Photosynthesis light dependent reactions 1. PhotosynthesisLight Dependent Reactions Dr. Mark A. McGinleyHonors College and Department of Biological Sciences Texas Tech University 2. Purpose of Photosynthesis• Photosynthesis converts electromagnetic energy in light to potential energy (sometimes called chemical energy) stored in chemical bonds of glucose — The potential …

Explain each limiting factor in terms of the light dependent and light independent reactions. Photosynthesis (Part 2) Light Independent stage Energy from ATP. hydrogens and electrons from reduced NADP are used to reduce carbon dioxide to produce carbohydrate. This happens in the stroma. Light independent stage What happens without light? Which stages can still continue when the light …

The light dependent reaction 1. The light dependent reaction Photosynthesis 2. One can think of the light dependent reactions as a way to increase the free energy of the system and the light independent reactions as a way to convert that new free energy into the bonds of glucose.

Photosynthesis is a process that converts energy from an “un-usable form” (light) into a “usable form” (organic compounds). and requires an intermediate step (ATP/NADPH). This is a review from the previous PowerPoint. to activate students’ prior knowledge. Phase 2: The Calvin Cycle

The Hill Reaction depends on electrons released during the light-dependent stage of photosynthesis being picked up by the. blue electron acceptor DCPIP. The reaction can only occur if the thylakoid membranes are . illuminated . as the light-dependent stage stops in the dark. DCPIP is . blue. when oxidised (at pH 7. 0) and colourless when reduced. so it is possible to monitor the . loss of blue . . .

Overview of Photosynthesis• Photosynthesis can be divided into 2 stages: — Light Reactions — Light energy is converted to chemical energy. which is temporarily stored in ATP and NADPH. — Calvin Cycle — Sugars are formed using CO2 and the chemical energy stored in ATP and NADPH. 7.

DEFINITION OF PHOTOSYNTHESIS • Is the process by which autotrophic organisms use light energy to make sugar and oxygen gas from carbon dioxide and water. • Occurs in plants. algae and some prokaryotes • Anabolic (small molecules combined) • Endergonic (stores energy) • Stored as carbohydrate in their bodies. 4.
