Describe and Draw the path of electron through the light reactions. Indicate where (1) ATP, (2) NADPH and (3) oxygen are produced.
Homework Answers
Answer: In photosynthesis the green plant trap the light energy from sun and fixed into chemical energy in association with environmental carbon dioxide (CO2) and water. The fixed energy is essential for sustaining of life on earth.
6CO2 + 6H2O + sunlight---------------à C6H12O6 + 6O2
The complete photosynthesis takes place in sets of reactions
Light dependent reaction and light independent reactions (Dark reaction/Calvin cycle). In light dependent reaction takes place in thylakoids membrane of chloroplast and photosynthesis energy (ATP) and reducing equivalents (NADPH) are produced that help in dark reaction to produce glucose (C6H12O6)
Light reaction:
H2O + Sunlight+ Chloroplast (thylakoid)--------------à O2 + ATP + NADPH

Lab 8 Spring 2020 The Light Reactions The light reactions begin with the photolysis of water. Photolysis refers to the process by which, in the Intact thylakoid membranes and light. water is split into oxygen protons and electrons. Therefore, was primary electron donor in photosynthesis. Conversion of water, a very stable molecule, to oxygen is er unfavorable and would not occur to any significant extent without input of light energy in photosystem e process by which,...

The path of an electron during the light reactions of photosynthesis it is best described this way: PS I → ETC I → PS II → ETC II → water → NADPH water → PSII → ETC II → PS I → ETC I → NADPH ETC I → PS I → NADPH → ETC II → PS I → water PS II → ETC II → PS I → ETC I → NADPH → water

Put the following steps of the light reactions in the correct order: Light excites an electron from photosystem I. Light excites an electron from photosystem II. Electrons reduce NADP+ to NADPH. Electrons pass through an electron transport chain, which generates a H+ gradient used to make ATP.
