Membrane in a chloroplast where the light reactions of photosynthesis occur. Light reactions. Reactions of photosynthesis that use energy from light to produce ATP and NADPH. PS I. Oxidized by light and electrons used to reduce NADP+ to NADPH. PS II. Oxidized by light and electrons used to create a proton gradient for ATP synthesis.
Describe the overall process of photosynthesis, including the reactants and products. Photosynthesis uses the energy of sunlight to convert water and carbon dioxide (reactants) into high-energy sugars and oxygen (products). A plant's leaves are the primary site of photosynthesis. A plant's leaves would be expected to have a large amount of

additional ATP is created from glucose. excess NADPH is reused in the light reaction. Score =. Correct answers: Quiz over photosynthesis that focuses on how oxygen is split, providing and electron that eventually results in the formation of ATP. This is an advanced quiz intended for students in AP Biology.
pigment and sugars. proteins and water. 10. When electrons are passed through an electron transport chain, released energy. is lost as heat. splits water into hydrogen and oxygen. fuses carbon dioxide molecules into a sugar. is transformed into a hydrogen ion gradient to drive ATP synthesis. Score Quiz.
In the light-dependent reactions, energy absorbed by sunlight is stored by two types of energy-carrier molecules: ATP and NADPH. The energy that these molecules carry is stored in a bond that holds a single atom or group of atoms to the molecule. For ATP, it is a phosphate group, and for NADPH, it is a hydrogen atom.

The net-reaction of all light-dependent reactions in oxygenic photosynthesis is: 2H 2 O + 2NADP+ + 3ADP + 3Pi → O 2 + 2NADPH + 3ATP Key Points Light energy splits water and extracts electrons in photosystem II (PSII); then electrons are moved from PSII to cytochrome b6f to photosystem I (PSI) and reduce in energy.
