question 4 (1 point)
in photosynthesis, oxygen is produced during:
a) the light independant reaction
b) non - cyclic photophosphorylation
c) cyclic photophosphorylation
d) the calvin cycle

Explanation:

In photosynthesis, oxygen is produced during non - cyclic photophosphorylation. Water is split (photolysis) in this process, releasing oxygen as a by - product. The light independent reactions (Calvin Cycle) use the products of the light reactions but do not produce oxygen. Cyclic photophosphorylation does not involve the splitting of water and thus does not produce oxygen.

Answer:

B. non - cyclic photophosphorylation
