Photosynthesis light dependent reaction ppt

Photosynthesis occurs in two sets of reactions that are linked by electron carrier molecules (NADP + /NADPH) and ADP/ATP. The two reactions go by several names. I'll be sticking to light reactions and Calvin cycle. (Alternate names you might have heard for the light reactions: photochemical reactions, light-dependent reactions. The light dependent reactions takes place in the membrane of the chloroplast (thylakoids), as this location offers a large surface area to absorb light energy. The light independent reactions take place in the stroma of the chloroplast. Setting. The structure of a plant is conducive to photosynthesis. The main photosynthetic part is the leaf.

light. Is photosynthesis an ENDERGONIC or EXERGONIC reaction? Photosynthesis is an endergonic reaction. because it requires an input of energy to occur; that energy comes in the form of light. This is a review from the previous PowerPoint, to activate students' prior knowledge.Aug 16, 2010 · Photosynthesis consists of two parts: 1. Light reaction. 2. Dark reaction (calvin-benson cycle) The whole idea of photosynthesis is to take inorganic carbon dioxide and reduce it to organic sugars. During the light reaction, light energy (termed photons) is captured by pigment molecules in the chloroplast.

Part IV: Light and Dark Reactions The whole process doesn't happen all at one time. The process of photosynthesis is divided into two main parts. The first part is called the light dependent reaction. This reaction happens when the light energy is captured and pushed into a chemical called ATP. Light independent reactions depend on light dependent reaction for supply of APT, NADPH. Explanation: Whole processes of photosynthesis have been broadly divided into light reaction and dark reaction. The light reaction is completed in the grana of chloroplast in presence light, while the dark reaction is completed in stroma in light and dark both.
