ALL BUT one product of the light dependent reaction of photosynthesis is utilized in the light independent reaction. That is
Lesechka [4]

Answer: Oxygen

Explanation: Photosynthesis is a process by which plants use carbon dioxide, water and sunlight to produce glucose and oxygen.

Photosynthetic reactions are divided into two phases: 1). light dependent reactions and 2). light independent reactions.

1) In light dependent reactions, chlorophyll and other light absorbing pigments absorb light energy and conserve it as ATP and NADPH with the simultaneous liberation of oxygen. This reaction occurs only when plants are illuminated. In light reactions, light energy is used to split water molecules into hydrogen ions and oxygen, the hydrogen ions produced are transferred to NADP+ to form NADPH, ATP is also produced in light dependent reactions.

2) In light independent reactions, ATP and NADPH produced in the light dependent reactions are used to drive the light independent reactions in which ATP and NADPH are used to reduce CO2 to form trioses, starch, sucrose and other products derived from them.

H2b = 3.3 x 10^6 molecules

H3 = 3.3 x 10^6 molecules

H4 = 3.3 x 10^6 molecules

Explanation:

It was mentioned in the book Principles of Genetics  By D. Peter Snustad, Michael J. Simmons that in the nucleus of <em>D. melanogaster </em>there will be 1.65 x 10^6 nucleosomes and 3.3 x 10^6 molecules of every type of histone i.e. H2a, H2b, H3, and H4 present in it.
