Lab - Hill's reaction

Excerpt from the official document:
Senior Year – Specialty: Energy and Living Cell

Scientific Issue:
Light enables the production of organic matter (glucose) and oxygen within chloroplasts from mineral molecules (carbon dioxide, water):
Towards the end of the 1930s, Robert HILL (1899 – 1991), an English biochemist, hypothesized that the production of oxygen by chloroplasts requires the presence of an electron acceptor (an oxidant) in addition to light.

Procedure:
The objective is to measure the evolution of oxygen concentration in a suspension of damaged chloroplasts placed under different experimental conditions to test Robert HILL's hypothesis:
The production of oxygen by a suspension of chloroplasts occurs in light in the presence of an electron acceptor (oxidant).
