100
Give the definition of these two terms:
Polymers:
Monomers:
Polymers: chain of monomers
Monomers: smaller components of polymers
100
What is the main difference between passive and active transport?
Active requires energy
100
What is the definiton of these two terms:
Multicellular:
Unicellular:
More than one cell
One cell
200
The left side of a chemical reactions is known as?
Reactants
200
Name the function of these organelles:
Flagella:
Glycocalyx:
Pilli:
Flagella: movement
Glycocalyx: water regulation prevents drying out
Pilli: attachment
200
What is the main difference between a unsaturated and saturated fatty acid?
Extra 100 points if you can give an example of each
Unsaturated: double C C bond
Saturated: single CC bonds
200
What are the two main types of transport of substances in our body. Give an example for each.
Active and Passive
passive: simple, facilitated, osmosis
Actie: primary and secondary
200
What are the two ways a phospholipid can move?
Rotating or change location with another phospholipid
300
Balance this equation:
C6H12O6 + O2 -> CO2 + 6H2O
C6H12O6 + 6O2 -> 6CO2 + 6H2O
300
Calculate the volume of a 1 by 1 cube
1 unit^3
Bonus 200 if they get the unit right
300
Name the 4 macromolecules and at least one function for each
Proteins: enzymes
Carbs: energy storage
Nucleic acids: stores genetic info
Lipids: hormones
300
List at least 3 factors that can be used to increase the permeability of a membrane. For extra context you are in an environment with freezing temperatures.
You can increase the number of unsaturated fatty acids, shorten the length of the tail and increase cholesterol imbedded in the membrane
300
What type of reaction allows us to create a triglyceride?
Bonus 200 points if you can list the reactants needed to make a triglyceride.
Dehydration
3 fatty acids and a glycerol molecule
400
What is the difference between and ionic bond and a covalent bond.
Extra 200 points if you can give an example of an ionic bond
Ionic bond one molecule takes all the electrons
Covalent bond they share then equally
400
Name the membrane bound organelles with two membranes that surround them
Extra 200 if you can explain why this occurred
Mitochondria, Chloroplasts, and nucleus
Extra: through the endosymbiotic theory
400
What makes phospholipids the perfect molecule to form out membranes?
They are amphipathic which allows them to regulate what goes into the cell very effieciently
400
A glucose molecule is a very large molecule that requires a certain process to pass through the membrane. Outline the type of diffusion happening as well as the certain protein required to make this happen.
It is facilitated diffusion an requires a transporter protein
400
What direction will the polarity go towards in a molecule of H2O?
It will be pulled in the direction of the Oxygen molecule.
500
Determine which of these will dissolve in water:
N2
and
F-H
F-H because it is polar
500
Outline the full pathway a protein takes from creation to the outside of the cell including all organelles, transportation it takes, and actions performed at each organelle. (in an animal cell)
It starts in the ribosome on the rough ER then a piece of the rough er is pinched off to form a vesicle that is sued to transport it to the Golgi apparatus, from there it is sorted and packaged to be sent out through another vesicle to the plasma membrane of the cell
500
Outline the steps of a dehydration and hydrolysis reaction. Include all products and any molecules that are used in the reaction.
You know this
500
You have a cell placed in a solution that is 20% water to 80% solute. The cell itself contains 85% water to 15% solute. Which way will the water flow and create a sentence to describe this process.
DOUBLE JEOPARDY
The external environment is hypertonic to the internal environment of the cell. The water will flow out of the cell.
500
