Homework Answers
a) Oxidation
Explanation: During photosynthesis, the transfer of electrons from water take place via some electron carrier and yields oxygen. In this electron electron are released from water. So, it is called oxidation reaction. Reduction reaction of photosynthesis occurs when carbon-di-oxide (CO2) is converted to sugar. Hydrolysis and condensation reaction does not involved in light reaction of photosynthesis.

What happens along an electron transport chain?
What happens along an electron transport chain? Electrons are passed from a reducing agent to an oxidizing agent, releasing free energy at each step. Electrons are passed from molecule to molecule, gaining potential energy at each step. O Electrons store energy that can be used to break down sugar molecules. O Protons are pumped through ATP synthase, making ATP.
