Why does cyanide inhibit electron transport but not photosynthesis?O In animals cyanide binding to complex IV blocks electron transport and therefore ATP synthesis, in photosynthesis thiscomplex has other hemes that cyanide cannot bind and therefore is not inhibited.O In animals cyanide binding to complex IV blocks electron transport and therefore ATP synthesis, in photosynthesis thiscomplex is not used and therefore is not inhibited.O In animals cyanide binding to complex IV prevents hydrogen gradient formation and therefore ATP synthesis, inphotosynthesis this complex is not used and therefore is not inhibited.O In animals cyanide binding to complex IV blocks electron transport and therefore ATP synthesis, in photosynthesis usesmultiple complex IVs that cyanide cannot bind and therefore is not inhibited.

Plant chloroplasts are able to generate which of the following inorganic product molecules during oxygenic photosynthesis? cell biology C6H12O6 CO CO2 O2 H2S
What properties of photosynthetic pigments allow pigments to absorb light of only certain wavelengths? Select all that apply. Some pigment molecules lack a light-trapping region. Light of any energy level can boost an electron of the pigment molecule to a higher energy level in order to be absorbed. Only light with the correct wavelength to boost an electron of the pigment to a higher energy level is absorbed. All pigment molecules possess a light-trapping region with a special structure that allows electrons to move freely between its atoms.

A culture of the single celled organism Chlamydomonas is actively carrying out photosynthesis in the presence of light and CO2. If you turned off the light, how would you expect the amounts of ribulose 1,5-bisphosphate and 3-phosphoglycerate to change over the next minute? How about if you left the light on and removed the CO2?
Which of the following statements about photosynthesis is NOT true? Light independent reactions are very similar to the electron transport chain of cellular respiration Light is absolutely essential for both aspects of photosynthesis In order replace electrons, water is split to form oxygen gas Light dependent reactions are very similar, but in reverse, to the Krebs cycle and glycolysis
