Biology Energy and Photosynthesis Quiz

TermDefinition
Energy the ability to do work
Adenosine Triphosphate (ATP) consists of adenine, a 5-carbon sugar called ribose, and three phosphate groups
Adenosine Diphosphate (ADP) consists of adenine, a 5-carbon sugar called ribose, and two phosphate groups
Photosynthesis the process that autotrophs use to convert the energy of sunlight into chemical energy stored in the bonds of carbohydrates
Heterotrophs organisms that obtain food by consuming other living things
Autotrophs organisms that make their own food
Visible Light Spectrum the different wavelengths of light that we see as the colors red, orange, yellow, green, blue, indigo, and violet
Pigments light-absorbing molecules that plants use to gather the sun's energy
Chlorophyll the plants' principal pigment for gathering the sun's energy
Chloroplasts organelles in plant cell where photosynthesis takes place
Thylakoids saclike photosynthetic membranes inside chloroplasts which are interconnected are arranged in stacks known as grana
Stroma the fluid portion inside of chloroplast but outside of the thylakoids
Electron carrier a compound that can accept a pair of high-energy electrons and transfer them, along with most of their energy, to another molecule
NADP+ (nicotinamide adanine dinucleotide phosphate) a carrier molecule
Chemical reaction process in which reactants are transformed into products after passing through a high energy transition state
Reactants a substance that takes part in and undergoes change during a reaction
Products substances formed during a reaction
Glucose sugars generated by photosynthesis to produce complex carbohydrates such as starches, and to provide energy for the synthesis of other compounds, including proteins and lipids
Light-dependent reactions reactions that require the direct involvement of light and light-absorbing pigments
Light-independent reactions reactions do not require direct involvement of light
