What cellular features and processes are similar in both photosynthesis and cellular respiration? Both processes are contained in organelles with single membranes, and both use a version of the cytochrome complex. Both processes are contained in organelles with double membranes, and neither use a version of the cytochrome complex. Both processes are contained in organelles with double membranes, and use a version of the cytochrome complex.

In what part of chloroplasts do the coupled redox reactions occur? stroma membrane thylakoid membrane intermembrane space thylakoid lumen stroma
In 2005, a new species of green sulfur bacteria was discovered near a geothermal vent at the bottom of the ocean. An exceptionally efficient light-harvesting mechanism allows these bacteria to carry out photosynthesis where the only illumination is a dim volcanic glow emanating from the vent. Cell membrane are required for electron transfer chains in the light-dependent reactions. but these bacteria have no internal membranes. How do you think they carry out the light-dependent reactions?

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?
