Homework Answers
- Photosystem I (PSI) absorbs the longer wavelength of light at 700nm. Photosystem II (PSII) absorb shorter wavelength of light at 680nm. In PSI photolysis does not take place but takes place in PSII.PSI performs important functions in both cyclic and non-cyclic photophosphorylation but PSII takes part only in cyclic photophosphorylation. PSI receives electrons from PSII and synthesizes NADH, PSII hydrolyzes water and synthesizes ATP.
- We need oxygen mainly because it is required for the living cells to release energy in the form of ATP through Electron Transport Chain in mitochondria. Some biochemical reactions also need oxygen to happen.
- No, Calvin cycle cannot sustain if it is kept in darkness for several hours. This is because it is dependent on the light reactions for ATP and NADPH. NADPH is very unstable molecule so that needs to be utilized instantly after synthesis by the light-dependent reaction.
- The correct answer is - ATP . Enzyme carrying molecule is the co-enzyme of an enzyme and among the given options ATP acts as coenzyme of many enzymes.

The Calvin Benson cycle use the energy trapped in ATP and NADPH generated by the light reactions to build sugars from CO2. What below is FALSE regarding this sugar-building cycle? Select one: a. Initially RuBP is carboxylated by RuBisCo where atmospheric CO2 is captured and put into the cycle. b. ATP and NADPH generated by the light reactions are used to reduce 3PG to a more energetic/reduced G3P (some of which will be diverted off to build sugar!) c. More...
