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