Cards

Term
where is energy stored in organic molecules?
Definition
Chemical Bonds
Term
Kinetic Energy
Definition
Movement of high energy particles. Light is kinetic energy
Term
Potential Energy
Definition
Stored energy that can do work. Water behind a dam. Concentration gradients are potential energy
Term
Types of energy
Definition
Chemical Energy:Energy stored in chemical bonds(type of potential)
Term
Thermodynamics
Definition
Changing energy from one type to another
Term
first law of thermodynamics
Definition
1:Energy can not be created or destroyed only change forms
Term
Sencond law of thermodynamics
Definition
Energy transformation is not perfect and will result in some energy becoming heat
Quality of energy in the universe is decreasing
Term
Atp(adenine triphosphate)
Definition
Free floating molecule that is use to create energy for the cell.
Term
Atp structure
Definition
made of a sugar molecule attached to a molecule, which is attached to three negatively charged phosphate molecules which were energy is stored in the short term. when one of the phosphates is release so is the energy
Term
adp to atp
Definition
requires energy
Term
atp to adp
Definition
releases energy
Term
Photosynthesis
Definition
input: sunlight+water+co2
output: oxygen+sugar
Term
Chloroplast
Definition
organelle that allows plants to get energy from the sun
Term
Chloroplast anatomy
Definition
made up of the stroma and and thylakoids
Term
stroma
Definition
liquid that is floating in chloropast. this is where the synthesis part of photosynthesis occurs
Term
thylakoid
Definition
stacks of "pancakes" floating in the stroma where the photo part of photosynthesis happens
Term
Chlorophyll
Definition
the molecule in chloroplast that allows it to capture light
Term
light energy
Definition
kinetic energy powered by photons
Term
photons
Definition
photons are waves that do work by hitting and object and in turn make heat, the shorter the wave length the stronger the energy
Term
electromagnetic spectrum
Definition
the range of light waves from shortest to longest aka most energy to least energy
Term
pigments
Definition
molecules in our eyes that allow us to see
Term
"Photo" part of photosynthesis
Definition
Happens in the tylakoids, sunlight and water go in, atp, nadph and oxygen comes out
