5 Matching questions
- photosystem II
- Carbon fixation
- a process by which plants use the sun's energy to convert water and carbon dioxide into sugars
- b the synthesis of organic compounds from carbon dioxide, such as in photosynthesis
- c A flattened membrane sac inside the chloroplast, used to convert light energy into chemical energy.
- d a 3 carbon sugar; for each CO2 are formed in the Calvin cycle; 1 leaves to be used in the cell, 5 are use for regeneration of RuBP
- e One of two light-harvesting units of a chloroplast's thylakoid membrane; it uses the P680 reaction-center chlorophyll.
5 Multiple choice questions
- a tiny particle or packet of light energy
- almost identical to chlorophyll a, but slightly different absorption spectra, yellow-green
- An instrument that measures the proportions of light of different wavelengths absorbed and transmitted by a pigment solution.
- one of the carrier molecules that transfers high-energy electrons from chlorophyll to other molecules
- The distance between crests of electromagnetic waves.
5 True/False questions
primary electron acceptor → in chloroplasts, an acceptor of electrons lost from chlorophyll a; found in the thylakoid membrane
PEP Carboxylase → yellow or orange pigment that serves as an accessory to chlorophyll in photosynthesis
Autotroph → organism that obtains energy from the foods it consumes; also called a consumer
Cyclic electron flow → A route of electron flow during the light reactions of photosynthesis that involves only photosystem I and that produces ATP but not NADPH or oxygen
photophosphorylation → A metabolic pathway that consumes oxygen, releases carbon dioxide, generates no ATP, and decreases photosynthetic output.
