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