(158 cards)
the energy of life begins as …, created by …, traveling out of the sun at the speed of light
photons; nuclear fusion
electromagnetic radiation is composed of an oscillating wave of … and … fields which travel through space
magnetic; electric
The distance between the crests of the waves determines the …, and the number of crests per unit time determines the …
wavelength; frequency
wavelength =
speed of wave/frequency
the wavelength and frequency of the electromagnetic radiation in a photon determines the … in that photon
short wavelength = … frequency = … energy
long wavelength = … frequency = … energy
energy; high; high; low; low
when the wavelength of electromagnetic radiation is between … and … nm, it can be detected by the human eye and is called …
400; 700; visible light
visible light is only a small portion of the entire
light spectrum
light that we see is because the object is … some light waves while … others. White light contains …
absorbing; reflecting; all color wavelengths
pigments are substances that have the ability to … we perceive their color as the … that they are not able to absorb
absorb light; wavelengths
when electromagnetic radiation is absorbed, the energy contained in the photon is transferred to an … which allows it to become …
electron; excited
Excitation means that the electron moves from a … (…) to a …
low energy level; ground state; higher energy level
has to absorb energy … than color transmitted
higher
ATP is the currency of … in living systems. It stores the energy gained in … reactions to power … reactions at a later time and provides the … for the processes of life
energy; exergonic; endergonic; energy
ATP includes three … each of which has an ionic charge of …
phosphate groups; -3e
The phosphate groups in ATP … each other, since they each have a negative charge. Thus, it requires … to add the second phosphate group –> to go from … to …
To add the third group, to go from … to … requires even more since it is repelled by both of the other phosphate groups
repel; work; AMP; ADP; ADP; ATP
the energy from the work needed to bring each phosphate group to the molecule is stored in that … When it is broken to go from ATP to ADP, significant … is released. Going from ADP to AMP releases …, since there is … total … in ADP than ATP
phosphate bond; energy; less energy; less; charge
In living systems, the energy from the exergonic reaction of ATP hydrolysis can be used to drive an … (…, …)
this is known as
endergonic reaction; anabolism; dehydration synthesis; coupling
ATP drives endergonic reactions by …, transferring a … to some other molecule, such as a reactant. The recipient molecule is now …
phosphorylation; phosphate group; phosphorylated
The three types of cellular work are powered by the hydrolysis of ATP: …., …, …
mechanical; transport; chemical
mechanical: …., differs from transport, as transport uses …
moving parts; membranes
ATP is a … resource that is regenerated by addition of a … to …
renewable; phosphate group; ADP
the energy to phosphorylate ADP comes from … in the cell. Each cell is converting millions of ATP to ADP and back again each second –> ATP is …
catabolic reactions; transient
photosystems are utilized for …, and are embedded in the membranes. They are therefore a type of … The membrane is required to establish the … for the synthesis of …
transport; transport protein; proton gradient; ATP
the first step in the process is when sunlight … in the pigment of the system
