Monomers
What is the monomer for Nucleic Acids
Nucleotide
Which Macro-Molecule acts as the main and most readily used energy source for living things but can also provide energy storage and structure
Carbohydrates
Name the 4 Main Biochem Molecules (Macro-molecules)
Protein, Carbohydrates, Lipids, Nucleic Acids
Is H20 needed for life as we know it?
YES!!!!!!!!!!!!
What Macro-Molecules form the cell wall?
Lipids and Proteins
Monomer for Protein
Amino Acids
Name one of the main purposes of Proteins?
1.Control the rate of reactions and regulate cell processes. (enzymes are proteins)
2.Used to form bones and muscles
3.Transport substances into or out of cells or help to fight disease (these proteins are part of the cell membrane.
Difference between Monomer/Polymer.
Monomer-basic unit (1)
Polymer-Many monomers bonded together
True or False? H20 is a nonpolar molecule.
False. It is polar.
True of False: Enzymes speed up the time it takes reactions to produce product. At the end of the reaction enzymes become a part of the finished product.
False. Enzymes are a catalyst so are never used as part of a product. They are the same before and at the end of the reaction.
Lipids have what monomer?
Fatty Acids
Which Macro-Molecule provides long term energy (storage) & structure (Cell Membrane), cushions the body, and prevents heat loss
Lipids
What Elements are found in all 4 Macro-molecules?
C,H,O
List the properties of Water?
Polarity, Cohesion, universal solvent, cohesion, adhesion, high specific heat
Technically Surface Tension
What type of Nucleic Acid only exists as a monomer? Never bonds with others.
ATP- the energy molecule for all living things.
Name the Monomer for Carbohydrate, as well as the other 2 levels of bonded carbs. Monomer->Polymer
Monosaccharide
Which Marco-molecule makes up the blue print or instruction manual for all living things?
Nucleic Acids in the form of DNA
Which Macro-Molecule directly control the synthesis or construction of a different Macro-molecule?
Nucleic acids, as RNA, control the synthesis or construction of Proteins.
Difference between cohesion and adhesion.
Cohesion: H2O bonded to H20
Adhesion: H20 bonded to non-H20 or different type of molecule
Describe what aspect of water on the molecular level gives it such a high specific heat.
Hydrogen bonding. These are the strongest types of bonds between molecules. Since H20 grabs onto another H20 with these really strong hydrogen bonds, a lot of energy, or heat, is needed to break them. Evaporation only happens if there is enough heat to break the bonds between water molecules.
True or False? A Lipid is made up of only 3 fatty acid molecule.
False. Made up of 3 Fatty Acids bonded to a Glycerol.
Which of the 4 Macro-Molecules are needed for life to exist?
ALL OF THEM!!!!!! ALL 4 ARE NEEDED FOR LIFE!!!!!!!!
List the elements inside each Macro-molecule.
Carb? Lipid? Protein? Nucleic Acid?
CHO
CHO
CHON
CHONP
Describe capillary movement in plants.
A few Water molecules are pulled through the roots through adhesion and drag other water molecules with them through cohesion.
How does water having a lower density as a solid, ice, benefit living things? How does ice floating on water help living things survive?
Ice floats to the top as it freezes, allowing construction of new ecosystems on top of the ice (as seen in the arctic). It also forms a seal over the top of lakes/ponds so that the entirety of the body of water will not freeze, allowing underwater ecosystems to survive the winter unfrozen.
