- Cyclic electron flow
- photosystem II
- a One of two light-harvesting units of a chloroplast's thylakoid membrane; it uses the P680 reaction-center chlorophyll.
- b A flattened membrane sac inside the chloroplast, used to convert light energy into chemical energy.
- c 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
- d process by which plants use the sun's energy to convert water and carbon dioxide into sugars
- e A metabolic pathway that consumes oxygen, releases carbon dioxide, generates no ATP, and decreases photosynthetic output.
5 Multiple Choice Questions
- the synthesis of organic compounds from carbon dioxide, such as in photosynthesis
- type of plant that minimizes photorespiration by fixing carbon twice, using a C4 pathway in addition to the Calvin-Benson Cycle.
- almost identical to chlorophyll a, but slightly different absorption spectra, yellow-green
- Store the organic acids made at night in vacuoles and use them for photosynthesis during the day when stomata are closed
- one of the carrier molecules that transfers high-energy electrons from chlorophyll to other molecules
5 True/False Questions
Calvin Cycle → reactions of photosynthesis in which energy from ATP and NADPH is used to build high-energy compounds such as sugars
photophosphorylation → A metabolic pathway that consumes oxygen, releases carbon dioxide, generates no ATP, and decreases photosynthetic output.
Photon → a tiny particle or packet of light energy
heterotroph → plant capable of synthesizing its own food from simple organic substances
Mesophyll → green pigment in plants that absorbs light energy used to carry out photosynthesis
