What does water do in green plant photosynthesis?
Q. I cannot find the answer to this anywhere. The way the question is worded, it is In green plant photosynthesis, water is ___? It's a multiple choice question. The possible answers are: an electron acceptor used to have Ru BP reduced to hydrogen gas oxidized to O2 in the dark oxidized to molecular oxygen (O2) in the light Any help on this would be greatly appreciated! Thanks!

A. H2O donates an electron, so one isn't right Ru BP relates to CO2...so I don't think so It is reduced to a hydrogen ion that binds with NADP+...so I don't think so... It occurs during the light reaction so the oxidation in the dark...no YES! It is converted to O2 during the light reaction...Last answer is correct...That's why plants "breathe" out O2.

Do photosynthesis and respiration occur at the same time in a plant?
Q. Do photosynthesis and respiration occur at the same or different times? Where does respiration take place in a cell?
Asked by Cho - Sun Jun 14 14:18:13 2009 - Botany - 2 Answers - Comments
A. photosynthesis occurs during the daytime, it's when light energy is converted into chemical energy (ATP) to be used to split water molecules to get hydrogen, the oxygen is released through the stomata, ATP is made in the grana. The remaining energy and hydrogen are passed in to the stroma, the thick liquid between grana. Carbon dioxide by now has been let into the leaf through the stomata and the energy is used to convert hydrogen and carbon dioxide into simple carbohydrates. This is respiration and occurs when there is no light ( light-independent reaction) Photosynthesis occurs in the grana. Respiration occurs in the stroma. Stroma and grana are both contained within a chloroplast.

How does air pollution affect photosynthesis?
Q. I need this as quick as possible... Can any one tell me a detailed but not textbook-ed situation or example of how air pollution affects photosynthesis and how it affects photosynthesis in plants?
Asked by davidplastique - Mon Sep 24 00:25:04 2007 - Botany - 2 Answers - Comments
A. Well, smog can block out light that is needed for photosynthesis. I bet it also messes with the chemical reaction the plant goes through converting CO2 to sugars and oxygen. Air pollution sometimes comes out of the sky with the rain as "acid rain." This harms the leaves of a plant, which reduces how well it can conduct photosynthesis.

How can you tell the products of photosynthesis exist?
Q. For example, in a lab experiment, how would I determine the products of photosynthesis are glucose and oxygen. Is there anyway that i can collect the products to prove they exist?
Asked by HappyKnife - Sun Jan 16 17:09:19 2011 - Botany - 1 Answers - Comments
A. Oxygen is easy - especially if you use a pond plant. The oxygen gas bubbles out and you can collect it, and test it with a glowing splint. It is possible also to test leaves for glucose (or you could measure the mass of organic matter before/after a period of photosynthesis), but easier is to test a leaf for starch, using iodine solution.

How do photosynthesis and respiration relate to the Greenhouse Effect?
Q. There is current controversy as to whether the atmosphere is warming due to the burning of fossil fuels and the destruction of the rainforests (i.e., the Greenhouse Effect). How does photosynthesis and respiration relate to this controversy?
Asked by - Sun Apr 3 20:29:49 2011 - Biology - 1 Answers - Comments
A. Aerobic cellular respiration produces carbon dioxide, which is a greenhouse gas, and thus would contribute to the Greenhouse Effect. Photosynthesis removes carbon dioxide from the atmosphere (to make glucose and then cellulose among other things), and thus photosynthesis would reduce the Greenhouse Effect. Removal of rainforest would tip the dynamic balance, putting more carbon dioxide into the atmosphere and reducing photosynthesis. *shrug*

A. Photosynthesis is an anabolic pathway where smaller molecules are used to build larger ones such as glucose. Photons of light hit the plastids of photosystem II which causes a transfer of excited electrons to the reaction center of PS II. A water molecule splits in PSII to replace the electrons of the special chlorophyl that passed its electrons tot he primary electron center. That electron is then passed to an electron transport chain that pumps hydrogen atoms across the membrane which forms a concentration gradient.

Asked by Mandyluvs Nicklikewhoa - Wed Apr 14 23:36:04 2010 - Biology - 2 Answers - Comments
A. In the short version, water gets used up during photosynthesis. Water gets pulled up from the ground, into the roots and up to the leaves. The leaves then release Oxygen and water vapor and what not. The two biggest contributing factors to the water cycle are transpiration and evaporation. Water evaporates from the leaves and also is released. And if you make the right connections, you'll see how this relates to the water cycle.

Photosynthesis is a process by which plants and other organisms convert light energy into chemical potential energy that organisms can use for cellular processes. As we usually think about it, photosynthesis allows plants to "fix" the carbons from carbon dioxide into sugars. Fortunately for us, we have a way to break down the sugars in starch, and convert that chemical potential energy back into something we can use directly for stuff we want to do (e.g. ATP to allow you to move, think, build stuff, and reproduce).

Can green plants do photosynthesis with only green light?
Q. Green plants are green because they reflect green light. So when put under green light they shouldn't be able to undergo photosynthesis. However, assuming that there are carotenoids in the leaf, would it be able to go undergo photosynthesis and survive? Or would stored energy be used for photosynthesis?

Have a squizz at this graph As to whether a plant would be able to survive under green light alone, I'm not entirely sure. It would be able to undergo photosynthesis, but at a very slow rate. Whether this rate is high enough to sustain the plant would probably depend on the plant itself, and its relative concentrations of the different photosynthetic pigments.

A. Wavelength determines energy level. The larger the wavelength, the lower the energy. In visible light, red has the largest wavelength/lowest energy and violet has the smallest wavelength/highest energy. Pigment molecules in photosynthesis are adapted to capturing particular wavelengths, or colors, of light.

What if being in the dark or light affected not only the rate of photosynthesis, but increased or decreased metabolic demands on the cell, changing the rate of respiration also?

A. That's a really big question! Photosynthesis is basically a route by which light energy is converted to chemical energy. It's 'role' is to produce energy (in the form of carbohydrates - fructose/sucrose etc.) for photosynthesizing organisms, namely plants, algae and some microorganisms including some bacteria. It is 'involved' in the Calvin cycle, (which is a light-independent cycle, using energy stored in electrons in the stroma of chloroplasts to convert water and Carbon Dioxide in to different organic compounds which can be used for energy). The chemical equation is: 6 CO2 + 12 H2O C6H12O6 + 6 O2 + 6 H2O Carbon dioxide + water Carbohydrate + Oxygen + water Most plants are able to produce energy from chemical compounds, using energy they… [cont.]
