which of the following molecules are products of photosynthesis?

Learn vocabulary, terms, and more with flashcards, games, and other study tools. The following points highlight the four main raw materials used in photosynthesis. Chlorophyll is a complex molecule. Water is released during photosynthesis and consumed during cellular respiration Photosynthesis occurs during the day, and cellular respiration occurs at night. The only function of chlorophyll is to trap the sunlight energy; chlorophyll is not produced or used up during photosynthesis. The main product of photosynthesis is glucose, which is the molecule that produces energy to run the processes of the cell. Six molecules of carbon dioxide and six molecules of water are needed to produce one molecule of glucose. Products of Photosynthesis The direct products of the light reactions and the Calvin cycle are 3-phosphoglycerate and G3P, two different forms of a 3-carbon sugar molecule. Two of these molecules combined equals one glucose molecule, the product seen in the photosynthesis equation. d. P700 absorbs light with a wavelength of 700 nm. If photosynthesizing green algae are provided with CO₂ synthesized with heavy oxygen (¹⁸O), later analysis will show that all but one of the following compounds produced by the algae contain the ¹⁸O label. Carbon Dioxide 2. Little free glucose is produced in plants; instead, glucose units are linked to form starch or are joined with fructose, another sugar, to form sucrose (see carbohydrate). glucose and O2. In addition to the absence of oxygen production, nonoxygenic photosynthesis differs from oxygenic photosynthesis in two other ways: light of longer wavelengths is absorbed and used by pigments called bacteriochlorophylls, and reduced compounds other than water (such as hydrogen sulfide or organic molecules) provide the electrons needed for the reduction of carbon dioxide. What are the parts of the ATP molecule? The basic function of the light reactions of photosynthesis is the conversion of … B) splitting water molecules. These sugar molecules contain energy and the energized carbon that all living things need to survive. d. P700 absorbs light with a wavelength of 700 nm. 1, 2, 3 and 4. 8.3: Using Light Energy to Make Organic Molecules. Oxygen is mainly a byproduct of the process of photosynthesis. ATP and carbon dioxide are used to make ADP and water. At first, the energy may have been used immediately to initiate reactions useful to the cell. Which of the following molecules are products of photosynthesis? As the light intensity increases to higher levels, however, the rate becomes saturated; light “saturation” is achieved at a specific light intensity, dependent on species and growing conditions. Oxygen is generated as a waste product of photosynthesis. Photosynthesis is the process in which chlorophyll molecules absorb the radiant energy from the sun and transfers it into chemical potential energy. For example, the accidental joining (condensation) of the amino acid glycine and the fatty acid acetate may have formed complex organic molecules known as porphyrins. the inability of water to donate its electrons to photosystem II. This oxygen is released into the atmosphere through the plant’s leaves. As the process for utilization of light energy continued to evolve, however, a larger part of the absorbed light energy probably was stored as chemical energy, to be used to maintain life. Explanation. Carbon Dioxide: In land plants, carbon dioxide is obtained from the atmosphere through the stomata. Describe the Calvin-Benson cycle in terms of its reactants and products. C) Photosynthesis occurs only in plants and respiration occurs only in animals. Of the following products, which is produced by both c. P680 is found in algae while P700 is found in land plants. Plants use photosynthesis to take in sunlight, water, and carbon dioxide as reactants and produce glucose for energy and oxygen. Compare the plant production of glucose and oxygen with the animal production of glucose and carbon dioxide. Carbon-based molecules from food and oxygen are used to make ATP. This means that the reactants, six carbon dioxide molecules and six water molecules, are converted by light energy captured by chlorophyll (implied by the arrow) into a sugar molecule and six oxygen molecules, the products. Although life and the quality of the atmosphere today depend on photosynthesis, it is likely that green plants evolved long after the first living cells. A)CO 2 and glucose B)H 2 O and O 2 C)ADP,℗ i,and … 20) Which of the following statements regarding photosynthesis is false? On a global scale, which one(s) of the following are products of photosynthesis and required for the lives of all aerobically respiring organisms? Photosynthesis occurs in membrane-bound structures called the chloroplasts. CO2. The products of the light-dependent reactions of photosynthesis are. The products of photosynthesis are. Name: _ Date: _ Photosynthesis and respiration worksheet – Gr 11 IB Bio SL 1. molecules – carbon dioxide. The plant having high concentration of chlorophyll-b but lacking chlorophyll-a will not carry out photosynthesis. The reactants in photosynthesis are Water and carbon dioxide Which of the following is not an expected outcome of global climate change? Both photosynthesis and cellular respiration occur in the chloroplasts of a cell. The products of photosynthesis are glucose and oxygen. When Earth was young, electrical storms and solar radiation probably provided the energy for the synthesis of complex molecules from abundant simpler ones, such as water, ammonia, and methane. Of the following, which two represent the primary functions of photosynthesis? a. Respiration is the reversal of the biochemical pathways of photosynthesis. Water is also a product of photosynthesis. This water is produced from the oxygen atoms in the carbon dioxide molecules. Oxygen is also a product of photosynthesis. the reactants of cellular respiration. These stages can be distinguished by studying the rates of photosynthesis at various degrees of light saturation (i.e., intensity) and at different temperatures. Start studying Photosynthesis. Photosynthesis Reactants The photosynthetic process requires several simple reactants. Which of the following is a product of photosynthesis? Solution for The products of photosynthesis are carbohydrate molecules and O2. Oxygen is produced during photosynthesis and used during cellular respiration. Photosynthesis consists of two stages, the light reactions, and the dark reactions. Molecules of chlorophyll, the key photosynthetic pigment in green plants, are arranged within a leaf such that they minimize the plant's need to transport incoming solar radiation while also increasing a leaf's photosynthetic output.
