Properties of Water
Which property of water allows plants to move water against gravity?
Capillary action- cohesion and adhesion
Theory that life must come from life.
What is the monomer of a lipid?
Fatty acid
What is the monomer of a carbohydrate?
Monosaccharide
What macromolecule is an enzyme made of?
Proteins
Which property of water allows it to transport sugars and nutrients?
Universal solvent
A mix of organic molecules could form in an oxygen deprived environment through random interactions of small molecules, with energy from the sun/lightning (theory).
Primordial Soup Theory
Which macromolecule contain a 1:2:1 ratio of C, H, O in a ring formation?
Carbohydrate
Which macromolecule contain C, H, O in a chain formation?
How do enzymes affect activation energy?
Decrease activation energy
What property of water allows fish to survive in the winter?
Expansion upon freezing
What did the Miller-Urey experiments demonstrate?
That organic molecules can be make from inorganic materials.
What molecule contains an amine group (N), a carboxyl group, a hydrogen, and variable "R" group?
Protein
Which macromolecule contains a phosphate group, a sugar, and a nitrogenous base?
What happens to an enzyme when the pH or temperature is beyond optimal levels?
Denatures
Water can dissolve compounds in which states?
Solid, liquid, gas
Bacteria were engulfed by larger cells (theory).
Endosymbiotic Theory
Make up the major structural material of plants and store/supply energy.
Carbs
Nucleic Acids
What is the function of an enzyme?
NOT how, but WHAT.
Build up or break down molecules.
Water's high specific heat and ability to moderate temperature come from which property?
Stong hydrogen bonds
Scientists speculate this molecule may have been the first organic molecule to evolve due to its role in reactions and storing genetic information (theory)
RNA world hypothesis
Allows membrane to carry out specific tasks, including cell division and movement
Proteins
This macromolecule makes up the bilayer membrane and regulates what materials enter/exit cell.
Lipids
How is an enzyme a biological catalyst?
It speeds up reactions in living organisms.
