3. New _____ come from preexisting ____ through ____ _____

1.Living, cells

2.Cells,unit,life

3.cells,cells, cellular division

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

Draw your best fluid mosaic model

You got this Picasso :)
