Presentation Transcript

  1. Do Halobacteria grow best in the presence or absence of oxygen?

  2. Are halobacteria able to grow without oxygen? What data supports your conclusion?

  3. Halobacteria use bacteriorhodopsin (BR) to produce ATP using light energy LIGHT bacteriorhodopsin (BR) ATP ADP + P

  4. Halobacteria use bacteriorhodopsin (BR) to produce ATP using light energy LIGHT PRESENT LIGHT bacteriorhodopsin (BR) ATP ADP P

  5. Halobacteria use bacteriorhodopsin (BR) to produce ATP using light energy LIGHT PRESENT LIGHT bacteriorhodopsin (BR) ATP ATP ADP P

  6. Halobacteria use bacteriorhodopsin (BR) to produce ATP using light energy LIGHT LIGHT ABSENT (DARK) bacteriorhodopsin (BR) ADP + P

  7. LIGHT PRESENT LIGHT bacteriorhodopsin (BR) ATP ADP + P Halobacteria use bacteriorhodopsin (BR) to produce ATP using light energy LIGHT ABSENT (DARK) LIGHT bacteriorhodopsin (BR) ATP ADP + P

  8. Bacteriorhodopsin (BR) is made from bop protein and the molecule retinal bacteriorhodopsin (BR) bop protein retinal Drawing not to scale and shapes are over simplified!!!

  9. Light Halobacteria change their expression of BR in response to the amount of light in their environment Halobacterium cell Drawing definitely not to scale!!!

  10. Light bR Halobacteria change their expression of BR in response to the amount of light in their environment The amount of bR increases when there is more light. + Note that the size of nodes in this diagram relates to the amount of light and bR, not the actual size. In other words, the size of bR does not change; a larger node for bR indicates a larger amount of bR.

  11. OUR QUESTION: How do Halobacteria cells change the amount of bR in response to light?
