A scientist is using a species of green algae to study the electron transport chain in photosynthesis. He uses a laser to inacti
jeka94

Answer:

D) In case 1, both PS I and PS II completely lose function; in case 2, a proton gradient is still produced.

Explanation:

The light dependent reaction of photosynthesis, which produces the ATP and NADPH needed in the light independent stage of the process, includes complexes of proteins and pigments called PHOTOSYSTEMS. These photosystems (I and II) are key to the functionality of the light dependent reactions in the thylakoid.

The major pigment present in both photosystems is CHLOROPHYLL A, which absorbs light energy and transfers electrons to the reaction center. Chlorophyll B is only an accessory pigment meaning it can be done without. Hence, if all of the chlorophyll A is inactivated in the algae but leaves chlorophyll B intact as in case 1, both PS I and PS II will lose their function because Chlorophyll A is the major pigment that absorbs light energy in both photosystems.

In case 2, if PS I is inhibited and PS II is unaffected, a PROTON GRADIENT WILL STILL BE PRODUCED because the splitting of water into protons (H+) and electrons (e-) occurs in PSII. Hence, H+ ions can still be pumped into the inner membrane of the thylakoid in order to build a proton gradient even without the occurrence of PS I.

Which gaseous giants did Renaissance scientists such as Galileo know about?
Anna007 [38]

The correct answer is:

a. Jupiter

Explanation:

In 1610, Galileo Galilei turned his rudimentary telescope on Jupiter and understood that it had 4 large moons orbiting it: Io, Europa, Ganymede, and Callisto. This was an amazing discovery because it explained that Earth was not the center of the Universe as champions of the geocentric view assumed.

What is the argument against taking persistent vegetative state patients off of life support?
Leviafan [203]

Answer:

An argument could be that there have been many instances where people on life support or in a vegatative state have 'woken' up and gotten better after many years. So, taking someone off life saving machines could be taking away their chance of getting better and their chance of surviving. Since the person is not dead, some may even see it as murder.
