Next lesson. Photosynthesis, the process by which green plants and certain other organisms transform light energy into chemical energy. Photosynthesis takes place through several steps which occur during two stages: the light phase and the dark phase. The relative rate of photosynthesis is greatest under which conditions of light intensity and temperature? Our mission is to provide … The Calvin cycle. Up Next. Conceptual overview of light dependent reactions. 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. Both step 1 and step 2. Photosynthesis is a multi-step process that requires sunlight, carbon dioxide (which is low in energy), and water as substrates (Figure 3). Neither step 1 and step 2. Practice: Photosynthesis. Photosynthesis is a complex series of reactions carried out by algae, phytoplankton, and the leaves in plants, which utilize the energy from the sun. SURVEY . This is the currently selected item. 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. Photosynthesis evolution. Carbon fixation occurs during the light independent reaction of photosynthesis and is the first step in the C3 or Calvin Cycle. Photosynthesis occurs in two steps: Light reaction and Dark Reaction. During the steps in the light reaction stage, energy from the sun converts into chemical energy, while the Calvin cycle brings carbon dioxide fixation. 45 seconds . Breaking down photosynthesis stages. Photosynthesis is the process by which autotrophic plants make their own food. Photosynthesis. Which statement correctly describes the diagram? A) Respiration is the reversal of the biochemical pathways of photosynthesis. B) Photosynthesis stores energy in complex organic molecules, while respiration releases it. In a situation in which the respiration rate is greater than the photosynthesis rate, glucose consumption is higher than glucose production. Biology is brought to you with support from the Amgen Foundation. D) The exchange of oxygen and carbon dioxide occurs only in photosynthesis. Describe the main structures involved in photosynthesis All living organisms on earth consist of one or more cells. The light-dependent reactions. Sort by: Top Voted. Tags: Question 15 . The light-dependent reactions. Which statement best describes an aerobic heterotroph? 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. 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. B) The products of respiration can be used by plants for photosynthesis. Photosynthesis: Overview of the light-dependent reactions. The light-dependent reactions. A) The products of photosynthesis cannot be used by other organisms. Biology is brought to you with support from the. Which of the following statements best describes the relationship between photosynthesis and respiration? C) The exchange of oxygen and carbon dioxide occurs only in respiration. Co2, water, chlorophyll, and sunlight are four important requirements for this process. Photosynthesis review. Cellular respiration.
