ECU Biology 1100 Exam 2 Study
Questions and Solutions
Photo system ✅consists of a reaction center in the complex (a type of protein
complex) surrounded by light-harvesting complexes

Photo system II (PS II) ✅Functions first; best at absorbing a wavelength of 680nm

Photo system I (PS I) ✅Best at absorbing wavelength of 700nm

Linear Electron flow ✅Flow of electrons through photosynthesis

Carbon Fixation (Calvin Cycle) ✅Incorporation of CO2 molecules in rubulous bi-
phosphate (RuBp); using enzyme "rubisco"; product is 3-phosphateglycerate (phase 1)

Reduction (Calvin Cycle) ✅Involves reduction and phosphorylation of 3-
phosphogyclerate to sugar (GP3); 6ATP and 6 ADPH are needed to make 6 G3P
(phase 2)

Regeneration (Calvin Cycle) ✅Involves rearrangement of 5 remaining G3P to make
RuBP; 3 more ATP needed (Phase 3)

Photosynthesis ✅the process that converts solar energy into chemical energy

Photosynthesis (equation) ✅6CO2 + 12H2o + Light energy -> C6H12O6 + 6O2 +
6H2O

Chloroplast ✅Site of photosynthesis in plants

Chlorophyll ✅Green pigment in plants that absorbs light energy used to carry out
photosynthesis

Mesophil ✅Interior tissue of the leaf

Stoma ✅CO2 enters; O2 exists through these parts

Thylakoids ✅Connected sacs of membrane in the chloroplast

Stroma ✅Dense interior fluid

Light reaction ✅Part of photosynthesis that involves light. ATP and NADPH are
produced. Takes place on the thylakoid membrane.
