Robin Hill discovered that the isolated chloroplasts from plants can release oxygen when they are illuminated by sunlight in the presence of a suitable electron acceptor. This showed:
I. oxygen (${\mathrm{O}}_2$) is produced by a reaction that is separate from carbon dioxide (${\mathrm{CO}}_2$) fixation.
II. the reaction in which oxygen is released requires light.
III. the light dependent reaction of photosynthesis is a result of a series of redox reactions.
1. I and II only
2. I and III only
3. II and III only
4. I, II and III

The reactions of the Calvin cycle can take place as long as which of the following products of the light dependent reactions are available?

The factors that can be limiting for the light independent reactions of photosynthesis are:
1. ${\mathrm{CO}}_2$, temperature, and light
2. ${\mathrm{CO}}_2$, light, and water
3. water, temperature, and ${\mathrm{CO}}_2$
4. oxygen, water, and temperature

The absorption spectrum in the given diagram will be of:
  

The reactions of the Calvin Cycle occur in:

The wavelengths of light most useful in photosynthesis are:

The correct chronological sequence of protein complexes in the thylakoid membrane involved in light reactions is:

The enzymes for synthesis of organic molecules, in autotrophic bacteria, are located:
1. on chloroplast membranes
2. in the cytosol
3. in the nucleoid region
4. along the inner surface of the plasma membrane

Oxygen, during oxygenic photosynthesis, is produced during:
1. cyclic photophosphorylation
2. the light-dependent reactions involving photosystems I and II
3. Calvin cycle
4. the Krebs cycle

The ions comprising the Oxygen Evolving Complex associated with PS II are:
