Chapter 5, Problem 3MCQ
Summary Introduction
Introduction:
Photosynthesis is a process that takes place in green plants to construct complex organic compounds from water and carbon dioxide with the help of chlorophyll and sunlight. The whole process is completed in two steps; light reaction and dark reaction. ATP (adenosine triphosphate) production takes place in the light reaction of photosynthesis. This ATP is used to reduce

Students have asked these similar questions
Define the following terms: a. photosynthesis b. photosystem c. light harvesting antenna d. reaction center e. chlorophyll
Which of the following structures is not a component of a photosystem? a. ATP synthase b. antenna molecule c. reaction center d. primary electron acceptor
Students are preforming an experiment to study the role of light in photosynthesis. They place an Elodea plant into a large test tube with water and assemble a volumeter using a cork and calibrated glass tubing. Then, the apparatus is placed near a lamp. Soon after, the water level in the tubing begins to move upward. Why does the edge of the water move upward?
