Photosynthesis: Overview of the light-dependent reactions. During photosynthesis in green plants, light energy is captured and used to convert water, carbon dioxide, and minerals into oxygen and energy-rich organic compounds. Photosynthesis is a complex series of reactions carried out by algae, phytoplankton, and the leaves in plants, which utilize the energy from the sun. C) The exchange of oxygen and carbon dioxide occurs only in respiration. Our mission is to provide … Co2, water, chlorophyll, and sunlight are four important requirements for this process. Photosynthesis is the process by which autotrophic plants make their own food. Up Next. The rate of respiration depends on the energy needs of the plant while the rate of photosynthesis varies depending on the availability of light energy, if all other conditions are maintained the same. Which statement correctly describes the diagram? Neither step 1 and step 2. Breaking down photosynthesis stages. Biology is brought to you with support from the. Photosynthesis evolution. SURVEY . Photosynthesis is a multi-step process that requires sunlight, carbon dioxide (which is low in energy), and water as substrates (Figure 3). In a situation in which the respiration rate is greater than the photosynthesis rate, glucose consumption is higher than glucose production. After the process is complete, it releases oxygen and produces glyceraldehyde-3-phosphate (GA3P), simple carbohydrate molecules (which are high in energy) that can subsequently be converted into glucose, sucrose, or any of dozens of other sugar molecules. Conceptual overview of light dependent reactions. B) Photosynthesis stores energy in complex organic molecules, while respiration releases it. The light-dependent reactions. Photosynthesis review. Cellular respiration. 45 seconds . The light-dependent reactions. A) The products of photosynthesis cannot be used by other organisms. Biology is brought to you with support from the Amgen Foundation. Photosynthesis takes place through several steps which occur during two stages: the light phase and the dark phase. The Calvin cycle. Photosynthesis occurs in two steps: Light reaction and Dark Reaction. Both step 1 and step 2. Photosynthesis. Sort by: Top Voted. Which statement best describes an aerobic heterotroph? During the steps in the light reaction stage, energy from the sun converts into chemical energy, while the Calvin cycle brings carbon dioxide fixation. Photosynthesis is defined as one process, but contains two distinct stages, which in turn break down into a series of steps. Practice: Photosynthesis. Describe the main structures involved in photosynthesis All living organisms on earth consist of one or more cells. D) The exchange of oxygen and carbon dioxide occurs only in photosynthesis. Tags: Question 15 . Each cell runs on the chemical energy found mainly in carbohydrate molecules (food), and the majority of these molecules are produced by one process: photosynthesis. Next lesson. Photosynthesis, the process by which green plants and certain other organisms transform light energy into chemical energy. The light-dependent reactions. A) Respiration is the reversal of the biochemical pathways of photosynthesis. This is the currently selected item. The relative rate of photosynthesis is greatest under which conditions of light intensity and temperature? Which of the following statements best describes the relationship between photosynthesis and respiration? B) The products of respiration can be used by plants for photosynthesis.
