What is the difference between heterotrophs and autotrophs?
Autotrophs can make their own energy, while heterotrophs must consume other living things for energy.
100
two or more atoms chemically combined are called________.
compound
100
what is adhesion?
water sticks to something other than another water molecule
100
what is the difference between prokaryotes and eukaryotes?
prokaryotes= no nucleus or membrane bound organelles
eukaryotes= nucleus with membrane bound organelles
100
what molecules make up the cell membrane?
phospholipid

100
How is Botox taken into a neuron?
by receptor mediated endocytosis
200
correctly describe a controlled experiment
An experiment where only one variable is changed at a time
200
Which organic molecule does not form a POLYMER?
lipids
200
what is cohesion
water sticks to water
200
Name 4 things all cells have? (whether prokaryote or eukaryote)
cell membrane
cytoplasm
ribosome
DNA
200
Cholestrol is in the cell membrane bilayer. Is cholestrol polar or nonpolar.
nonpolar
200
What is the name of the enzyme that puts the carbon together?
rubisco
200
When someone drinks a lot of pure water in a very short period of time this condition may occur.
Hyponatremia
300
What is the difference between a dependent and independent variable in an experiment?
Independent = variable I changed aka the manipulated variable
Dependent= aka the responding variable -what is being measured as a result of what you manipulated
300
What type of organic molecule is this:
lipid (triglyceride)
300
why is a water molecule polar
uneven sharing of electrons
300
what is the function of the golgi apparatus ?
modify and package proteins for shipping out of the cell
300
What is the difference between passive and active transport?
passive= requires no energy molecules move from H-> L
active= requires energy molecules move from L->H
300
In the Leaf Chad lab, what molecule produced by photosynthesis caused the chads to rise in the presence of light?
Oxygen
300
If someone drinks milk and their blood glucose levels do not rise after 30 min are they lactase persistent or lactose intolerant? Explain your answer.
lactose intollerant- because the enzyme lactase is turned off and they cannot breakdown Lactose into Glucose and Galactose! Thereby increasing their blood glucose level.
400
what is a zygote?
fertilized egg
400
What are the atoms for:
Carbs
lipids
proteins
Nucleic acids?
Carbs= C,H,O
Lipids= C,H,O
Proteins= C,H,O,N
Nucleic Acid= C,H,O,N,P
400
what is the bond that allows one water molecule to bond with another water molecule?
hydrogen bond
400
name the cell support structures (not the cell wall)
cytoskeleton- microtubules and micrfilament
400
what is facilitated diffusion?
Facilitated diffusion is passive transport of larger molecules that require help getting through the membrane. The help is with transport proteins like a channel protein
400
What are the 2 reactants in photosynthesis?
CO2 + H2O
400
Ach is a ligand that enables a muscle cell to contract. Explain how this works.
Ach is released into the snaptic gap and goes into the ligand site on the gated channel protein causing it to open and allow ions to flood the muscle cell which causes a contraction.
500
What is the difference between the constants and the control in an experiment.
constants= what the experimenter keeps the same in the different setups
control= the variable that is in most natural state. what you are comparing the IV to.
500
What are the monomers for:
Carbs
Lipids
Proteins
Nucleic Acids
Carb= monosaccharide
lipid= triglyceride
protein= amino acid
Nucleic Acid= nucleotide
500
Label the parts of the following diagram illustrating the catalytic cycle of an enzyme. (skip E)
a=enzyme
b=active site
c= substrate
d= enzyme substrate complex
f= products
500
Name 2 types of cells that have a cell wall
prokaryote and plant cell
500
Expelling large molecules from the cell occurs through this process
EXOCYTOSIS
500
Where did the leaf Chad get the CO2 from in our experiment?
baking soda
500
Why can cows digest cellulose but we can't?
cows have microorganisms that break down (HYDROLYZE) the bonds in cellulose and they can use the glucose for energy
600
How do you write a CER?
C= answer the question asked
E= data (quantitative and qualitative) with units
R= C+E+ scientific concept involved.
600
Which of the 4 organic molecules would you say polysaccharides are?
carbohydrates
600
what is anabolism and catabolism?
anabolism= put molecules together
catabolism= take molecules apart
600
correctly matchthe product to the location of the cell during the milk secretion process
milk protein?
milk sugar?
milk Fat?
protein= ribosome
fat= Smooth ER
sugar = gogi apparatus
600
define dynamic equilibrium.
dynamic equilibrium is when there is an equal percentage of solutes and solvents on both sides of the membrane
600
what are the chemical equations for cell respiration and photosynthesis?
6H20+ 6CO2 + sunlight energy-> C6H12O6+ 6O2
C6H12O6+ 6O2->6H20+ 6CO2+36 ATP
600
What is the difference between these two enzyme regulators: Allosteric inhibitors and Allosteric activators/enhancers ?
allosteric inhibitors have a molecule that binds with the allosteric site shutting down the availability of the active site.
allosteric activators have a molecule that binds with the allosteric site allowing the availability of the active site.
