Feb 11, 2019 · The light-dependent reactions use light energy to make two molecules needed for the next stage of photosynthesis: the energy storage molecule ATP and the reduced electron carrier NADPH. Dark reactions make use of these organic energy molecules (ATP and NADPH). This response cycle is also called Calvin Benison Cycle, and it occurs in the stroma.
This is the rate of photosynthesis at that particular temperature. The gas should be checked to prove that it is indeed oxygen - relights a glowing splint. Repeat at different temperatures: 0°C - surround the beaker with an ice jacket; greater than room temperature (25°C, 30°C, 35°C, 40°C, 45°C, etc.,) by using a hot plate.
Photosynthesis: The Role of Light The heart of photosynthesis as it occurs in most autotrophs consists of two key processes: the removal of hydrogen (H) atoms from water molecules; the reduction of carbon dioxide (CO 2) by these hydrogen atoms to form organic molecules. The second process involves a cyclic series of reactions named (after its discoverer) the Calvin Cycle.
The Light Reaction (Hill Reaction). Photosystem II (PS II): The light-driven reaction of photosynthesis also called light reaction (Hill reaction), referred to as electron transport chain, were first propounded by Robert Hill in 1939. The electron transport chain of photosynthesis is initiated by absorption of light by photosystem II (P 68o).
Describe the role of chlorophylls and other pigments in photosynthesis. Summarize the main events of the light dependent reactions. Explain how ATP is made during the light reactions. Summarize the main events of the Calvin cycle. Describe what happens to the compounds that are made in the Calvin cycle.

Cellular Respiration and Photosynthesis co-exist as paired metabolic processes. Photosynthesis uses light energy to convert carbon dioxide into glucose, a simple sugar, in two steps, the light dependent and light independent reactions. Oxygen is produced . Science. Which statement is true about the products of cellular respiration?
What is the purpose of splitting water in PS2 of the light dependent reaction? ... Where do the light reactions happen? ... Photosynthesis - Light Reactions . 2.0k ...
since the 1800s: In the presence of light, the green parts of plants produce organic compounds and oxygen from carbon dioxide and water. Using molecular formulas, we can summarize the complex series of chemical reactions in photosynthesis with this chemical equation: 6 CO 2 + 12 H 2 O + Light energy → C 6 H 12 O 6 + 6 O 2 + 6 H 2 O We use glucose (C 6 H 12 O 6
