Summary Introduction

Introduction:

The light-dependent reaction of photosynthesis contains two pigments. The photosystem I and photosystem II that absorb the light at a wavelength of 700 nanometers and 680 nanometers. The electron moves from photosystem II to I in a zigzag motion to finally produce ATP and NADPH.

The main purpose of the light reactions in photosynthesis is Group of answer choices to take the high energy electrons out of glucose. to generate ATP and NADPH to send to the Calvin Cycle. to produce all the ATP the plant cell needs for its cellular work. to produce enough oxygen gas for humans to survive.
Which of the following occurs during the carbon-fixation reactions of photosynthesis? A. Water is converted into hydrogen and water. B. CO2 is converted into sugars. C. Chlorophyll acts as an enzyme. D. Nothing occurs; the plant rests in the dark. E. Glucose and oxygen are reduced to CO2 and water.
