In the first step, energy from light is stored in the bonds of adenosine triphosphate (ATP), and nicotinamide adenine dinucleotide phosphate . This happens when the C4 acid from the mesophyll is broken down in the bundle sheath cells to release Carbon dioxide which further results in the increasing the intracellular of carbon dioxide. Photosynthesis is the process by which plants and some microorganisms make substances like carbohydrates. 4.Formation of molecular oxygen- Hydroxide ion is oxidised to hydrogen peroxide which decomposes to form molecular oxygen (O2).

Long Answer Questions (5 marks each) 21. There are several ways of measuring the rate of photosynthesis in the lab. The chlorophyll in these living organisms, which also contributes to their green hues, absorbs the sunlight and combines it with carbon dioxide to convert these compounds into an organic chemical called adenosine … 3.Production of reducing agent- NADP (nicotinamide dinucleotide phosphate) picks up the hydrogen ion and is reduced to NADPH. Afraid of a subject or a topic? Molecular oxygen is released during photosynthesis. While a 3-carbon molecule is the direct result of photosynthesis, glucose is simply two of these molecules combined and is often represented as the direct result of photosynthesis due … Time between peak 14C at tp of trunk and bottom. Class-10 » Science. *Response times vary by subject and question complexity. This video explains the factors affecting the rate of photosynthesis. The rapidity of its emergence suggests it was no fluke and could arise on other worlds, too. Explain briefly, micturition and disorders of the excretory system. Photosynthesis is a process used by plants and other organisms to convert light energy into chemical energy that can later be released to fuel the organisms' activities. In photosynthesis, the inorganic compounds of carbon dioxide, water, and sunlight are used by photoautotrophs to produce glucose, oxygen, and water. This phase occurs in the thylakoids of the chloroplast. Long Answer Type Questions.

This phase occurs simultaneously with the light-dependent reaction. Explain how the transport of sodium ions is involved in the absorption of glucose by epithelial cells. 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. It begins when rubisco acts on oxygen instead of carbon dioxide. cycle of chemical reactions performed by plants to “fix” carbon from CO2 into three-carbon sugars Explain how the products of photosynthesis are both loaded into and unloaded out of vascular tissue. Two main phases are involved in the mechanism of photosynthesis:light dependent phase and light independent phase. Photosynthesis - Photosynthesis - Carbon fixation in C4 plants: Certain plants—including the important crops sugarcane and corn (maize), as well as other diverse species that are thought to have expanded their geographic ranges into tropical areas—have developed a special mechanism of carbon fixation that largely prevents photorespiration.

What other information is required in order to calculate the mean rate of movement of the 14C down the trunk? Spell. The chloroplasts of plants use a process called photosynthesis to capture light energy from the sun and convert it to chemical energy stored in sugars and other organic molecules. It evolved as an adaptation to high light intensities, high temperatures, and dryness. The most common and abundant pigment is chlorophyll a. It occurs in the stroma of the chloroplast. Therefore, C 4 plants dominate grassland floras and biomass production in the warmer climates of the tropical and subtropical regions (Edwards et al., 2010). - edu-answer.com Photosynthesis is very important for life on Earth.

Long answer type questions . in deail. Long answer type questions . It is easy to think of light as something that exists and allows living organisms, such as humans, to see, but light is a form of energy. 5.Photophosphorylation- Electrons are used in converting ADP (adenosine diphosphate) into energy-rich compound ATP (adenosine triphosphate) by adding one phosphate group.The process of addition of phosphate is called phosphorylation. HARD. long answer please. In this way, they coordinate with each other and photosynthesis occur. 2.Photolysis of water- Energy absorbed is used in the splitting of water molecules into hydrogen ion (H+) and hydroxide ion (OH−). The sugars are used by the cell as energy, and to build other kinds of molecules. In the first part of photosynthesis, the light-dependent reaction, pigment molecules absorb energy from sunlight. A further mechanism of regulation for photosynthesis that prevents overreduction of the PSI acceptor side and the chloroplast stroma is the “malate valve” system, which transfers reducing equivalents to the cytosol (Scheibe et al., 2005). If you can remember the chemical formula for both photosynthesis and cellular respiration, if you can explain how the two processes complement one another, and if you can explain what happens when there is not enough oxygen for cellular respiration, then you've learned what you need to have learned.
