Exam 19: The Light Reactions of Photosynthesis

In green plant photosynthesis, how many protons are transferred into the thylakoid lumen after absorption of four photons to PSII and four photons to PSI?

Humans do not produce energy by photosynthesis. Why, then, is this process critical to our survival?

Electrons flow from photosystem II to photosystem I through the ________________ complex.

What organelle is the site of photosynthesis?

The transfer of excitation energy from one molecule to one nearby through electromagnetic interactions is called ________________________________.

Which of the following is/are light harvesting molecules?

______________________ is the term for a bacteriochlorophyll that has two protons instead of a magnesium ion at its center.

What is the immediate source of the electron regained by the oxidized P960 in bacterial photosynthesis?

Chloroplasts are similar to mitochondria in that they

The pathway of electron flow from H₂O to NADP⁺ in photosynthesis is referred to as

After P960 absorbs light, what are the next few steps in bacterial photosynthesis?

In bacterial photosynthesis, how would the light energy be used if the reduced bacteriopheophytin (BPh ^- )returned the electron to the P960⁺ cytochrome?
