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