The energy from photons hitting photosystem iiis used to produce what?

ATP is produced when The energy from photons hitting photo system.

The correct answer is oxygen gas and hydrogen ion to power up the ATP synthesis.

Explanation:

Photosystem II is the very initial link in the chain of process of photosynthesis. It traps photons and utilizes the energy to excite and release the electrons from water. These excited electrons are used when the electrons are released the water molecule is converted into oxygen gas, which bubble up to environment and hydrogen ions used to power up ATP synthesis.

Thus, the correct answer is oxygen gas and hydrogen ion to power up the ATP synthesis.

kelp are large brown algae that live in cool, relatively shallow waters close to the shore. they grow in dense groupings much like a forest on land. these underwater towers of kelp provide food and shelter for thousands of fish, invertebrates, and marine mammal species.
