
Cell wall is made of these two sugars.
What are cellulose and pectin?
Movement of particles from high to low concentrations through a membrane.
What is diffusion?
Reaction used to add a monomer to a growing polymer.
What is a dehydration reaction?
What is a phospholipid?
As cell size increases, the volume...
What is increases proportionally more?
Three structural components of membranes.
1. phospholipid bilayer
2. membrane proteins
3. cholesterol
Movement of water thru a membrane when the solute CANNOT move (or doesn't do so fast enough).
What is osmosis?
Polarity of saccharides.
What is polar or hydrophilic?
Function of cholesterol in the membrane at high temperatures.
What is increases rigidity?
5 parts of the end membrane system.
What are
-Nuclear Envelope
-Rough ER
-Smooth ER
-Golgi apparatus
-Plasma Membrane
Two influences the rigidity/flexibility of the membrane.
1. saturation of FA tails
2. cholesterol
Movement of particles from low to high concentration across the membrane requires these two things.
1. transport protein
2. energy
Polysaccharide that contains chains of glucose molecules with alternating orientation that hydrogen bond with other chains of the same to form a very rigid fiber.
What is cellulose?
Carboxyl group with hydrocarbon chain with C-C double bonds?
What is an unsaturated fatty acid?
Tetracyclines are a class of antibiotics that have recently been identified as having negative effects for eukaryotic cells. Organelle mostly likely targeted by tetracycline.
What is the mitochondrion?
Fish swims to colder water and cells alter their phospholipids to include more with ...
What are unsaturated FA tails?
Cell is placed in a hypertonic solution and the solute cannot cross the membrane. The cell will...
What is SHRINK (lose water)?
Name of the bond that hold together the monomers of sugars in a polymer.
What is a glycosidic bond (linkage)?
The function of triglycerides?
What is energy storage?
Three parts of Cell Theory.
What are...
1.All living things are composed of cells
2.Cell in the basic unit of structure and organization in organisms
3.All cells come from other cells
Function of the plasma membrane.
What is to create a barrier that allows selective movement of materials in/out?
What is facilitated diffusion?
