Plants make their own food thru the process of photosynthesis

Plants vary greatly in size, shape, and the type of environment in which they live.

Types of Photosynthesis: C3, C4 and CAM

In the ~2.5 billion years since photosynthetic organisms have appeared daily in this performance, enough oxygen has accumulated to account for 21% of the atmosphere...

ATP is involved in other chemical reactions, such as respiration, which will be covered in a later program.

Photosynthesis converts moving radiant energy into stored chemical bond energy.

The action spectrum of photosynthesis is a graph showing the rate of photosynthesis for each wavelength of light. The rate of photosynthesis will not be the same for every wavelength of light. The rate of photosynthesis is the least with green-yellow light (525 nm-625 nm). Red-orange light (625nm-700nm) shows a good rate of photosynthesis however the best rate of photosynthesis is seen with violet-blue light (400nm-525nm).

Immediatelyafter exposure to 14CO2, the plant's photosynthetic tissue iskilled by immersing it in boiling alcohol, and all of the biochemical reactions cease.

Glycerate 3-phosphate is reduced during the reduction reactions to a three-carbon sugar called triose phosphate. Energy and hydrogen is needed for the reduction and these are supplied by ATP and NADPH + H+ (both produced during light-dependent reactions) respectively. Two triose phosphate molecules can then react together to form glucose phosphate. The condensation of many molecules of glucose phosphate forms starch which is the form of carbohydrate stored in plants. However, out of six triose phosphates produced during the reduction reactions, only one will be used to synthesise glucose phosphate. The five remaining triose phosphates will be used to regenerate RuBP.

Both the LHC and the reaction centers are membrane bound structures but there are no chloroplasts in the purple photosynthetic bacteria. The electron transfer processes occur within the cell membrane and the overall process is a cyclic one (i.e., there is no net oxidation-reduction). Protons are transferred across the membrane, from the cytoplasmic side to the outside, establishing a proton gradient whose dissipation drives ATP synthesis. A similar situation holds for the cyanobacteria and plants, but in these organisms, the process occurs in chloroplasts and the overall reaction is not a cyclic one.

In photosynthesis, how do 12 oxygen atoms come from 6 water molecules

Are you jealous of your green friends? It must be nice to sunbathe all day long. Before you become plant-green with envy (sorry…), remember that plants do not have the ability to eat milkshakes or French fries, and they can't ride a bike along the beach. Does that give you some satisfaction? Good.

By 1796, after further research, Ingenhousz was able to write the first equation for photosynthesis, which was:

Light is not directly usable in photosynthesis.
