Group Specifics
unaturated fats is what state of matter at room temp? why?
Liquid because they tend to have kinks so they cant pack together tightly
List the 4 organic Macromolecules
proteins, lipids, carbohydrates, nucleic acids
Is water non polar or polar? Why?
polar because it has non covalent bonds which means that the electrons in a water molecule aren't shared equally
Organic compounds contain _____ to _____ bonds
carbon, hydrogen
What is pH stand for?
potential hydrogen
Plant polysaccharides and their function
Cellulose and Starch; structural component of the cell wall and a storage form in plants
7 characteristics of living things
cellular organization, reproduce, growth &development, utilize energy, respond to the environment, evolution, homeostasis
define cohesion and adhesion
the attraction between particles of the same substance
the attraction between two different types of molecules
how many atoms can carbon bond to ?
4
The scale ranges from ___ to ___ and the neutral is ___
0, 14, 7
name one example for monosaccharides and disaccharides OR fats/triglycerides, phospholipids, and steroids
1A. glucose, fructose, galactose; maltose, sucrose, lactose
2A. saturated/unsaturated fats; lipid bilayer; cholesterol, testosterone, progesterone, and estrogen.
Name the 4 organic macromolecules
lipids, protein, nucleic acids, and carbohydrates
How does waters polarity lead to hydrogen bonding?
When the partial negative oxygen of one water molecule becomes attracted to the partial positive hydrogen of a different molecule a hydrogen bond forms between them
What is an isomer?
compounds with the same molecular formula but different structure
Range of Acids and does it have higher H+ or OH- concentration? the closer to the number __ the more acid
0-6, H+, 0

How many water molecules can attach to one water molecule?
4
polymers vs monomers (what are they?)
polymers are long molecules consisting of many similar building blocks and monomers are the smaller building blocks
Rage of bases on the scale and does it have a higher H+ OR OH- concentration? What are they called because they readily accept H+ ?
8-14, OH-, Proton acceptors
Identify the major parts of a feedback loop and define negative and positive feedback loops. List examples of each.
A. stimulus -> detected by -> Receptor ->sends message to -> control center -> sends message to -> affecter -> feedback response -> actual feedback
B. Negative feedback loop lessens the stimulus it negates it and tries to shut it off and example would be temperature
C. positive feedback loops is an output of system that enhances the original stimuli making it stronger not weaker. An example could be childbirth or blood clotting
7 classes of proteins
1. Structural
2. Contractile
3. Storage
4. defensive
5. Transport
8. Signaling
9. Enzymes
Which molecule in H20 is electronegative?
oxygen
Explain Hydrolisis or Dehydration Synthesis (you can draw to explain)
A1. involves the addition of water, which breaks up a polymer, apart into monomers
A2. H is put back on one monomer and OH is put back on another
B1. an OH group one monomer and an H from another combine to form water (H20)
B2. water is then removed linking the two monomers together by a glycosidic linkage
what is a buffer?
substance that minimizes change in pH and keep the pH fairly constant within a solution
