Let's "Cell-ebrate" Life! [Lecture 1]
Evidence based process of inquiry to investigate the natural world.
What is science?
The change of populations of species over time.
What is evolution?
Protons, Neutrons, Electrons are the three _______ of an atom
What are subatomic particles?
Proteins, Lipids, Carbohydrates, & Nucleic Acids
What is a biomolecule?
What is denaturation?
The 3 broad groups that categorize living organisms of simple cells, various protists, or the kingdom of fungi, plantae, & animalia.
What is Domain Archaea, Domain Bacteria, & Domain Eukarya
When humans choose a specific breed of the population and only breed the ones with the most desirable qualities.
What is artificial selection?
Electrons gain and loss create charged atoms. These are called ____________.
What is an ion?
Starches, sugars, glycogen, fibers, and chitin are all examples of which biomolecule?
What is a carbohydrate?
A protein made by living organisms to help speed up [catalyze] chemical reactions.
What is an enzyme?
Observation, hypothesis, prediction, tests of hypotheses via experiments or additional observations, and analysis of data.
What is the Scientific Method?
The universal chemical language which translates the information stored in DNA into proteins.
What is genetic code?
A weak bond characterized by a partially positive hydrogen on one molecule, and a partially negative atom on another molecule.
What is a Hydrogen Bond?
A structure where 3-5 amino acids will have hydrogen bonds that cause the structure to coil.
What is an Alpha Helix?
The molecule that binds into the active site is the ________.
What is the substrate?
Order, Reproduction, Growth & Development, Response to an Environment, Energy Processing, Regulations, Evolutionary Adaptations.
What are the 7 properties of life?
Adenine, Thymine, Cytosine, & Guanine
What are DNA Nucleotides?
Atoms gain or lose electrons to attain the most stable electron shell configuration - an octet (8)
What is the octet rule?
This structure is formed when a hydrogen bond between the carboxyl oxygen and an amino hydrogen that are on the same backbone of the amino acid sequence.
What is a Beta Plated Sheet?
The amount of energy required for the molecules to be in their higher energy/unstable state, so that the "downhill" part of the reaction can happen.
What is Activation Energy?
The result of interactions between the components of a system [for example: Ant colonies; multiple ants working together can build dams and mounds and transfer large amounts of food from one area to another.]
What are emergent properties?
The process that uses energy from sunlight, CO2 and H2O [matter] and converts it into sugar molecules with stored chemical energy
What is photosynthesis?
A ____ of 7 is considered neutral, a ____ above 7 is considered basic, and a _____ below 7 is considered acidic.
What is pH?
During *this* reaction between two monomers, each of the monomers has a hydrogen and a hydroxyl group:
When hydrogen is removed from the monomer & a hydroxyl group from another, the hydrogen and hydroxyl combine to form water, and a bond will link the two monomers.
What is dehydration synthesis?
During *this* reaction, a biomolecule is built into polymers and because the products can hold more stored energy than it's reactants, energy will be added.
What is an endergonic reaction?
