Living vs. Non-Living/Viruses
If yes, describe this process. If no, explain what they must have.
Describe the difference in prokaryotic and eukaryotic cells.
Prokaryotic - simple, no membrane bound organelles, no nucleus, does have a cell membrane, unicellular
Eukaryotic - more complex, does have membrane bound organelles, has a cell membrane, unicellular or multicellular
An enzyme is a catalyst, what is a catalyst? What does a catalyst do? How does it do that?
A catalyst is an enzyme that speeds up a chemical reaction by lowering activation energy.
Which of the following compounds is most likely to be a part of living organisms?
MoCl2
BF3
C6H12O6
CsI
What are the three parts of the cell theory?
- All cells come from pre-existing cells
- All living things are made of cells
- Cells are the basic unit of life
1. If you come in contact with someone who has the flu and you begin to feel sick in a few days, what viral replication process has taken place?
2. Can you take antibiotics to feel better? Why or why not?
1. Lytic Cycle
2. No, antibiotics can only be used to fight "live" infections. A virus is not living.
Which organelle helps to detoxify and creates hormones/lipids?
Smooth ER
List at least two things that can cause an enzyme to no longer work
Increase in temperature or increase/decrease in pH
What do the following suffixes represent?
-ose
-in
-ase
-ose = carbohydrates
-in = proteins
-ase = enzyme
Draw and label a phospholipid bilayer.
Use these words: Head, Tail, Hydrophobic, Hydrophilic
Hold up your picture :)
Explain the difference in the lytic and lysogenic replication cycle.
Give details.
Lytic cycle is quick - contact with a virus will result in you being sick soon.
Lysogenic cycle is longer - the virus can hide in DNA and be replicated without you becoming sick (dormant). You can become sick if a trigger occurs.
What do the ribosomes on the rough ER help to do/make?
Draw and label an enzyme-substrate complex (looking for four main descriptive words)
Picture + labeled (enzyme, substrate, active site, product)
Which macromolecule contains CHONP?
What is the monomer of that macromolecule?
Nucleic Acid
Nucleotide
What is the tail like structure of some unicellular organisms called? It helps them to be motile.
Flagella
How does a vaccine help to "fight" a virus? What is a vaccine?
A vaccine is a weakened or dead version of the virus injected. The immune system creates antibodies that can fight the infection.
List 3 major differences between eukaryotic plant and animal cells.
Cell Wall
Chloroplast
Large Vacuole
Draw a graph showing an enzyme that is active from 2-10 on a pH scale. Draw the peak enzyme activity at 6.
Hold up your picture :)
Draw an example of the structure of a lipid. Label it as saturated or unsaturated.
Hold up your boards :)
Explain the endosymbiotic theory.
Because of this theory, it is believed a few organelles have their own DNA. Which organelles in a cell have their own DNA?
The theory states that eukaryotic cells originated from smaller prokaryotic cells being engulfed by larger prokaryotic cells.
Nucleus, mitochondria, chloroplast
Is a virus considered living or non-living? (You must include details to get credit for this question)
Non-living: needs an explanation using info of DOG RACE'M
What is the job of the golgi body?
It packages and "ships" materials
Draw and label a graph that shows how a catalyst changes the rate of a chemical reaction. You need two lines: a solid line representing an uncatalyzed reaction and a dashed line showing how an enzyme will affect/change the reaction.
Label the X and Y axis: Reaction Rate and Potential Energy
Use the words reactants and products.
Hold up your picture - do not erase or put it down!!!
List each of the four macromolecules and their monomers.
Carbohydrate = Monosaccharide
Lipid = Glycerol/Fatty Acids
Protein = amino acids
Nucleic Acid = Nucleotide
Create your own question that you would put on this benchmark. Each group will answer your question - do not erase it :)
Hold up your board :)
