General Concepts and Biophysical Principles Flashcards
a branch of science that is concerned with the application of physical principles and methods to biological problems
Biophysics
the science dealing with how physics applies to the process of biology
Biophysics
seeks to explain biological function in terms of the physical properties of specific molecules
Biophysics
study of physical phenomena and physical processes in living things on scales spanning molecules, cells, tissues, and organisms
Biophysics
the study of life and organisms
biology
the study of cells as basic structural units of life, genetics and heredity, and transformation of energy by organisms while growing, developing and adapting to their environment
basic biological concept
the study of energy and matter and how the two interact through time and space
physics
it explains that, when scientist combine physics and biology, they learn more about biological systems on a molecular or anatomic level
biophysical society
who said that everything on earth is made of atoms, basic units of matter, that constantly move
Richard Feynman
define as the change in position with respect to time
motion
motion can either be described as:
- change in speed
- change in direction
occurs when a chemical or chemicals convert into another substance
chemical reaction
means that two elements combined to make something new
synthesis
two chemicals make a new substance
direct combination reaction
occurs when a chemical combines with oxygen
combustion
when one chemical reacts to a stimulus by breaking into two simpler elements
decomposition reaction
uses electricity to break bonds
electrolytic decomposition
breakdown chemicals with heat
thermal decomposition
when a complex chemical is exposed to photons from light
photo decomposition
the chemical reaction that takes an element away from a compound and adds it to another substance
single replacement chemical reaction
when you have two complex reactants that’s what chemicals during a reaction, you get two new products
double replacement or metathesis reaction
reactions that use an acid and a base as reactants
neutralization
considered among the most ancient objects of biophysical exploration
bioluminescence
the first scientific investigation of animal luminescence was that of, who devoted two chapters of his book Ars Magna Lucis et Umbrae to bioluminescence
Athanasius Kircher, a 17th century german jesuit priest
wrote of “a certain most subtle spirit which pervades and lies heat in all gross bodies”
Isaac Newton in the Principia (1687)
wrote the details of his discovery of the electrical nature of the discharge from the torpedo or electric ray
John Walsh in 1773
“gang of four” got together to develop a research program based on the rejection of the, at the time, prevailing notion that living animals depend on special biological laws and vital forces would differ from those that offered in the domain of inorganic nature
- Emil de Bois-Reymond
- Ernst von Brucke
- Hermann von Helmholtz
- Carl Ludwig
introduce the term “Bio-Physics” in The Grammar of Science to describe the science that links the physical and biological sciences
Karl Pearson
how old is biophysics
only about 60 to 100 years old
when Francis Crick found out about double helix DNA
1953
the year the biophysical society was founded
1957
the study of structure and function of cell membranes, including the ion channels, protein, and receptors embedded in them
membrane biophysics
using mathematical modeling to study biological systems
computational or theoretical biophysics
creating and modifying proteins to advancing synthetic biology. often used to advance human health in the form of new disease treatments.
protein engineering
biophysics studies of biological molecules including proteins, nucleic acid, and lipids
molecular structure
using physical mechanism to explain the occurrence of biological processes
mechanism
