AP Biology Photosynthesis Crossword

Across
A stack of membrane-bounded thylakoids in a chloroplast where light energy is trapped by chlorophyll and converted to chemical energy during the light reactions of photosynthesis
reactions in photosynthesis that require light energy that is captured by chlorophyll to be converted into chemical energy in the form of ATP and NADPH
A product of photosynthesis that serves as the building block for polysaccharides
A series of electron carrier molecules that shuttle electrons during a series of redox reactions that release energy used to make ATP; located in the inner membrane of mitochondria, the thylakoid membranes of chloroplasts, and the plasma membranes of prokaryotes
The entire spectrum of electromagnetic radiation ranging in wavelength from less than a nanometer to more than a kilometer
The production of ATP by chemiosmosis during the light reactions of photosynthesis
The scientist who demonstrated that the site of photosynthesis is the chloroplast and proved only specific wavelengths can be used for photosynthesis    
  a round or succession of observable phenomena, recurring usually at regular intervals and in the same sequence- example is the calvin cycle
low molecular weight iron sulphur proteins that transfer electrons from one enzyme system to another without themselves having enzyme activity
The reaction center chlorophyll (or the primary electron donor) of photosystem II that is most reactive and best in absorbing light at wavelength of 680 nm
Light energy absorbed by chlorophyll molecules built into the thylakoid membranes is used to drive the transfer of electrons and H+ from water to the electron acceptor NADP+ reducing it to ______
The dense fluid within the chloroplast that surrounds the thylakoid membrane and is involved in the synthesis of organic molecules from carbon dioxide and water
An enzyme that catalyses a reduction
Leaf cells specialized for photosynthesis; a leaf’s ground tissue system
Down
A photosynthetic complex containing chlorophyll and initiates the initial electron transfer reactions of photophosphorylation
A specialized cell type in a multicellular organism that is sensitive to light
 A cluster of several membrane proteins that function in chemiosmosis with adjacent electrontransport chains, using the energy of a hydrogen ion concentration gradient to make ATP
An enzyme vital in CAM and C4 plants during photosynthesis
the light-requiring part of photosynthesis plants, in which an electron donor is required, and oxygen is produced as a waste product. It consists of two photoreactions, resulting in the synthesis of ATP and NADPH
The reaction-center complex contains a pair of special chlorophyll a molecules and a molecule called the__________ which is capable of accepting electrons and becoming reduced
The absorption and the immediate re-emission of light or photon, which has longer wavelength when re-emitted than that of what was previously absorbed
microscopic pores surrounded by guard cells in the epidermis of a leaf. When these are open, CO2 enters a leaf, and H2O and O2 exit. A plant conserves water when they are closed
an indicator of which wavelength of light can be used by a plant to allow photosynthesis   
A flattened membranous sac inside a chloroplast containing chlorophyll and the molecular complexes of the light reactions of photosynthesis
The nonpolar reactant of photosynthesis
The scientist who proved oxygen comes from H2O not CO2
A fixed quantity of light energy. The shorter the wavelength of light, the greater the energy
The product of photosynthesis serving as a waste product to the plant
as H+ accumulate inside the thylakoid during  light reactions this occurs
Nicotinamide adenine dinucleotide phosphate, an electron acceptor that temporarily stores energized electrons produced during the light reactions
