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