Lab Chemistry Parts of a Cell Proteins Misc.
100
What is lab safety?
Procedures and mindsets that are followed in lab so that people don't die or get hurt
100
What is a peptide bond?
bond between two amino acids, often formed in a sequence between an amine and carboxyl group
100
What is a Eukaryotic cell?
Subunit of life that contains a nucleus and membrane bound organelles
100
What is an enzyme?
Biological molecule that reduces the activation energy of a reaction.
100
What is the central dogma?
DNA --> RNA --> Protein
200
What is fluorescent microscopy?
Technique used in lab that works by tagging parts of a cell with a dye that emits light when activated by a certain wavelength
200
What is a hydrogen bond
Non-covalent force between an Oxygen or Nitrogen and a partially positive hydrogen
200
What is a protein?
The most abundant macromolecule in the body. Makes up 15% of the cell.
200
What is N-terminus?
Amine end of polypeptide chain
200
What is hydrolysis?
A process that involves breaking a saccharide, using a molecule of H2O in the process
300
What is a model organism?
Often studied in labs due to the universality of life
300
What is the hydrophobic effect?
the observed tendency of non-polar substances to aggregate in an aqueous solution and exclude water molecules.
300
What is a nucleus?
Largest organelle in the body. Organizes and stores genetic information.
300
What is an alpha helix?
Secondary structure that has all side chains facing outward and has a hydrogen bond along the backbone every 3-4 subunits
300
What is anabolism?
A process that builds things fro smaller units and tends to require energy
400
What is a centrifuge?
Instrument that uses g force to separate parts of a cell by density
400
What is amphipathic?
Used to describe something that has a hydrophobic and hydrophilic site
400
What is Cytoplasm?
the material within a living cell, excluding the nucleus.
400
What is tertiary structure?
Dictated by the hydrophobic effect as well as the electrostatic interactions between side chains
400
What is cell theory?
All living things are made from cells. Cells are a fundamental unit of life. All cells come from cells
500
What is urea?
Chemical that is commonly used for unfolding proteins
500
What is reduction?
Describes the increase in the number electrons to a model. NADH is an agent of this
500
What is an intermediate filament?
subcategory of the cytoskeleton that provides tissue structure by having protein interactions outside of the cells. Is the reason why skin cells can stretch without blistering or breaking
500
What is a dimer?
can be formed when two of the same protein have a hydrophilic surface exposed to the cytosol
500
What is an active carrier?
molecules responsible for carrying energy from one molecule to another
