5 Multiple Choice Questions
- green pigment in plants that absorbs light energy used to carry out photosynthesis
- One of two light-harvesting units of a chloroplast's thylakoid membrane; it uses the P680 reaction-center chlorophyll.
- in chloroplasts, an acceptor of electrons lost from chlorophyll a; found in the thylakoid membrane
- that portion of the electromagnetic spectrum detected as various colors by the human eye, ranging in wavelength from about 380 nm to about 750 nm.
- The process of generating ATP from ADP and phosphate by means of a proton-motive force generated by the thylakoid membrane of the chloroplast during the light reactions of photosynthesis.
5 True/False Questions
photosystem I → One of two light-harvesting units of a chloroplast's thylakoid membrane; it uses the P700 reaction-center chlorophyll.
Light Reactions → organism that obtains energy from the foods it consumes; also called a consumer
PEP Carboxylase → An enzyme that adds CO2 to phosphoenolpyruvate (PEP) to form oxaloacetate in C4 plants. It acts prior to photosynthesis.
NADP → one of the carrier molecules that transfers high-energy electrons from chlorophyll to other molecules
G3P → 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
