MODULE 2 (SET D) Flashcards
(43 cards)
the application of probability and statistics to large populations of molecules
STATISTICAL MECHANICS
mathematical description of how molecules move, how much energy they have, how they change shape
MODEL
TRUE OR FALSE: The probability of a protein molecule undergoing a shape change needed for its function utilizes model
TRUE
can be used to calculate and predict thermodynamic quantities such as temperature, pressure, and amount of energy released or absorbed
STATISTICAL AVERAGES
allows us to interpret the things we can measure in terms of what specific molecules are doing
STATISTICAL MECHANICS
deals with measuring the rate of speed of biological processes such as biochemical reactions, conformational transitions, and binding or unbinding of biomolecules
KINETICS
Tells us whether a given process or biochemical reaction will occur.
THERMODYNAMICS
Tells us how fast a given process or biochemical reaction will occur.
KINETICS
The temporary unwind of DNA is the ____________ energy state of DNA
higher energy
what is the lower energy state of DNA
double helical state
TRUE OR FALSE: The unwound double helix is the high energy intermediate in the process of DNA replication.
TRUE
device that can alter the direction and/or size of a force
Machine
special type of machine that also has the ability to convert potential energy into mechanical energy
Motor
TRUE OR FALSE: Muscles use our bones as levers to redirect and in some cases magnify or decrease the forces they apply.
TRUE
TRUE OR FALSE: Muscles are motors.
TRUE
hairlike projections on the surface of some cells; present on the inner surface cells of the lungs
CILIA
These are longer, whiplike structures that stick out from the body of some cells; move to propel the cell forward
FLAGELLA
move by temporarily pushing out on their membrane at one or more locations, changing the shape of the cell
PSEUDOPODIA
cells that manufacture proteins or other substances to be used elsewhere in the body
SECRETORY CELLS
When a cell is getting ready to divide, it first duplicates its chromosomes
Separation of Chromosomes during cell division
motion generated by muscle contraction was due from
individual molecules of one protein (myosin) binding to and pushing against the molecules of another protein (actin)
binding in one part of a molecule affects activity in another part of the same molecule
allostery
Greek word means “other”
allos
Greek word for object or solid object
stereos
